[Robert Verish via Meteorite-list]

This might be old news to those of you on facebook, but for those of us who are 
not, 
here is some news out of the MetSoc Meeting: 

Gold hunters in southern Russia might have been disappointed to learn that 
the speckled, yellow rock they uncovered was not a sizeable pebble of valuable 
metal. 
Instead, it was a rare piece of space-borne rubble containing a new mineral 
that 
had never before been seen on Earth.

The mineral came from the Uakit meteorite, named for the Russian location
where it was found. Scientists recently presented their discovery of the
meteorite's new mineral, named uakitite, at the Annual Meeting of the
Meteoritical Society in Moscow:  

https://www.hou.usra.edu/meetings/metsoc2018/pdf/6252.pdf

[MexicoDoug via Meteorite-list]

Thanks Doug,
Got to really dig into this paper to make sense of the conclusion which is only 
speculative and needs 
to be further evaluated for positive confirmation bias and field and lab work 
around the world.  It was 
quite top heavy on analysis which appears well done!

The authors, or maybe it was the press, used the study's 270 kg dissolved 
sample of well-characterized 
"chronostratigraphic" sediments from a Russian deposit in the study which got 
approved for publication 
in the prestigious journal, "Nature", if I read it correctly.  

It would have been more rigorous for my taste if it had been reviewed by MAPS 
editors, or the like, where the focus
 would have been more on interpretation, than on methodology.  Just my opinion, 
as both are important.  
It is an interesting subject - do we call it paleo-meteoritics? Getting any 
paper into Nature deserves congrats
for sure but I expected to be more awed from their editorial staff choices.  
Luckily no one told that to the Alvarez'.

In the end the conclusion is that ordinary chondrites used to be a 
significantly lower proportion of finds, nearly a 
half billion years ago according to the results of their study.  Then 466 mya 
that all changed with the disruption
of an L parent body.  I didn't notice special mention of H- or L-chondrites, so 
the assumption IMO is that that another
event happened recently.  None of this seems remarkably insightful but perhaps 
the authors point of view is 
that here's a smattering of evidence that confirms the idea that the ratios of 
meteorite classes will vary throughout 
geological ages which is nice when things make sense and people begin to 
dimension it with the 'fossil' record.

Kindest wishes
Doug

Hi Doug,

Here is a link to the original paper:

http://www.nature.com/articles/s41550-016-0035

"Our data show that the meteorite flux has varied over geological time as 
asteroid disruptions create new fragment populations that then slowly fade away 
from collisional and dynamical evolution. The current flux favours disruption 
events that are larger, younger and/or highly efficient at delivering material 
to Earth."

[MEM via Meteorite-list]

AS I understod it, Doug they did an isotope /element count(?) of a breccia 
known as the Buttermere Formation believing it to be composed of bombarded 
Earth Rock. I didn't catch that the age was Ordovician but I might have missed 
that. I do not know the time span nor if their are any other contemporaneous 
exposures that show a similar collection of apparently extraterrestrial 
material.  I only scanned the article quickly but did look up the formation--it 
is near the Wales England border.  Be it remembered that all of the UK isles 
are a hodgepodge of sutured pieces of rocks terranes covering recent to very 
ancient.  Buttermere's original plate is long gone.

I've done a lot of work in Ordovician rocks and haven't seen any sign.  I have 
run into 4 sites in  Carboniferous material that I am fairly sure were fossil 
meteorites.  Once, I found a series of nodule cavities on a ripple marked 
sandstone boulder which I took photos of but, when I returned with a diamond 
saw to retrieve them the boulder had been moved to the crusher.

Elton

"Rare meteorites common in the Ordovician period"

Ordovician meteorite hunters must have been brachiopods (Team Brachinite).  

Do the authors understand or speculate how different the absolute "flux" was 
for achondrites, for anyone reading this?

In other words, are the ordinary chondrites just less common 467 mya making 
this a better title:

"Common meteorites rare in the Ordovician period"

Big difference ... Otherwise the hypothesis is sensible ... that through the 
ages the relative frequency of meteorite types goes up and down depending on 
the latest collisions and shipping lanes ...

Ensisheim meteorite fall of 1492. The second a very belated write up
of a BIMS visit to Appley Bridge back in 2012.

You can see both here:

   I save all of the Meteorite Photos of the Day posts from the Met List.  
Something weird and distressing has happened.  It appears that all of the 
photos sent to me over the years have been magically turned into the photo of 
the thin slice of Zagami submitted by Peter Marmot.  So now I have hundreds of 
photos of the Zagami slice.  Mercy!


  Has this happened to anyone else?

[meteorite-list] Off subject--Halloween Special

[Don Merchant via Meteorite-list]

Hi List. Sorry if this is off Subject...As many as you may know or not, one 
of my hobbies is the study of the haunted paranormal. I had the fortunate 
opportunity to study for about 5 years one of the most haunted places in the 
United States called Rolling Hills...a former insane asylum! During this 
time I created a CD on the history and findings of Rolling Hills, much like 
a virtual tour. Below is the Link to my Website

*
Anyways...since today is Halloween, and Happy Halloween by the way, I 
thought I would send out a Halloween Treat to the List for those who can 
find some time today/tonight to check out the Video and listen to the CD 
virtual tour. Best to listen to the CD with headphones to get the best 
affects but not necessary. Your welcome to share it with family and friends 
to give a scare!

Hello list, 
The first thing I tried to do when I started my box company 10 years ago was to 
try to find someone to make a high quality riker display box at a reasonable 
price. I was unable to do so until late last year. I have two sizes now and am 
adding a larger 7.5 X 10.75 inch size next month. I will also have a nice foam 
insert with black on one side and white on other for about for smaller boxes 
and  for foam for larger box. You can look at rikers at 
http://www.rockboxes.com/ and I will list some on ebay as soon as I am able. I 
am getting a new knee tomorrow so will be out for a couple of weeks.
Thanks, Fred Olsen, Denver

 Welcome to the game, Doug.

Don't confuse tektites with meteorites, because they are quite
distinct species.  But they seem to have an inter-related history that
ends up putting them in many of the same collections.

And you live quite close to a hot-bed of discovery and debate about
tektites.   Check out the info on the Healdsburg variety.

I've been told the best way to find them is walk the rows of a grape
vinyard in the spring, after the ground has been tilled, and just
after a light rain, when the tektites lie glistening on the surface!

Then if you haven't already read up on them, see what the other
branches of the tektite family are all about.

Hello everyone,
I'm new to meteorite hunting and would like to find some place to roam
around near me. I live in northern CA near San Francisco. Does anybody
know of any sites around here that are good for hunting? I'm willing to
drive a few hours of course, but it would be great if there was
something close by. Are there any strewnfields close by? or what is the
nearest?
Thanks!

Hi Robert, all,

I would say that is. Totally legitimate request from your buyer. As a
UK based buyer I will not buy from a seller who uses the global
shipping program. I got caught out accidentally when they first
introduced it as did many people. If it is something I am interested
in I will always now contact the seller and make a request to remove
the global shipping and if they can't accommodate my request then they
lose a sale. Most sellers when asked didn't even realise they were
using the program so Ebay must have not made it an obvious option but
somehow surreptitiously added it!

A total rip off!

My 2 cents anyway :-)

Cheers

Martin

does not include NWA 7325.  The sale will last for 48 hours from the time this 
posts. Pictures of all that I have available are posted on Flickr. All slices 
have been expertly prepared by Marlin Cilz of Montanna Meteorite 
Lab, so you will get great surface to weight ratio on all slices. Regular 
prices will be listed at the top of each page I have a link to and here also. 
Check descriptions, sold items will be marked as such. I have the following 
available:

offer if you see something you like. I'm also willing to do a trade on any of 
this material if you are so inclined. I'm trying to grow my personal collection 
and currently am looking for irons, (slices or complete specimens) of stable 
material (my first choice), let me know what you want to trade, I will consider 
about anything. All specimens will be shipped in an appropriate sized acrylic 
display case or Riker box with ID card. All inquiries off list please. Paypal 
preferred. Thanks for your time. This is getting posted late in my part of the 
world, so if you respond immediately you may not get an answer, but I will 
answer all inquiries in the order that I receive them.

Regards,
Steve

The interview has been cut down to one sentence. Everybody who has dealt with 
the media before knows how these things work.

I actually think his statement is honest and charming - and only hypocrites 
would deny that it is 100% true. We love meteorites - we want to have them. 
Simple! You want to hide this fact from the rest of the world? Good luck...

Stop bitching around and enjoy. These are exciting times, and I am sure there 
will be enough material for all of you.

The Ouadangou L5 Meteorite from Burkina Faso was a tough one, finally ending 
today after receiving it's offical name after a decade of trying to get it 
published.
I went to Burkina Faso to buy Bilanga, and Gao in 1999 and set up a network 
there of people who would search out meteorites and inform me when anything 
fell. 
I have bought over 150 kilograms of Gao meteorites since then, every few months 
a few kilos come in by DHL.
I got a call in Nov 2003 that a meteorite had fallen around 50-60 kilometers 
from Bilanga and I had them send me a sample. I bought it, clearly a gorgeous 
new chondrite fall.
I went back to Burkina Faso and bought more pieces, and sadly all had either 
broken on impact or been smashed by the locals. The largest piece was 2.2 
kilograms, 100% crusted individual, which has been hit with a rock and broke 
into three pieces which fit back together perfectly. It still has grass 
embedded in the crust from impact. That is a very dry area and none of the 
pieces ever saw a drop of water on them. I bought over 4 kilograms and Marcin 
Cimala also got some samples as my meteorite contacts also sent some out to 
him:) So much for loyalty in Africa.
The villages that the stones fell in are little more than locations with two or 
three families and beautiful little huts surrounded by fences to protect the 
family and livestock from lions. 
The stones fell in Batiawo and Lampiayre but the nearest place on a map is 
Ouadangou. Burkina Faso was one of my most interesting places to visit, as it 
was so far off the grid at that time, it was like being in another century.
I have a few hundred grams of fragments, which I can offer for sale, all as 
fresh as the moment they fell, many with crust. 
Private email if you want a piece of this fall.

List,
 
The thought that anyone would think that I'm responsible for harassing the 
kindest, most gentle human being on this list makes me physically ill. I've 
already conveyed my feelings about this to Bernd privately.
 
Gilmer, I'm not sure what you're up to but whatever it, it's sick. Your 
comments and tenor are the epitome of all the things you accuse me of.

Interesting marketing:

Buy Finnish, get meteorite?

...If you want a music album you can pay €6.51 or more, but this one is kind 
of unique: The top five cash-forker-over’s get a piece of an actual meteorite! 
The Shattered Horizon devs really like their space thing, and are handing out 
five – I assume pretty small – pieces of the Sikhote-Alin meteorite that fell 
in Russian in 1947, with display cases and certificates of authenticity. Oh, 
and you get a t-shirt too.

Thanks Larry,

I've been into UFOs from about age 8 or 9. 
Sad thing is even though I have always firmly believed in the highly
advanced visiting and exploring astronauts,ancient or other wise,I have
come to accept the idea that most likely I will never in my short remaining
life time actually be able to see the beyond all doubt evidence come to light. 
I hope I'm wrong.

Hi Ufologists;

Well, rather than sitting around doing nothing about it, we can either 
become leaders or do as followers have since time immorial, sing.

( and my favorite, with the meteorite strike:
http://www.youtube.com/watch?v=ige2YBBJeh4 )

I have come to accept the idea that most likely I will never in my 
short remaining


Well, at least we are rolling in Unclassified Falling Objects ;-)

be able to see the beyond all doubt evidence come to light.

Watching Jodie Foster in Contact can help fill the void!

IMO no need to wait for the light to come to the mountain; we can 
always send some light to vast universe and do something about it.


Humans basically sit home in bed motionless with this responsibility 
except a scant few from whom others assume will provide all direction 
for the species; after all, that 'evidence' we oblige other of 
spacefaring or spacecommunicating cultures to provide to us demands we 
reciprocally act in kind.


Our, that is the efforts of the tiny few, while impressive feats for 
a handful of individuals, in the big picture, are miniscule.


If we are representative of others in the galaxy or local and nearby 
neighborhoods, forget about it..., after going through the alien 
monsters are out to get us phase, we support such lame efforts, if 
indicative of the other creatures out there, we can forget about some 
other intelligence wasting its time or energy to reach here.


Carl Sagan, R.I.P.

Kindest wishes
Doug

Hi all, 

Please see the link below to a webcast of 
Professor Colin Pillingers 
lecture to the Royal Society recently. 

(http://royalsociety.org/events/2012/stones-from-the-sky/) 

Professor Pillinger was the recipient of the Michael Faraday prize in 
recognition of his excellence in communicating science. The lecture is 
called 'Stones from the sky - A heaven sent opportunity to talk about 
science' For those who dont know about Professor Pillinger, here is a 
lowdown: 

'Colin Pillinger is Professor of Planetary Sciences at the 
Open 
University. His research interests include designing unique 
instruments to analyse extraterrestrial samples. During his forty year 
career he has made more than a thousand contributions to scientific 
literature, and also found time to be one of Britain's foremost 
science 
communicators, contributing dozens of popular articles in 
newspapers and 
magazines as well as giving hundreds of public 
lectures. After analysing a 
number of meteorites from Mars and finding 
tantalising evidence of the 
existence of life there, he conceived the 
Beagle 2 mission to land on the 
Red Planet to confirm his discoveries. 
Throughout the project he filled over 
thirty notebooks recording the 
daily happenings which form the basis of his 
autobiographical account 
of the mission - My life on Mars. ' 

Colin 
Pillinger is friends with Derek and Katrina Gray, the owners of 
the Wold 
Cottage and has a particular interest in the Wold Cottage 
meteorite and in 
Sir Edward Topham who was the owner of the land at 
the time the meteorite 
fell. The webcast is an hour long but its worth 
watching, a really good 
intro to the history of the study of 
meteorites from a definite personality 
in the field. 

Cheers 


Martin

Hi Pete, all,

Actually I made a website where I started to upload my own books collection.
But the idea is that anybody can share here their prints too.
http://books.sv-meteorites.com

Will need some time to finish with my books but can make a website working
for everybody later if this idea will be interesting.

Regards,
Sergey

Excellent idea, Gary!

It would be nice if we had a central storage site where this type of
historic data could be saved and easily shared.



I've got the Encyclopedia Britannica Ninth Edition, 1890, kicking around
here somewhere.

I'll follow your lead and try to scan anything relevant and post it.

I think aerolite, bolide, and pallasite entries in old publications would be
interesting, too.

Resending in plaintext format...

Hi All,

Frank and others have expressed interest in potential reentry locations
for UARS later today. Here are my calculations of land possibilities
from
23 September 20:00 UT to 24 September 00:00 UT  (1pm-5pm PDT,
4pm-8pm EDT) and the estimated altitude at the time of each country
overflight:

September 23, 2011

20:05-20:06 Papua/New Guinea 158 km
20:16 New Zealand 169 km
20:38-20:48 Chile/Argentina/Bolivia/Brazil  152 km
21:04 Southern England  159 km
21:06 Denmark  160 km
21:07 Southernmost Sweden 160 km
21:08-21:17 Russia 159 km
21:17-21:25 China 156 km
21:25-21:28 Vietnam 155 km
21:30-21:34 Malaysia/Indonesia  155 km
21:36-21:43 Australia 159-166 km
21:44 Tasmania 167 km
22:12-22:15 Peru  151 km
22:15-22:17 Colombia  150 km
22:17-22:18  Venezuela  150 km
22:35  Scotland  159 km
22:38 Sweden  159 km
22:39-22:48 Russia  159-156 km
22:48-22:49 Afghanistan 155 km
22:49-22:50 Pakistan 155 km
22:50-22:54 India  154 km
23:08-23:09 Southwest tip of Australia  162 km
23:47 Honduras  148 km
23:49 Cuba  149 km
23:50 Bahamas 149 km
23:58 Eastern Newfoundland 154 km

In my opinion, reentry is unlikely during this 4-hour stretch, but I
wanted to get it out there in case the orbital decay rate suddenly
accelerates in the next few hours. I will post predictions for the
more-likely 0:00 UT - 4:00 UT window a little later using the
freshest orbital elements I can get.

Due to the earth's oblateness and UARS' very circular orbit,
reentry is more likely to occur at lower latitudes (30 south to
30 north) than elsewhere.  -Rob

Hello dearest IMCA Members
 
I am searching and considering all possible sources available worldwide
to kinda make out, if it would be an effort to stay awake for some hours
getting an opportunity to watch a possible NASA's UARS re-entry to
earth's atmosphere.
I would be very eager - if not possible to watch it with my own eyes -
even to pursue it's last travel in the internet.
 
Does anybody have a clue of a reliable source in the internet to see
it's momentary heighth and ground track?
I have considered nasa's official site, space weather, heavens above.
But no satisfying source could tell, what's happing in real time.
I cannot believe this. I'm sure there are hundreds of employees sitting
in front of some screens observing the doomed satellite.
 
Kindest regards from Switzerland

Hello List.
I have a Campo del Ceilo end cut, with a small white inclusion ( 1mm) that 
looks like a chondrule.  As far as I know, silicated Campos have black 
silicates, and there are no other visible inclusions in my piece.  As soon as I 
find a place to store photos, I will post a pic, or it can be seen in Facebook 
in the Meteorites group.  Any thoughts would be helpful.
Many thanks,

They sure look like impact craters... “

No they do not look like meteorite craters. First, these featrues
lack the morphology, which would suggest that they might be 
meteorite craters. The majority lack the circular or elliptical outline 
that might characterize an impact crater. The majority of them 
are far to irregular to be candidates for  impact craters. In addition,  
sinkholes can also have nice circular outlines as can be seen in 
the Bottomless Lakes of Bottomless Lakes State Park about 14 
miles southeast of Roswell, New Mexico. 

The Bottomless Lakes are discussed at:

Bottomless Lakes State Park, New Mexico

Kottlowski, F. E., 1979, Bottomless Lakes: New Mexico

Second, if a person looks at the regional topographic maps, 
these features lack any sign of the rim that an impact crater 
would typically have. Finally, geologists have looked
at these features and found them to be classic examples 
of carbonate karst, which are developed in the alternating 
layers of limestone and dolomite of the San Andres 
Formation, which underlies this area.

What one of these sinkholes looks like near the ground
surface can be seen the web page for Fort Stanton Cave,
Lincoln County, New Mexico, at
http://www.fscsp.org/photos/entrance_aerial_view_1200.jpg
http://www.fscsp.org/

The cave is located at lat. 33.50673°, long. -105.4936248°
about 28 miles south of the above area of karst.

I have talked about these features before in:

[meteorite-list] Impact Crater in New Mexico – Part 2
Lincoln County Revisited, January 6, 2009, 
http://six.pairlist.net/pipermail/meteorite-list/2011-January/072231.html

A couple of web pages:

Karst
http://en.wikipedia.org/wiki/Karst

Sinkhole
http://en.wikipedia.org/wiki/Sinkhole

There might be an impact crater or few lost among all of these
sinkholes. However, distinguishing them from the sinkholes
and demonstrating that they are impact craters will take a lot 
a field work. It is certainly something that will be impossible
to do simply from aerial imagery.

Rich Murray wrote:
“Ground samples may reveal evidence of blast and surface 
melting and coating.”

A person can look if they want. I suspect that it such a search
will find a complete absence of any credible evidence “blast 
and surface melting and coating.” 

If a person wants to look for features to investigate as 
possible impact craters, they can check out a reported 
possible impact crater by Skotnicki (2009) within the 
Lincoln 7.5 quadrangle, Lincoln County, New Mexico.

Hi, All,

Is there any particular stone meteorite that has a high content of troilite and 
a low content of free metal?

In “Possible meteorite found in Newport, Arkansas Area”,

McCartney Taylor wrote,

“The reporter confirmed that the confirmation of a meteorwrong 
won't make the paper.”

Unfortunately, this is typical of newspapers in general. Newspapers 
love to write articles about some spectacular claim of either some 
discovery or finding. Then, when the claim is discredited as being 
completely wrong, the newspaper commonly ignores it because 
the truth of the matter is quite boring.

My favorite example is a reported by the now defunct “State Times,”
of Baton Rouge, Louisiana, which reported on January 9, 1951, that 
the bones of a 11-foot Neanderthal Man was found in a gravel pit
in Sicily Island. The Baton Rouge “Morning Advocate” reported on 
January 9, 1951 that  a ”... gravel contractor unearthed parts of a 
human skeleton 35 feet from the surface of the ground...” in a 
Sicily Island gravel pit . As documented in (Arata and Harmann, 
1966), these fossils were later examined by vertebrate 
paleontologists and found to be the bones of a Pleistocene bear.
Nothing appeared in either paper about this finding.

Therefore, a person has to be careful of reports of meteorite
finds and other spectacular discoveries reported in newspaper.

it a meteorite weighing ten tons is estimated that dated back some 
4,000 years.

The location of the crater is reported as latitude 27° 37’ 19.3” South,

Hi List Members

I would just like to echo the views expressed here about the position of Mike 
farmer vis-à-vis Meteorite List membership. I personally would like to see Mike 
re-instated to the list. Our list should be an open forum where people of all 
races, creeds and nationalities can share there love and knowledge of 
meteorites. It should be a place where we can express ourselves freely, but 
responsibly without fear. It should not be a place for belly-aching or airing 
personal grievances, tempting though that is. Yes, I know I have been guilty of 
that myself - mea culpa!

I have met Mike a few times at Ensisheim and Munich and I he has always been 
unfailingly polite and gracious to me. More than that, however, I think that 
the list misses his huge store of knowledge and experience and we can all 
benefit from this. 

If it comes to a vote I put my X beside Mike's name.

Best Wishes from snowy Scotland

[Michael Gilmer]

Hi Mike and Gang,

Facebook is quickly turning into a nexus of meteorite activity.
Collectors, dealers, hunters, scientists, and curious onlookers.
It's also ripe for virtual outreach.  I get questions almost every day
from people who know nothing about meteorites, and they are keen to
learn more.  I try to answer the majority of them.  Of course, there
are also more of the types who send messages like - here is my new
lunar meteorite that I found in Utah, what is it worth and do you want
to buy it? , and the message is accompanied by the obligatory
blurry-photo of a lump of hematite or a terrestrial conglomerate.
But all in all, it's a very good place to network and meet new
people who may later turn into collectors or hunters.  And from a
dealer standpoint, Facebook is now mandatory.  If you are a dealer,
and you do not have an active FB presence, then you are surely losing
potential sales.  Used correctly, FB can be a lucrative marketplace
and it charges zero fees.  :)

Best regards,

MikeG

Abstract at http://arxiv.org/abs/1011.3715
PDF file at http://arxiv.org/pdf/1011.3715v1

Looking at their picture of their hypothesized “crater,”
it looks nothing like either an impact crater or volcanic
crater. The depression that they illustrate lacks any 
indication of a rim that is composed of either impact
ejecta or pyroclastic debris. Also, the bedrock that is
exposed along the rim of the feature lacks any obvious
signs of any deformation. Judging from the photograph,
rock has simply collapsed into the depression instead
of having been ejected from it. 

From all appearances, the depression reported from
Mt Ararat looks like a rather run-of-the-mill collapsed
roof of a lava tube. In their initial stages, such roof
collapses can have a quite circular outline. Also, 
collapsed lava tubes would be common on a volcano
like Mt Ararat. Such as interpretation is consistent
with what can be seen in the photograph.

From a previous post, some examples of collapsed lava tubes are:

In relation to “secret maps” of archaeological sites, E.P. wrote:

Yes, they exist but their use is restricted to professional 
archaeologists. One problem is looting, and even petroglyphs 
have been cut from walls with saws. The other problem is 
vandalism.

E. P. is correct about maps of archaeological sites do exist.
and are kept by specific federal and state agencies that 
have large tracts of land, which they manage and the State 
Historical Office for each of the various states in the United 
States. They are not secret in the sense that it is well 
known that such maps exist. It is just that they can be accessed 
and consulted only by professional archaeologists and other
people, who have an official need to know the location of
known archaeological sites for either research, land
management, firefighting, or other official purposes.

E.P. also stated:

So if you want to photograph petroglyphs, Thomas, the only
way to do it will be with the help of a professional archaeologist.

There is nothing wrong in photographing rock art as long
as nothing is done to the rock art. The problem comes is
when people enhance the rock art, i.e. by outlining it in 
chalk or applying liquids, in order to make it stand out. 
Such actions can very easily and all too often does damage 
the rock art.

You should not apply any substance such as liquid, powder, 
plastic, chalk, cloth, soil, or paper to enhance photography 
or drawing. Despite the ability to enhance photography, 
application of materials to rock art surfaces may forever 
alter its integrity. This has been found to be particularly 
true in radiometric age estimation of rock surfaces.

E.P. noted:

FOIA does not apply.

This is true. For a detailed discussion of this topic see:

Meteorite and meteoroid: New comprehensive definitions

There are more practical reasons that can be used
to select the best upper size cutoff for micrometeorites
and micrometeoroids. Meteorites have long been
recognized as rare, special kinds of rocks. The practice
of naming individual meteorites after the places where
they were found is based on this special status.
Generally, to receive a name, a meteorite must be well
classified and large enough to provide material for
curation and research. Much of the material that
forms meteorites in the inner solar system is relatively
coarse grained. Many chondrites and nearly all
achondrites and iron-rich meteorites have mineral grain
sizes that exceed 100 lm. Although in many cases it is
possible to classify small particles of meteoritic
material at least tentatively, this process is greatly
hindered when the particle size is significantly smaller
than the parental rock’s grain size. To allow for
proper classification, 2 mm is a more useful size cutoff
than 100 lm. In addition, the number of objects that
accrete to the Earth (and other bodies) varies
exponentially with the inverse of mass (e.g., Brown
1960, 1961; Huss 1990; Bland et al. 1996). Single
expeditions to recover micrometeorites have found
thousands of particles in the sub-millimeter size range
(Rochette et al. 2008), but very few that exceed 2 mm.
The 2 mm divide also seems to form an approximate
break between the smallest objects that have
historically been called meteorites and the largest
objects called micrometeorites. This leads to additional
refinements to our definitions:

Micrometeorites are meteorites smaller than 2 mm in
diameter; micrometeoroids are meteoroids smaller
than 2 mm in diameter; objects smaller than 10 lm
are dust particles.

By this definition, IDPs are particles smaller than
10 lm. We are not proposing a lower size limit for IDPs.
Before it impacted the Earth, object 2008 TC3 was
approximately 4 m across and was officially classified as
an asteroid (Jenniskens et al. 2009). It is likely that
when smaller interplanetary objects are observed
telescopically, they will also be called asteroids, even if
they are of sub-meter size. Thus, the boundary between
meteoroids and asteroids is soft and will only shrink
with improved observational capabilities. For the
minimum asteroid size. We thus differ from Beech and
Steel (1995) who suggested a 10 m cutoff between
meteoroids and asteroids.

The Relationship between Meteorites and Meteoroids
It is tempting to include in our definition of
meteorite a statement that meteorites originate as
meteoroids, which, using our modified definition are
natural solid objects moving in space, with a size less that
1 m, but larger than 10 lm; this was done in previous
definitions such as that of McSween (1987). However,
because the Hoba iron meteorite is larger than 1 m
across, it represents a fragment of an asteroid, not a
meteoroid, under our definition of meteoroid. If a mass
of iron 12 m in diameter deriving from an asteroidal
core were to be found on Earth or another celestial
body, it would almost certainly be called a meteorite,
despite the fact that it was too large to have originated
as a meteoroid even under the Beech and Steel (1995)
definition. In addition, the Canyon Diablo iron
meteorites associated with the Barringer (Meteor)
Crater in Arizona, are fragments of an impacting
asteroid that was several tens of meters in diameter
(e.g., Roddy et al. 1980); the Morokweng chondrite may
be a fragment of a kilometer-size asteroid that created
the 70 km Morokweng crater in South Africa (Maier
et al. 2006).

Comets, particularly Jupiter-family comets (JFCs),
could also produce meteorites. A small fraction of JFCs
evolve into near-Earth objects (Levison and Duncan
1997) and could impact main-belt asteroids at relatively
low velocities (approximately 5 km s)1) (Campins and
Swindle 1998). Meteorites could also be derived from
moons around planetary bodies. Lunar meteorites are
well known on Earth, and meteorites derived from
Phobos may impact Mars, especially after

Hello Count and Listers,

Yes it would be intersting to see if something comes of this.You brought up 
something good when you said.  

Particularly in the trading of micro-meteorites and smaller material.

Now is that trading mirco meteorites that have TKW or mirco meteroites from 
taken from bigger meteorites?

Hi Mike:

These are good definitions for things on Earth (meteorites, etc.), but
once one talks about things in orbit around the Sun, this is in the
purview of the IAU and they already have (not so perfect) definitions for
small Solar System bodies.

As I said previously, I would be hard-pressed to call anything larger than
1 meter an asteroid.

I hope you've found genuine fragments of these falls but I have to ask... How 
can you be certain when dealing with highly weathered particles? Please, don't 
make claims like this without irrefutable evidence.

 Subject: [meteorite-list] illinois meteorites found

 hello listees,
 Just wanted to know if anyone has found any more Illinois meteorites from any 
 of the known strewnfields/old find areas.
 I have found a few small Woodbine meteorites 0.5gr, 0.5gr, and 6gr (before 
 cutting)
 I also found a small less than half gram Marengo meteorite. I will probably 
 be keeping these finds in my collection unless I get a good offer for one of 
 them. I plan on getting back out to both places many more times this spring 
 and summer. anyone in the area who would like to hunt with me at either one 
 of these place is more than welcome. The Marengo find was a surprise, I took 
 home many small stones that were really attracted to my magnet, I polished a 
 window in each one and was very surprised to find out one of the smaller 
 stones was part of the meteorite. I have a few photos of the woodbine finds 
 here on the SkyRock Cafe, take a look:

[Galactic Stone Ironworks]

Hi Eric and List,

An interesting little presentation, but I don't agree with some of the
entries on the list.

Let's start from #10 and work our way to the top.

#10 - Allende.  Allende certainly belongs on the list, but I think it
may merit a higher rank than #10.

#9 - Murchison.  This one also belongs on the list, and based on the
science alone, it should rank in the top 3 or top 5.  Murchison has
taught us much and it deserves a higher rank.

#8 - Peekskill.  A fine hammer fall and a great witnessed fall.  I
have no issues with this one, but Murchison should rank higher than
Peekskill.

#7 - Orgueil.  Historical falls from previous centuries opens a whole
new can of worms.  If Orgueil is included, why not L'Aigle?  Or why
not another type fall like Nakhla?  No offense to Orgueil, but this
one is dubious entry on a list that is directed towards the mainstream
lay-public audience.

#6 - ALH 84001.  This one should be #1 in my opinion.  It is the Holy
Grail of meteorites and it contains what many scientists agree is
proof that life once existed on Mars.  As the latest papers have
revealed, the evidence for Martian life contained in this meteorite is
increasingly solid.  I can't think of a more significant meteorite
than this one.

#5 - Sylacauga.  Mrs. Hodges would rank this one as #1.  But is it
more significant than ALH 84001?  In my opinion, no.  And couldn't
they find a photo for it?  A quick Google Image search or Encyclopedia
of Meteorites search reveals several.

#4 - Sikhote Alin.  A great historical fall by all measures.  I have
no issue with this one, other than the obvious one - it shouldn't
outrank ALH-84001.

#3 - Willamette.  Nice choice, but we are now seeing a definite bias
on this list towards iron meteorites.  If Willamette made the list,
why not one (or more) of the Cape York masses?  Heck, Murchison is
certainly more significant than this one.

#2 - Hoba.   The world's biggest iron and it certainly belongs on the
list.  But if Hoba was selected, then why not Canyon Diablo?   The
glaring absence of Canyon Diablo is also made more curious by the
inclusion of Willamette.

#1 - Tunguska! ..a non-meteorite.  This one is an odd choice.
First, it's not a meteorite, it's an impact event.  It was probably
caused by a meteorite or comet, but no meteorites were recovered.  And
if we are going to include an impact event, why not Canyon Diablo?  CD
is more recognizable to the target audience of this list and there are
tons of iron meteorites laying around to show for it.   And if we are
going to include speculative comets like Tunguska, then why not Tagish
Lake?

It's a fun list, but you can tell an intern put it together and not
someone familiar with meteorites.

Best regards and Happy New Year!

Speaking from the ducks point of view. I, as I'm sure many hundreds of others, 
joined this list to learn from the masters as well as pick up info on recent 
falls. Well, I sure got a lesson. I don't expect jack anymore and I assure you 
that I will never share meteorite knowledge of any kind on this list. It's a 
damn shame.

Hello, List, 
I've been thinking... how about a get together for us meteorite enthusiasts, or 
even a meteorite show sometime here on Vancouver Island or the Lower Mainland 
of Southern British Columbia, Canada? 

I don't yet have a passport - which I'll need to get into the US (should be 
getting one soon, though),, and I'd love to get to meet you guys, and get to 
see/handle some of the best out of your meteorite collections! The countryside 
is absolutely gorgeous where I live in the Comox/Courtenay area.. :) 

Maybe we could plan a date which might be good for many of you to come up this 
way? 

Regards

[Sterling K. Webb]

Hi, Dan, Rob, List,

   The key weasel-word in that puzzle is infinite.
An infinite number of anything, no matter how
small, even neutrons, has infinite mass and hence 
exerts infinite gravitational force. 


   Your infinite stack of Earths will collapsr at the
speed of light, having wrapped all space and time
around itself. You are a string of particles stretched
out over light years, with the tip of your nose pressed
against the event horizon at the speed of light where
you feel infinite force, but you are not moving because 
time is standing still for you, and you will stay that 
way forever... in your inertial frame.


   The Newtonian solution is simple. Using the central 
force assumption of Newtonian gravitation (hey! works 
for me!), the gravity you feel is the sum of an infinite series:
1 + (1/3)^2 + (1/5)^2 + (1/7)^2 + (1/9)^2 + (1/11)^2 + 
(1/13)^2 + (1/15)^2 + (1/17)^2 + (1/19)^2 + ... =

1.208722 G's! (approximately, OK?)

   Your problem is that your Earths are too close together.
There is a cosmological solution that allows an infinite
static universe with infinite mass to have a finite and low 
mass density. They're called Charlier universes, but I

never met one. They're awfully empty...

   Experiment is the key to all knowledge. You stack up
an infinite number of Earths, then time falling objects 
with a pendulum, or even better, time the pendulum... 
right in the heart of downtown Gedankenland.

Re: [meteorite-list] (no subject)

[Dan Brumleve]

Sterling,

The solution I had in mind is the Newtonian one (curiously the value
is related to the probability of a random integer being divisible by a
square).  But I don't agree that an infinite number of anything is
necessarily nonsensical...  In this case (an infinite line of planets
with one end), the force is finite everywhere and never much larger
than 1G.  (Alternatively, if we were on the edge of an infinite
half-space packed with planets, the force would be infinite and the
situation much less reasonable, essentially as you described.)

I had never heard of Charlier universes, looks like an applicable
framework, I will read more about it, thanks!

Oh, that theory lies beween the two extremes, the Charlie universe and the
Charliest universe.  Sort of like the strong and weak anthropic principles.

[Paul G. Spears]

Hi, list members:
As a newcomer to the list, let me say that I have been impressed with the
articles and comments I have read already.  I am learning quickly that you
members know your stuff, and that some of you might have a shot at becoming
stand-up comedians if you ever want to change professions.  The repartee and
camaraderie are delightful.  As I read the articles and follow the links, it
strikes me that my only hope of becoming adequately knowledgeable about the
significance and importance of meteorites is submersion in the books and
exposure to the fields.   

Concurrently with cracking the books, I am starting to acquire basic
equipment for my first meteorite hunt.  With the experience most of you
surely have had in using metal detectors, you may have found certain makes
to be superior to others.  Any recommendations you may have for a quality
detector would be greatly appreciated.  Also, I would like to try my hand at
making a one-meter detector if anyone has instructions and specifications
for them, or know who builds them.  Finally, I have a fairly good checklist
of items needed in the field, but if you have a list that you have used to
good advantage, it is likely much better than mine.

I promise I will not burden you with repeated calls for help, but your
geniality encourages me to make this request. It will better insure a proper
start in my retirement to what I expect will be an interesting and worthy
avocation.  

Cordially,

Paul G Spears

Wow - you really are new to the list!  ;-)


 some of you might have a shot at becoming

Paul:
 Welcome to the list.  I normally read quietly, posting something  
every few months when the urge strikes.  Everything you said is true,  
which makes this list one of my favorites.  However, in addition to  
the immense knowledge and profound statements as well as cutting edge  
research and terrific bargains, you will also find an occasional brawl  
resembling a sixth grade schoolyard fight.  I just wanted to give you  
a heads up on what some would call the  downside of this list, but  
which I find sociologically interesting.
Without this caveat it might be similar to finding out as a child that  
your parents weren't perfect, like the first time I saw my normally  
calm dad give some other motorist the finger.  Anyhow, I've been on  
this list for years, and unless I get kicked off for some reason (not  
very likely) I plan to be here for years to come.  I'm sure you'll  
learn a lot and be entertained as well.


George

[rochette]

dear list members

for a research project I am looking for meteorites from the Sahara or 
Dhofar that may have been used by prehistoric man. If you think you 
have such man shaped artefact in your NWAs (or other collection area) 
please contact me off-list; we can expertise it.

regards

Re: [meteorite-list] IMCA subject

[Greg Catterton]

... Ok. 
I would like to say for the record, I am a member of the IMCA.

Taking a step back and looking at the IMCA with a unbiased point of view, I see 
it as a group that has alot of potential and could be a great thing for the 
meteorite hobby.

I do think its more of a dealers club then anything, but I also see it 
working on educational and informative things such as the new Martian site 
(which is really nice!) and even took a big step in getting encyclopedia of 
meteorites site.

No group will ever be perfect or please everyone, but I think the IMCA is doing 
the best they can and are showing continued growth. That is important.

While there is no governing body for meteorites, the IMCA is doing the best 
they can to fill that role the best are able to.

I think more people should look at what the IMCA is doing rather then what they 
are not doing or what people think they should do and most would see that its 
really all in all a good group that has great goals.

 Martin and List,
 
 Well, I just received a veiled death threat from an IMCA
 member for my
 last post.
 
 I can say in all honesty, that I have done hundreds (if not
 over a
 thousand) deals since joining the world of
 meteorites.  Only once did
 someone attempt to scam me, and it was an IMCA member.
 
 IMCA credentials mean zero to me.
 
 Martin, you are one of the good guys and you know I respect
 you.  But
 there are bad apples in the IMCA just like any other large
 group.
 
 Now I am debating whether I am going to contact the
 authorities over
 this death threat I just received.
 
 I guess I better shut my mouth before the IMCA sends a thug
 to my house.
 
 Best regards,
 
 MikeG

  I just opened the ebay-site, searched for meteori*,
  got 1681 results.
  
  Please show me those auctions from IMCA-members, where
 fakes, not authentic
  or at least doubtful material (regarding the
 authenticity) are offered.
  
  And then list me those auctions from non-IMCA-members,
 where fakes, non
  authentic and doubtful material is offered.
  
  IMCA was founded to make meteorite trades safer for
 all.
  The result of your comparision will be, I dare to
 foresee, quite convincing,
  that that IMCA-thing already could be called quite a
 success.
  
  I guess, if you'll search for Sideroli and nandan,
 meteori* +sphere
  and tibet +meteori* ect. you will directly obtain
 your first 20-50 fakes,
  ..to make it a little bit easier.
  
  Hmm those meteoritic carbonados currently en vogue,
 I just can found only
  2 offered. Together 50 k$. a nice sum to go
 shopping for real
  meteorites.
  
  To lazy (US-ebay is working so slowly on my computer
 since weeks?) to check
  how many tektites currently are offered there to the
 layman to have
  originated from the Moon...
  
  That's what IMCA mainly is about.
  
  And I'm so old, that I know the times before IMCA
 and how the situation
  was there, where everyone could sell any stone from
 his garden as meteorite,
  with the rookie, the laypeople, the unexperienced
 having zero possibility to
  know something about authenticity and having zero
 guidelines.
  Now his chances to be ripped off are definitely lower,
 when he looks for the
  IMCA-labels.
  
  (And I have by far less people to console in my
 practise, who bought crap as
  meteorites, than the years before).
  
  I for myself am astonished, how few complaints about
 alleged misdemeanour or
  fraud of IMCA-members reach IMCA.
  Remember IMCA is statuably obligated to proof each and
 every case reported.
  And in turn, if nobody complains, IMCA can't know the
 case.
  Remember that instrument is available for ALL, for
 non-members too, as long
  as the wrongdoing party is a member.
  Do you know any similar service in the meteoritic
 field?
  
  Hmm perhaps another, more empiric thought:
  Why do so many dealers, collector-dealers, collectors
 and those, who
  frequently or sporadically trade, sell, swap
 meteorites join IMCA,
  if that club is only a joke?
  Nobody urges them to do that, it's there free will and
 it even costs them 20
  bucks and makes their transactions more difficult, if
 they obey the code of
  ethics.
  
  So why?
  If we let aside all that pathetic stuff about

[Suzanne and Jim]

hi all and sundry 


need some advice,

I am trying to determine the nature of the orthorhombic-like opaque red/brown 
crystals I have seen in a slice I am considering having analyzed.

I cannot find any similar images on the web or in text books.

I had first thought the stone looked a bit like some lunars I have seen but on 
creating my second thinsection from  it I noticed crystal shapes that that I 
thought put a dampener  on possible lunar origins.

When ilmenite is weathered does it turn reddish brown?


please look at 

http://members.optusnet.com.au/jimcmurray

the last few slides show a couple of these crystal shapes

anybody have any ideas and perhaps point me to some images of similar features.

btw this is NOT a NWA .

Jim
