[meteorite-list] Cerro Mesa info

[Laurence Garvie via Meteorite-list]

Regarding Cerro Mesa, I found the following on ResearchGate

https://www.researchgate.net/publication/281281502_La_condrita_ordinaria_Cerro_Mesa_en_el_limite_de_la_clasificacion_entre_dos_grupos

So, it looks like the classification work is done, but just not submitted to 
the NomCom.

best,
Laurence

Hey all. I've been lurking for a while, but now I have a question for you all.

Back in 2008 I acquired some Cerro Mesa (Provisional) L6.  At this
time, it still has not shown up in the MetBul.   Does anyone know what
happened?

Best of luck in your quest to find what waiting list or dusty shelf Cerro 
Mesa has landed upon.
   Another one of interest for me is Breja. Reportedly a Fall!

[meteorite-list] Need Sutter's Mill please

[Laurence Garvie via Meteorite-list]

Dear Meteorite collectors,

I am in the process of working on the bulk mineralogy of Sutter’s Mill as 
determined by powder x-ray diffraction. I have run several samples now, 
including the pre-rain SM3, and found some interesting minerals. My big 
interest is in the clay mineralogy, the quantity and type in each sample I am 
arguing reflects degree of pre-terrestrial heating. I now have a relatively 
good dataset of samples (SM3,41,38,49,65,8,6,12,53), but would dearly like to 
run a few more. There seems to be some gaps in the data with regards to clay 
content and hence heating. I don’t know yet whether this gap reflects the fact 
that I have not looked at enough samples, or is real and is telling us that 
there are two groups of Sutter’s Mill - clay rich (mildly heated), and clay 
poor (heated to high temperature).

So, I am looking for small pieces of samples for my research. Ideally, I am 
looking for donations of small fragments - 100 mg would be perfect, though I 
can still work on samples in the 20 mg range.

If anyone has samples available, then please feel free to email me.

Thanks

Laurence

[meteorite-list] Lunars for peanuts

[Laurence Garvie via Meteorite-list]

I know of relatively large lunars that are being offered at around $50/g and 
not being bought (1 kg stones). There seem to be a plethora of Lunars and 
Martians. Nice shergottites could be had from the 2015 Tucson show for around 
$80/g. In the last year, the NomCom has approved 35 lunars (over 16 kg) and 19 
martians (around 2 kg).

Personally, given the huge numbers of Lunars being classified, I expect the 
price to be at the $50/g range or lower in the near future - somewhere in the 
range of the HEDS.

Laurence

 Hello Listers
 
 I am starting to see a trend with Lunar and Martian meteorites, but
 especial with Lunar's. Some can be had for $300 per gram or less, or
 some times on ebay you can get a steal on some of the 1g plus sizes for
 less then $400 a gram. But again at the sub gram leave the price is
 still in the high $500 to $800 per gram which is expected at that size. 
 
 My question is, is there new product on the market or has planataries
 shifted in value?

 Hi Shawn,
 
 I think most of what we are seeing is supply and demand at work.  As
 time goes on, more and more planetaries are coming out of the hot
 deserts, especially the NWA DCA.  In recent months, we have seen over
 a dozen new planetaries (including several lunars) that have been
 approved in the Met Bulletin.
 
 New collectors are coming in to the hobby on a regular basis, but the
 supply of planetaries available to these collectors has stayed steady
 or increased.  Old offerings are absorbed into collections and vanish
 from the open market, but they are replaced with numerous new
 offerings that are being sold by an ever-increasing number of dealers.
 
 In the past, the majority of planetaries were held by a
 relatively-small group of veteran dealers.  Now, there are many
 middle/moderate-size dealers who are offering lunars and Martians.
 
 In order to be competitive, dealers need to better control the
 supply/market (not likely) or lower prices to attract buyers to these
 new planetaries - many of which are not that remarkable in comparison
 to previous offerings.   For every new Nakhlite or Black Beauty, there
 are a dozen new (sometimes unpaired) shergottites hitting the
 market.
 
 I won't mention names, but there are a couple of big collector/dealers
 who are buying up multiple planetary masses in recent years and the
 majority of that material does not appear to have hit the open market
 yet.  If that material is ever released into the market, it would
 depress the asking prices even further.
 
 Best regards,
 
 MikeG

Re: [meteorite-list] Met Bulletin Update: Sahara 00293

[Laurence Garvie via Meteorite-list]

Crystyl is a grad student in the School of Earth and Space Exploration at ASU. 
She is studying shock phases in meteorites, and by chance Sah 00293 has 
something very interesting in it (you can look up her LPSC abstract which will 
be online in a few weeks). In order for her LPSC abstract to be accepted, she 
had to first classify and then get the meteorite accepted by the NomCom.

 Hi Bulletin Watchers,
 
 There is one new approval. I find it curious. It is an old Sahara OC
 found by Mr. Labenne fifteen years ago (2000). Crystylynda Fudge was
 the classifier. I have never heard this name before. I am just curious
 why this meteorite suddenly appeared out of obscurity to be approved
 today.

 with trace native Cu. Evidence of minor planar deformation features in
 olivine. Ubiquitous opaque shock melt veins and associated dark blue
 ringwoodite and green wadsleyite.

[meteorite-list] Cutting Sutter's Mill

[Laurence Garvie]

Personally, I see nothing wrong with cutting Sutter's Mill. We (as in the 
scientific community) now have lots of stones and sliced pieces are needed for 
thin sections, polished mounts, etc. The TKW is well over 300 g - compare this 
with the really rare carbonaceous chondrites (e.g., Revelstoke - 1 g; Tonk - 
7.7 g; Maribo - 25.8 g; Santa Cruz - 60 g; Crescent - 78.4 g etc). 

I have cut two stones. Both were cut dry, very slowly, and with a super thin 
wafering blade. I have collected the cutting dust so the cut loss is zero. Even 
so, both stones broke while about 3/4 the way through the stone. Anyway, in 
hand specimen, the cut and polished faces are not particularly interesting 
looking - just black with a few while chondrules and CAIs, and sparse 
metal/troilite grains.

 Well Mike,
 
 If I can add a measly 10% to the body of knowledge of this meteorite, by 
 sacrificing one little stone (heck if I can help add 1/10 of 1%) I think that 
 would be great.
 
 My guess is that a lot of these stones that are going into both institutional 
 and private collections won't ever be broken up much less in a non 
 contaminated way and they will sit as whole stones behind glass for 
 thousands of years.
 
 Nothing wrong with that at all.
 
 I'm just saying that one might gather from your post below that you were 
 implying in a self righteous manner that I might have done something horribly 
 wrong by having one of these (already contaminated) meteorites sliced?

[meteorite-list] Cutting Sutter's Mill

[Laurence Garvie]

Personally, I see nothing wrong with cutting Sutter's Mill. We (as in the 
scientific community) now have lots of stones and sliced pieces are needed for 
thin sections, polished mounts, etc. The TKW is well over 300 g - compare this 
with the really rare carbonaceous chondrites (e.g., Revelstoke - 1 g; Tonk - 
7.7 g; Maribo - 25.8 g; Santa Cruz - 60 g; Crescent - 78.4 g etc). 

I have cut two stones. Both were cut dry, very slowly, and with a super thin 
wafering blade. I have collected the cutting dust so the cut loss is zero. Even 
so, both stones broke while about 3/4 the way through the stone. Anyway, in 
hand specimen, the cut and polished faces are not particularly interesting 
looking - just black with a few while chondrules and CAIs, and sparse 
metal/troilite grains.

 Well Mike,
 
 If I can add a measly 10% to the body of knowledge of this meteorite, by 
 sacrificing one little stone (heck if I can help add 1/10 of 1%) I think that 
 would be great.
 
 My guess is that a lot of these stones that are going into both institutional 
 and private collections won't ever be broken up much less in a non 
 contaminated way and they will sit as whole stones behind glass for 
 thousands of years.
 
 Nothing wrong with that at all.
 
 I'm just saying that one might gather from your post below that you were 
 implying in a self righteous manner that I might have done something horribly 
 wrong by having one of these (already contaminated) meteorites sliced?
 
 Of course there are opportunity costs in any course of action one takes.  The

[meteorite-list] looking for Franconia

[Laurence Garvie]

Dear Franconia collectors and hunters,

I have recently become interested in the Franconia meteorites. There are some 
real mysteries that need to be sorted out for this area, such as the 
relationship between Franconia and the other H ordinary chondrites and irons 
from this same area. 

I am fortunate to be working closely with Jim Woodell and Ruben Garcia on this 
project and through them I have acquired some interesting pieces.

However, I am looking for pieces of Franconia with metal blebs or significant 
metal concentrations. I have seen some interesting web photos of cut pieces of 
Franconia with cm-sized metal blebs, but so far I do not have such a piece for 
study. 

So, if anyone has a Franconia with a large metal nodule that they would like to 
lend/sell/trade to me, then please email me at lgar...@asu.edu

Feel free to send photos.

Thanks

[meteorite-list] Color of OC's by Staining or by Trace Elements

[Laurence Garvie]

Just a quick reply to this subject as it could become lengthy and involved.

The primary coloring agent in meteorites is Fe2+ for fresh meteorites and Fe3+ 
for weathered ones (BTW - shocked meteorites can be black - see below). There 
is also Fe0, which is in the metal. 

When a few percent of Fe2+ is present, then minerals such as pyroxenes and 
olivines are usually green to greenish-yellow. A good example of Fe2+ coloring 
is in Johnstown, which is composed primarily of green pyroxene. 

If very little Fe2+ is present then pyroxene is normally white/clear as in the 
aubrites, such as Bishopville. 

In our oxidizing atmosphere, the metals in meteorites rust, producing Fe3+ 
-bearing oxides/oxyhydroxides. These rust minerals stain the meteorite and can 
range in color from yellow-orange-red-purple-brown-black.

Shocked meteorites can be black. A great comparison is between the two know 
chassignites - Chassigny and NWA2737, both of which have similar mineralogies. 
Fresh Chassigny is yellowish green - the color is caused by Fe2+ in the 
olivine. Yet, NWA2737 is black. The black color is caused by abundant 5 to 15 
nanometer-sized iron-nickel droplets in the olivine, which are strongly 
absorbing in the visible and near-IR region of the spectrum. These droplets are 
formed during intense shock events.

Practically everything you ever wanted to know about color in minerals can be 
found at Prof. Rossman's site at http://minerals.gps.caltech.edu/

 Hi Greg and List,
 
 Great question Greg.  I'm curious to hear what the experts have to say.
 
 Some OC's start out as white or light-grey - like some LL6 types.
 That is why some LL6 meteorites are mistaken for lunars or eucrites -
 because they lack chondrules and have that whitish color.
 
 Best regards,
 
 MikeG

 Hi List:
 I hope everyone is well.
 I have a question regarding the 'color' of OC's through staining by some
 mineral influx or by oxidation.  It appears most fresh OC's start out as a
 light beige or tan color; then through time the metal rusts and they often
 turn yellowish, orange, or brownish - this make sense.  My questions is
 this:
 What other colors can they become, blue or green?  What element(s) result in
 different colors?  What different weathering processes are involved?
 The reason I ask is because I have a weathered meteorite that is dark green
 in color; it looks like jade and I have not seen any like this one before.
 I have also and seen OC's with a 'black' color, what causes that?
 Thanks,
 Greg S.

[meteorite-list] meteorite classification costs

[Laurence Garvie]

The question comes up from time to time about the cost of classifying a 
meteorite and also regarding turn around time.

The actual cost varies significantly depending on the type of meteorite. 

For example, base cost for an equilibrated OC 
1) thin section $30 (the cheapest part of the process)
2) two hours on a microprobe $200 (machine costs at cheap university rates and 
not including the time to set up the probe which can take several hours)
3) operator cost are more difficult to assess but I would imagine their two 
hours on the probe plus another hour or two of putting the data together and 
submitting it - so lets say another $200 minimum
So around $500.

Now for an unquilibrated OC (since you need a good spread of Cr2O3 data) I 
would say at least eight hours on the probe so over $1000

Now if you need oxygen isotopes, then this by itself could easily cost $1000 
(plus the $1000 for the rest of classification). But good luck finding a lab to 
run the 16,17,18O isotopes. Most isotope labs only run 16O and 18O.


In reality, the true costs are not passed on to the owner of the stone, but 
instead are borne by the institute undertaking the work.  Some classifiers will 
charge a nominal fee to cover probe time, but again that is a small fraction of 
what it would cost if you wanted probe work done in a lab at industrial rates.


Turn around time - days to years depending on how interesting the  stone is.

 but it has a place on any meteorite collector's shelf.
 
 I particularly like the glossy pages with wonderful pictures.  The pictures
 of Geoff and Geoff and Steve hunting meteorites and the meteorites are
 fantastic.  Excellent photography and book amounts to a how-to for hunting
 meteorites.
 
 If you haven't purchased one, do so.  You won't regret it.
 
 Thanks Geoff.  Very nice book.

Re: [meteorite-list] Clay meteorites?

Using the definition that clays are phyllosilicate minerals with a grain size 
of 2 microns, then we already have lots of clay meteorites. The clay contents 
of the matrices of the CM2 meteorites is on the order of 70 to 80 vol% (see 
K.T. Howard, G.K. Benedix, P.A. Bland a,b, G. Cressey (2009) Modal mineralogy 
of CM2 chondrites by X-ray diffraction (PSD-XRD). Part 1: Total phyllosilicate 
abundance and the degree of aqueous alteration. Geochimica et Cosmochimica 
Acta, vol 73, 4576-4589) and Orgueil around 80 vols % clay composed of 
serpentine and serpentine-saponite (see Philip A. BLAND, Gordon CRESSEY, and

 Pallas is second largest asteroid [by volume], and we don't know much about

[meteorite-list] Ultraviolet space rocks

[Laurence Garvie]

I took the picture displayed in Rocks from Space Picture of the Day dated 
September 29, 2009.

I used a UV led flashlight with the primary output around 380nm.

Most minerals in meteorites do not fluoresce under UV light because of their 
high Fe content. The Fe quenches the fluorescence. The aubrites formed under 
low fO2 conditions and hence the pyroxenes have very low Fe (typically 350 ppm 
FeO).  If I remember correctly, the color of the fluorescence may have 
something to do with trace amounts of Mn.

 Hi All,
 
 I notice that the Rocks from Space Picture of the Day, dated about a
 year ago, September 29, 2009, features an unusually remarkable glowing
 fluorescent meteorite.  It's described as an 11.1 g piece of Norton
 County (ASU#523) where The large enstatite crystals fluoresce bright
 yellow.  Quite an eyeful.
 
 This is an oddball meteorite, I'm guessing, as I haven't seen pictures of
 any other meteorites displaying fluorescent color values.  Does this bode
 well for other fluorescent meteorites being found?  I mean, are the
 scientists really looking and checking for fluorescent color values in
 meteorites on a systematic basis?
 
 If not, they may be missing the boat.
 
 If you look closely at this picture you may be able to detect, as I do,
 that there apparently are other possible fluorescent color values
 happening, as well.  I am referring to the noticable blue/green colored
 fluoresent values below and to the right of the yellow colored enstatite
 and to the upper left of the enstatite area, also.
 
 To my understanding, these may indicate additional minerals with other
 fluorescent color values reacting to utlraviolet light, too.
 
 It's unfortunate that the person who took this picture did not take the
 time and spend the effort to look carefully at their resulting picture.
 
 I wonder what wavelength ultraviolet was used, although I guess it was
 probably shortwave.  If so, they may not have exposed the specimen to
 midwave and longwave ultraviolet wavelengths, as well, consequently
 denying themselves (and the rest of us!) valuable ultraviolet reactive
 fluorescent color value information.
 
 Is this simply a situation of sloppy science rearing it's ugly head?
 
 Or does it indicate that ignorance is truly bliss, after all?
 
 Yours for the light,

[meteorite-list] ASU suspends public meteorite identification program

[Laurence Garvie]

The public Meteorite Identification Program hosted by the Center for Meteorite 
Studies at Arizona State University has been suspended effective immediately 
(September 8th, 2010). We have had to suspend the program due to the 
substantial recent rise in demand as well as budget constraints and staff 
limitations. We are working on a more outreach-oriented program directed toward 
school-aged children, which we hope to have up and running in the near future. 

Sincerely,

Dr. Laurence Garvie

[meteorite-list] Las Canas achondrite

[Laurence Garvie]

I am trying to find some information on a meteorite we have in our collection. 
I have a 0.3 g crusted fragment of an achondrite, possibly eucrite, and old 
label that reads Las Canas, St. Andras, Cuba, 2. Oct 1844.

Is this a valid meteorite, fall??

Thanks

[meteorite-list] Fireball Temperature?

[Laurence Garvie]

I just had a quick look at the paper by Popova, Meteoroid Ablation  
models (2004) Earth, Moon, and Planets, vol. 95, 303-319, and their  
spectral data from meteorites indicate that the brightness  
temperatures of the vapor are around 4000-6000K.

[meteorite-list] stinky meteorite

[Laurence Garvie]

A while back I was dry cutting (slowly with a thin low-density diamond  
blade) a piece of Indarch, which produced a rather disagreeable odour.  
I put the smell down to the reaction of the finely powdered air- 
sensitive minerals such as oldhamite and niningerite with the moisture  
in the air.

[meteorite-list] black diamonds from Canyon Diablo

[Laurence Garvie]

For those who are interested, my colleague and I recently worked on  
the black diamonds from the Canyon Diablo meteorite. The abstract can  
be downloaded  at


www.lpi.usra.edu/meetings/lpsc2009/pdf/1346.pdf

In summary, they are not pure diamond but a combination of diamond,  
lonsdaleite (hexagonal diamond), and graphite. We also found areas  
that were neither diamond or lonsdaleite.

[meteorite-list] price of meteorites

[Laurence Garvie]

I was looking through some of Niningers old letters from the 1930s and  
found that he bought the Springwater pallasite for 1US dollar per  
pound of meteorite. Taking into account inflation that amounts to  
about 12US dollars per pound today. Compare this with current prices  
which are running near 11,400US dollars per pound.

[meteorite-list] samples

[Laurence Garvie]

The other problem that clogs the system is the huge number of non- 
meteorites that get sent for classification. Of the ca. 500 to 1000  
meteorites that get sent per year to Arizona State University by the  
public for validation, only about 5 or 10 are actually meteorites.  
While most are obviously not meteorites, it is till time consuming to  
open each packet, examine the material, write a small blurb about why  
it is not a meteorite, pack it up again, and send it back to the  
owner. Of the actual meteorites, most are small weathered OCs.

I am processing some Uruacu and some of the pieces have huge shiny

Does anyone know what these are, you can see a lot of them in this  
354 gram

Does anyone have any tips on photographing this material.  It  
doesn't have a
lot of contrast but the etch looks 1000% better then what this  
image shows:


http://i131.photobucket.com/albums/p298/BobaDebt/Uruacu/ 
354grSlice2.jpg


I have tried shooting it from various angles, with and with out flash,
inside, outside, nothing seems to really capture the look of the etch







Speaking of the etch, does anyone have any ideas on how to get more
contrast, I have tried a variety of Nitric Acid and Ferric Chloride
Solutions and I have even tried various combination of both.

If anyone can offer any help it would be greatly appreciated.

Thanks

[meteorite-list] Looking for desert varnish

[Laurence Garvie]

I am studying the mineralogy and chemistry of desert varnish from the  
southwestern USA. I am eager to study similar varnish from deserts  
world-wide. The varnish that I am interested in forms on rocks from  
desert pavements and is typically dark black, sometimes shiny. Note,  
I am not particularly interested in the red varnish, which has a  
different mineralogy and chemistry from the black varnish.



So, does anyone have any meteorwrongs from known locations from  
Africa, Middle East, Mongolia?, or Australia that they are willing to  
part with. I do not need large samples, small pebbles or cobbles are  
big enough. Important though is a known location for the sample.


If anyone has samples they are willing to part with, then please  
email me privately.


Thank you in advance.

Re: [meteorite-list] Black diamonds= supernova origin?

[Laurence Garvie]

I have had a quick look at the paper that proposes that black diamonds  
are interstellar. The authors have made some interesting measurements  
and it is true that the carbonado diamonds have long puzzeled  
scientists. I actually have several large carbonado stones on my desk  
and have meant to study them for some time. The part of the paper that  
is rather vague is the notion of the carbonado as forming in an  
interstellar environment - the authors mention white dwarfs composed of  
modified diamond and planets composed of concentric rings of diamond.  
Unless the C, H, and N isotopes of the carbonados are really strange I  
prefer to think of them of having formed terrestrially or possibly some  
early parent body collision process during the early history of our  
solar system.

By the way, just to clarify, diamonds are common in many meteorites  
including carbonaceous chondrites, ureilites, and just about any  
meteorite that contains carbon and has been shocked.

Laurence

 ET Gems: Black Diamonds Come from Outer Space

 By Jeanna Bryner
 LiveScience Staff Writer
 posted: 08 January 2007
 05:42 pm ET



 If you?re looking for a space-age way to propose marriage, a  
 black-diamond ring
 might be the way to go.

 Long baffled by their origin, scientists now have evidence that these
 charcoal-colored gems [image] formed in outer space.

 Stephen Haggerty and Jozsef Garai, both of Florida International  
 University,
 analyzed the hydrogen in black diamond samples using infrared-detection
 instruments at the Brookhaven National Laboratory and found that the  
 quantity
 indicated that the mineral formed in a supernova explosion.

 Also called carbonado diamonds, meaning ?burned? or ?carbonized? in  
 Portuguese,
 black diamonds defy mineral-making rules and are neverfound in the  
 world?s
 mining fields  where the clear and classic variety typically resides.

 Conventional diamonds form hundreds of miles beneath the Earth?s  
 surface, where
 high pressure and heat turn carbon into diamonds

 Volcanic blasts send the gems in a short amount of time to the surface  
 where
 they can be mined. This process preserves the unique crystal  
 structure that
 makes diamonds the hardest natural material known, said Sonia  
 Esperanca of the
 National Science Foundation. She was not involved in the research.

 Since 1900, about 600 tons of conventional diamonds have been traded.  
 Black
 diamonds reside in certain geologic formations in Brazil and the  
 Central African
 Republic.

 Haggerty has suggested, in the past, that black diamonds might have  
 rained down
 on Earth inside meteorites 

[meteorite-list] pyrite not magnetic

[Laurence Garvie]

Pyrite, as in FeS2 is not ferromagnetic but diamagnetic. Upon heating  
pyrite oxidizes and produces magnetic products (oxides). In contrast,  
CoS2 with the pyrite structure is ferromagnetic. Anyway, pyrite is  
rarely found in meteorites.
