Re: [meteorite-list] meteorite-list] List is getting torpid

2014-03-11 Thread Peter Scherff
Hi,
A simple way to make the list more informative would be if people when
responding to posts of a general nature would reply to all. Whenever I ask a
question about half of the responses that I receive are directed only to me.
Don't get me wrong, I appreciate the responses. However I think that the
whole list should have the benefit of them, unless there is a good reason
not to include the general meteorite community.

Thanks,

Peter

Well said Jim and I'll give you a like.  Traditions are changing. I was very
adamant at first and held back from social media but it was the only way
that I could keep in contact with my family. And yes, the days of forums are
slowly dying unless you incorporate them into the social media, as Nugget
Shooters has as well as many others.

Just my $1.50AU

 Hi all!

 I have posted specific and not so specific meteorite related questions 
 here where Melinda Hutson, Alan Rubin and Carl Agee have answered my 
 questions privately and here on this list.  I absolutely appreciate 
 this.
 I do this because I do have questions and I want good answers, which I 
 receive here.
 I have received private emails complementing this effort to involve 
 listees in my search for better understanding.

 So if you are a complainer, suck it up and quit your belly aching and 
 get over it.

 You are either part of the solution or part of the problem.

 I do admit, FB is great for sharing my Meteorite related stuff. My 
 page is mostly about meteorite stuff which I am actively and 
 constantly involved with.  And, there is not one single Ad on there 
 for meteorites!
 Many of you are there and I appreciate that and hope you enjoy my sharing.
 That said, many or most all of the meteorite related lists have died 
 out and nothing much is being posted...so it is not just this list.

 I completely disagree that any list should direct what topic is to be 
 discussed for any given time as someone suggested.

 So I switch you back to your normally scheduled activities and I will 
 go back to watching epoxy mounts of green beach sand and NWA 
 7831/Kilbourne hole green stuff cure thanks to Gary and Greg!

 Best to all!

[meteorite-list] Shooting Pictures of Meteorites??

2014-03-11 Thread Jim Wooddell

Hi all!

So, I have a cheapy 12mp Nikon CoolPix camera and can take some decent 
macro pictures of small objects.  I use a homemade poor
man's light box, made from a cardboard box and crumpled aluminum foil 
and a light.  This combo works well for me with the exception of

some wide angle issues because of the limitations of the camera.
My Son, Dusty, has thousands upon thousands of dollars of Nikon high end 
camera gear and can take shots that make my low end stuff look
really bad!  Instead of a light box, which he is not use to and does not 
like, he uses a tripod and a huge light ring that his camera shoots thru

with radio controlled flash.

So, I am curious and would like to know what you folks are using for 
your pictures???  I sure see some fantastic pictures.

Hi Jim,

Good topic :-)

I use a Nikon DSLR and macro lens mostly or a Fujifilm bridge camera.
For me though it's not about the camera but the lighting. Although i
like shooting in daylight i tend to use artificial lighting to be able
to easily reproduce my results. I use a pop up light tent which is
basically a white fabric cube with one face of the cube open to shoot
through. I then use a fibre optic light with intensity control as a
single source light. Prior to this i used a single lightbulb with
similar results :-)

Works well for me :-)

Hello!  Low Budget plan..
Jim,  You have a great little camera, I bought the same one.  I then got on 
EBay and bought a 24 fabric light box with 4 silk backgrounds, 2 high output 
lamps and a small camera mount.  All in a kit with free shipping,
for $35.  I'm using it to catalog my collection.  Fun!!

[meteorite-list] Mars Reconnaissance Orbiter Safe After Unplanned Computer Swap

2014-03-11 Thread Ron Baalke

http://www.jpl.nasa.gov/news/news.php?release=2014-078  

NASA Orbiter Safe After Unplanned Computer Swap
Jet Propulsion Laboratory
March 11, 2014

NASA's long-lived Mars Reconnaissance Orbiter put itself into a
precautionary safe standby mode March 9 after an unscheduled swap from
one main computer to another. The mission's ground team has begun
restoring the spacecraft to full operations.

The spacecraft is healthy, in communication and fully powered, said
Mars Reconnaissance Orbiter Project Manager Dan Johnston of NASA's Jet
Propulsion Laboratory, Pasadena, Calif. We have stepped up the
communication data rate, and we plan to have the spacecraft back to full
operations within a few days.

Mars Reconnaissance Orbiter's science observations and its relaying of
communications from NASA's two active Mars rovers have been suspended.
The rovers continue to use NASA's Mars Odyssey orbiter as a
communications relay.

Entry into safe mode is the prescribed response by a spacecraft when it
detects conditions outside the range of normal expectations. Mars
Reconnaissance Orbiter has experienced unplanned computer swaps
triggering safe-mode entry four times previously, most recently in
November 2011. The root cause of the previous events has not been
determined. The spacecraft has also experienced safe-mode entries that
have not involved computer swaps.

Unlike any previous safe-mode entries experienced in this mission, the
March 9 event included a swap to a redundant radio transponder on the
orbiter. While the mission resumes operations with this transponder,
engineers are investigating the status of the one that is now out of
service.

NASA's Mars Reconnaissance Orbiter entered orbit around Mars eight years
ago, on March 10, 2006. Since then, it has returned more data than all
other past and current interplanetary missions combined. The mission met
all its science goals in a two-year primary science phase. Three
extensions, the latest beginning in 2012, have added to the science
returns. The longevity of the mission has given researchers tools to
study seasonal and longer-term changes on the Red Planet.

JPL, a division of the California Institute of Technology, Pasadena,
manages the Mars Reconnaissance Orbiter for NASA's Science Mission
Directorate, Washington. Lockheed Martin Space Systems, Denver, built
the orbiter and collaborates with JPL to operate it. For more
information about the Mars Reconnaissance Orbiter, visit

[meteorite-list] IAU Concerns and Considerations with the Naming of Mars Craters

2014-03-11 Thread Ron Baalke

http://www.iau.org/public_press/news/detail/iau1402/  

Concerns and Considerations with the Naming of Mars Craters
IAU News Release
11 March 2014, Paris

Recently initiatives that capitalise on the public's interest in space
and astronomy have proliferated, some putting a price tag on naming
space objects and their features, such as Mars craters. The
International Astronomical Union (IAU) would like to emphasise that such
initiatives go against the spirit of free and equal access to space, as
well as against internationally recognised standards. Hence no purchased
names can ever be used on official maps and globes. The IAU encourages
the public to become involved in the naming process of space objects and
their features by following the officially recognised (and free) methods.

In order to make sure that all scientists, educators and the general
public speak the same language, astronomers from the International
Astronomical Union have agreed on common standards for naming space
objects, features or phenomena so that they can be easily located,
described, and discussed. For instance, features on a given planet or
satellite receive names chosen from a particular theme. Only those
features that are deemed to be of significance to science are given a
name by the community, thus leaving other features to be named by future
generations.

Although the present rules are that the general public cannot request
that a particular feature is named,  they can do so following a public
invitation from a space agency or from the discoverers. This was the
case for NASA's Magellan Venus mapping mission launched in 1989: the 
public was invited to offer names of women who had made outstanding or 
fundamental contributions to their fields, for the names of Venusian craters.

A more recent example was the naming of the two most recently discovered
satellites of Pluto in 2013, which was the result of a public vote. The
selected names were approved
http://iau.org/public_press/news/detail/iau1303/ in cooperation with
the IAU and free and equal participation was offered to the general
public. For Mars craters today, only their discoverers, the space
agencies, may take the initiative to involve the public in the naming
process, in cooperation with the IAU and following international
regulations.

In 1919, when the IAU was founded, it was given the official mission
to establish internationally recognised planet and satellite nomenclature. 
The objective at the time was to standardise the various confusing systems
of nomenclature for the Moon that were then in use. Since that time, the
IAU has succeeded in constructing a single, reliable, official catalogue
of surface feature names, thus enabling successful international public
and scientific communication. The IAU played a key role in getting the
USSR and the USA to agree on naming rules for lunar features
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.../19780004017_1978004017.pdf
even during the space race of the sixties.

Today, the IAU Working Group for Planetary System Nomenclature (WGPSN),
representing the worldwide astronomical community, provides a unique
system of official names for Solar System objects (planetary surface
features, natural satellites, dwarf planets, and planetary rings) for
the benefit of the international science community, educators, and the
general public. To read more about the naming of objects in space,
please visit the IAU theme Naming Astronomical Objects
http://www.iau.org/public/naming/.

The IAU encourages entities wishing to promote space science and
exploration to follow these internationally accepted rules and explain
them as part of their space education and exploration programmes.

More information

The IAU is an international astronomical organisation of more than 10
000 professional astronomers from more than 90 countries. Its mission is
to promote and safeguard the science of astronomy in all its aspects
through international cooperation. The IAU also serves as the
internationally recognised authority for assigning designations to
celestial bodies and their surface features.

[meteorite-list] Why isn't Mreira classified as a Fall?

2014-03-11 Thread Ruben Garcia
Hi,

When I purchased Mreira months ago I was told by the Moroccan dealers
that it was a witnessed fall. Ok, lets be real, anyone can say
anything in order to make a sale. However, it looks as fresh as any
fall I've ever seen/found.

Photos here:
http://www.mrmeteorite.com/mreirameteorite.htm

Read the write up - it seems to agree that it is indeed a fall.

History: According to Ait Hiba Abdelhad, a fireball was seen in the
afternoon sky on December 16, 2012, several school children saw the
fireball explode and detonations were heard near the village of
Mehaires, Western Sahara. Pieces were recovered approximately 40 miles
south of Mehaires, near Mreïra, Mauritania, only a few days after the
event. The strewn field is in the area called Stailt Omgrain, which
is a local nomadic name. This is south of Mehaires and north of the
mountain Galbe lahmar. Therefore this is a possible fall associated
with the fireball of December 16, 2012.

This is getting repetitious!
I also use a Nikon, a big fat one, and natural daylight, in front of a 
south facing window. No flash, a slightly hazy day is best. And as 
little photo editing as possible.
I want my pictures to be true, not improved. It would be too easy to 
make a Tatahouine look greener than it really is.

Is there any scientific evidence related to its analysis to suggest that Mreira 
is not a fresh (observed) fall? If not, then I have to ask, if this fall had 
taken place in the US or France, would there have been any question?


I understand that the NWA situation is complex, but I believe that science, not 
opinion should drive the decision.

Look at the Indian Butte writeup. That is listed as a Fall with less evidence 
than Mreira in my opinion.

Read the write up - it seems to agree that it is indeed a fall.

History: According to Ait Hiba Abdelhad, a fireball was seen in the
afternoon sky on December 16, 2012, several school children saw the
fireball explode and detonations were heard near the village of
Mehaires, Western Sahara. Pieces were recovered approximately 40 miles
south of Mehaires, near Mreïra, Mauritania, only a few days after the
event. The strewn field is in the area called Stailt Omgrain, which
is a local nomadic name. This is south of Mehaires and north of the
mountain Galbe lahmar. Therefore this is a possible fall associated
with the fireball of December 16, 2012.

[meteorite-list] Mars Rover Opportunity Funding Ceases In 2015 Under NASA Budget Request

2014-03-11 Thread Ron Baalke


http://www.universetoday.com/110219/mars-rover-opportunity-funding-ceases-in-2015-under-nasa-budget-request/
 

Mars Rover Opportunity Funding Ceases In 2015 Under NASA Budget Request
by Elizabeth Howell 
Universe Today

NASA's preliminary (read: not finalized) budget for 2015 would eliminate 
funding for the long-running Opportunity rover mission that's discovered 
extensive evidence of past water on Mars in the past decade.

While the agency's baseline budget request shows no funding for the 
long-running 
Mars mission past 2015, NASA added that Opportunity is among several missions 
that could receive extension money if extra funds become available. Also, 
the budget needs to be approved by Congress before anything is set in 
stone.

Here's where Opportunity could get funding, under the current structure: 
The White House has proposed a $56 billion Opportunity, Growth and Security 
Initiative across the U.S. government that would surpass the budgetary 
spending limit that Congress set in December. (Some news reports indicate 
the Republicans are not on board with this, but it's early yet.)

NASA, meanwhile, is undertaking a regular review of several Mars programs 
(among others) to see which ones give the best return for funding. The 
missions to be reviewed include MSL [Mars Science Laboratory/Curiosity], 
MRO [Mars Reconnaissance Orbiter], Opportunity, Odyssey and Mars Express, 
NASA stated. But as the table below shows, right now Opportunity has no 
funding in fiscal 2015, while the other missions do. (Note that funding 
would cease for Odyssey in 2017 under this plan.)


[Table]
NASA's budget request for fiscal 2015 eliminates funding for the Mars 
Exploration Rover Opportunity in 2015. Click for a larger version. Credit: 
National Aeronautics and Space Administration FY 2015 President's Budget 
Request Summary

Here's what NASA's budget request says about the extended funding:

Planetary Science Extended Mission Funding: Provide an additional $35.0 
million to increase support for extended missions prioritized in the upcoming 
2014 Senior Review. The Budget provides funding for high priority extended 
missions such as Cassini and Curiosity. However, it does not provide funding 
to continue all missions that are likely to be highly rated in Senior 
Review. The funding augmentation would allow robust funding for all extended 
missions that are highly ranked by the 2014 Senior Review, enabling high 
science return at relatively low cost, instead of potentially terminating 
up to two missions or reducing science across many or all of them.

On Twitter, the Planetary Society's Casey Dreier, its director of advocacy, 
wrote a few tweets about the budget last night, including one addressing 
Opportunity. As expected, MER Opportunity has no funding as of Oct 1st, 
unless supplemental funding is added, he said, adding that a bright spot 
is that the Curiosity mission has funding through fiscal 2019 (which is 
as far as the numbers go in the budget request.)

Opportunity landed on Mars in January 2004 and has rolled more than 24 
miles (38 kilometers) in the years since, long outliving its twin Spirit 
(who ceased communications in 2010). Universe Today's Ken Kremer recently 
covered the contributions these rovers made to science in the past 10 
years.

The last Opportunity update on March 4 described how controllers deliberately 
crushed a rock under the rover's wheels as it explored Endeavor Crater, 
where Opportunity has been trundling along since 2011.

On an unrelated note, NASA announced today (March 11) that the Mars 
Reconnaissance 
Orbiter went into safe mode after an unscheduled swap from one main computer 
to another, but the spacecraft is expected to be working normally in 
a few days. (MRO has been through several safe mode incidents over the 
years, including several times in 2009.)

Hi Matt,

Well, it was not intended to be an Ad.  But, I do get your point!  I
wonder how a similar type of subtle advertising can be stopped if
indeed Art will start charging for ads in April.

Will all advertising be disguised as legitimate topics? And how would
anyone be able to tell the difference?

A few suggestions for topics on April 1, 2014.

This excerpt above is basically only the proof that it was a fall.
The lesson here is that NWA documentation needs to be meticulous with
identified individual eyewitnesses that corroborate with anything else
like cameras etc. (e.g. Chelyabinsk). What didn't measure up in this
case, was the anecdotal recovered fresh meteorites 40 miles from an
event that only anonymous school children witnessed. Also, no
documented strewn field was submitted (in situ photos etc.). I suppose
this can be a problem when people want to keep the actual strewn field
location a secret to keep out competing hunters?

No such thing as too much documentation.

Read the write up - it seems to agree that it is indeed a fall.

History: According to Ait Hiba Abdelhad, a fireball was seen in the
afternoon sky on December 16, 2012, several school children saw the
fireball explode and detonations were heard near the village of
Mehaires, Western Sahara. Pieces were recovered approximately 40
miles
south of Mehaires, near Mreïra, Mauritania, only a few days after
the
event. The strewn field is in the area called Stailt Omgrain,
which
is a local nomadic name. This is south of Mehaires and north of the
mountain Galbe lahmar. Therefore this is a possible fall
associated
with the fireball of December 16, 2012.

Hi Rob,

Nice to hear from you :-) I had clocked your page when researching
this and seen Ray Pickard's comments. I was also hoping to clear up
the classification as i have seen it as an L3.0 and a L3.2. I note the
classification is still pending?

All the best to you and yours :-)

 Ray Pickard, the Australian classifier of this stone, was very excited when
 he saw his thin section under the microscope.
 For my website (when I sold this material in 2009) he allowed me (without me
 asking him) to quote him:
 This meteorite is perhaps the most beautiful and interesting meteorite I've
 ever had the privilege of studying Ray Pickard.

 It's taking a lot of time to finish the classification though...

Hello Martin, Rob, and List,

Martin, congrats on your colorful thin section photos! Well, colour is
the problem I see myself faced with when looking at your thin section
pics. They look almost too colourful. Are you sure the section has the
proper thickness of 30µm (= 0.03 mm)?

Here are my numbers for your thin section pics so you and the other
list members know which pic I'm referring to:

1--2--3
4--5--6
7--8--9
10--11--12
13

Now, #1 does look like an RP chondrule at first sight but if it is a radial
pyroxene chondrule, the interference colours are too high. They should be first
order, i.e., gray or grayish-white. Either the TS doesn't have the proper
thickness or we are looking at something else: the high interference colors
would speak in favour of a deformed (?) BO chondrule with slender bars.

Chondrule #10: same problem! Provided the IF colours are correct, this
is another BO chondrule. If it is an RP chondrule, the interference colours
are wrong.


My NWA 5730 has lots of metal-rimmed chondrules, FeNi is troilite-rimmed,
porphyritic chondrules are abundant, numerous porphyritic chondrules harbor
light-green translucent hypersthene crystals + a gray clayey-looking broken
chondrule (d = 5.1 mm). I wonder if it is something carbonaceous or if it
experienced some kind of silicate darkening.

Best wishes from the owner of a 21.4 gr endcut that I got from Rob in 2011!

Re: [meteorite-list] Cornucopia of chondrules

2014-03-11 Thread rickmont

Martin, Bernd et al,
Wonderful photos, and I immediately wondered the same thing.  As a painter 
of faux (not reality) chondrules, I have steered away from pyroxene so far 
simply because I want to explore grays and black-and-white before tackling 
the radial chondrule. (The big picture includes larger works with types 
3-4-5, eventually into achondritic fantasy-land).  Bernd, you have shed 
some valuable light!  If I am concluding correctly:  thicker slices in TS 
can cross into higher order colors for pyroxene?  Ah!  This will be my 
excuse if I am confronted with a colorfully painted pyroxene element by the 
true meteoriticist!


I will strive to be true to the accepted dimension however.  So, 
meanwhile, Martin, can you share info on the depth of your slice-photos?


Sincerely,
Richard Rick Bob Montgomery

 Mojave Crater: Source of Martian Meteorites?

 Where did the Martian meteorites called shergottites come from? A team
 of European researchers believe their launch pad was a fresh-looking
 55-km-wide
 crater punched into ancient terrain about 3 million years ago.

 Imagine walking into a room full of geologists, plunking a box full of
 rocks on a table, and asking them to figure out where on Earth your samples

 came from.

 [Image]
 The Los Angeles meteorite, found in California's Mojave Desert, has proven
 to be a chunk of Mars known as a shergottite. The scale cube is 1 cm on
 a side.
 Copyright 2000 Ron Baalke.

 That's the challenge facing the researchers who study meteorites from
 the planet Mars. The count of Martian stones now totals about 150,
 representing
 69 discrete falls on Earth. They're all igneous rocks and fall into three
 compositional clans known as shergottites, nakhlites, and chassignites
 - named for an archetype within each group. (There's one oddball, an ancient

 rock known as ALH 84001, that has gotten a lot of attention in past years.)

 The rocks themselves are old. However, they were blasted from the Martian
 surface in the geologically recent past, based on how long they were exposed

 to cosmic rays in space before reaching Earth: 11 million years ago for
 the nakhlites and chassignites, and just 1 to 5 million years ago for
 the shergottites.

 So where'd they come from? That question has dogged planetary geologists
 for decades. But they've now got powerful new tools - three heavily
 instrumented
 orbiters around Mars - to try to identify the interplanetary launch pads.
 Several researchers have suggested young-looking Martian craters as
 possibilities
 in the past.

 [Image]
 Mojave crater, 36 miles (58 km) across, is a fresh-looking crater on the
 ancient Xanthe Terra plain of Mars.
 NASA / JPL / Arizona State Univ.

 Now a trio led by Stephanie Werner (University of Oslo) has put forth
 a candidate site as the source of the shergottites. As the researchers
 note in the March 6th online edition of Science, the crater is surrounded
 by a broad apron of dusty, ejected material that bears few impact craters;
 this, together with other evidence, suggests to them that Mojave formed
 within the past 5 million years. Also, spectra obtained with the European
 Space Agency's Mars Express orbiter shows patches within the crater enriched

 in the minerals pyroxene and olivine, which are common in shergottite
 meteorites.

 But the case for Mojave as the source crater isn't ironclad. For starters,
 it's a big impact - 34 miles (55 km) across. Werner and her team admit
 that craters of this size should occur on Mars only once every 35 to 50
 million years, so a geologically recent blast of that size is statistically

 unlikely.

 Moreover, the crater's rim and deposits have been crosscut by multiple
 sets of intersecting streambeds that end in broad fans of sediment - very
 reminiscent of landforms in the Mojave Desert of California and the
 Southwest.
 Geologists believe this sort of erosion occurred on Mars very early in
 its history - but not within the past 5 million years. Moreover, the craters

 flanks show several episodes of runoff; it apparently didn't happen all
 at once.

 Werner isn't concerned, though. It can be multiple stages even if it
 happened only five million years ago. It can be multiple stages even
 if it happened only five million years ago, she explains. Hydrothermal
 systems in such a crater can easily exist for a few hundred years, and
 also seasonal variations may produce several episodes.

 [Image]

 NASA / JPL / Univ. of Arizona

 Another issue is that Mojave punched into some of the oldest rocks on
 Mars, a region called Xanthe Terra that dates at least 4.1 billion years
 ago. Further, Mojave lies at the confluence of two giant flood channels,
 Simud Vallis and Tiu Vallis. But most researchers consider the source
 rock for the shergottite meteorites to have solidified between 150 and
 600 million years ago. Nakhlites and chassignites aren't dramatically
 older, probably 1.3 billion years. The consensus was (and still is) that
 the shergottites are young, comments Alfred McEwen (Arizona State
 University).

Carl I couldn't agree more with you and other people on here that
brought up a good point that NWS are still kept secret where they
have been found and documentation that backs up that its a fall.
I hope this is a lesson learned and in the future people in the region 
start to be more transparent with documentation on the fall. But again,
there have been falls in the USA were its be years before info is published,
but I guess what they have for them is video cameras and a lot more eyewitness.
I wonder if they set up sky cams in the NWA region how many more falls would be

Re: [meteorite-list] ADS - slick veiled offers and Donations for the List? (Question for Art)

2014-03-11 Thread Galactic Stone Ironworks
Hi Listees (and especially dealers and collector/dealers) :

Ruben raised a good point.  How will Art decide what is an
advertisement and what is not?  It is not difficult to raise a
discussion based around material that a certain dealer or dealers have
for sale.  Such posts are basically organic ads.  They are not
explicitly labeled as an advertisement, but they are a veiled offer
with the hopes that someone will click the link and buy something.
The example I give below is a strictly to illustrate my point.  The
piece in question is already sold.

For example, I could start a discussion about Darwin Glass like this :


Hi List,

Has anyone ever seen a piece of Darwin Glass with a natural hole in
it?  Or how about LDG or Moldavite for that matter?  I've seen a lot
of variations of impact glass, but have never seen one with a natural
hole in it.  How rare is this and what process is responsible?

Photo of the Holey Darwin Glass -
http://www.galactic-stone.com/product/darwin-glass-tasmanian-impact-glass-w-natural-hole

Best regards

--

Let's face it, there are slick and intelligent people on this List
(far smarter than I), and it's not difficult to squeeze an offer into
a discussion post.

Second point : we could have a fundraiser for the List and send the
proceeds to Art.  I would gladly participate in that and put up some
specimens for the cause.  Also, Art has a button on the Meteorite
Central home page for donations.  Does anyone actually click it and
donate?  Honestly, until Shawn Alan said something about it yesterday,
I had forgotten that the homepage even existed.  I get List emails to
my inbox and rarely visit the homepage.  I had not been there in years
and couldn't even remember what it looked like.

Question for Art - how much money would you need per month to offset
the costs of maintaining the List?  Maybe if we (Listees) knew what
the damage was (your costs), then we could work to help pay that.

I find the List to be a great resource for knowledge (torpid or
not), and would do my small part to help.  I post ads regularly, but I
do not make a lot of money from the List.  The vast majority of my
sales come from my personal email client list, Facebook, Twitter, and
organic visitors from the web (Google, etc).  This List ranks third or
fourth behind my email list and social media (FB, Twitter,
Pinterest) in terms of how many sales I make.  But, there are some
bigger dealers who have specimens priced at thousands or tens of
thousands of dollars and they make more money from this List in one
sale than I might make in an entire year.  IMO, those dealers should
pony up the most.

Best regards,

MikeG

PS - I have no problem with paying for ads.  I am just curious about
how this will work.  And why dealers who make tens of thousands of
dollars per year as a result of ads on this List will be paying the
same fee as smaller dealers who make a few hundred dollars per year
from these same ads.  There seems to be a disparity here.  I already
send buyers and business to some larger dealers who are friends of
mine and I gladly do it when potential buyers want large or special
specimens that I do not have and cannot get easily.  Am I now expected
to subsidize their ads as well?

 NWA 7989 - One of the nicest shock melt Eucrites to come out of the desert
 in a while.

 NWA  - a nice thumbprinted  3,370 gram unclassifed NWA. If nothing
 else

 cents per gram.
