There is a difference between what we should do and what we are able do.
If I had 50 supposed martian meteorites up to 8 gram I would like to
have a scientist look them over so nothing is lost for science. In this
case I think there shouldn't be any problem to find a lab that wanted to
take a look. Let the lab verify that all stones are martian or at least
most probably martian if they match them visually and only test a few
stones.
If I had (which I do) 50 meteorites under 8 grams that looks like
ordinary NWA weathered stones then I don't think I could find any lab
that wanted to classify them even if I donated the whole lot.
In a perfect world every meteorite should be classified, measured,
positioned and registered but we can only do a limited amount of work
and that should be done where we (science) get the most value. To
classify more Mali, NWA 869 or Camel Donga is probably just a waste of
money.
Best of all is if dealers and collectors keep an eye out for strange
stones among the ordinary ones. I don't remember exactly but I think
someone had a scientist going over hundreds of kilos of NWA 869 to
cherry-pick some interesting stones. Haven't heard any result though.
Of course, the rules are only suggestions and no one is enforcing them.
Some dealers classify their martian meteorites and some is selling them
unclassified but still calls them martian.

Doug,
This is what I'm thinking.
Lets say I bought 50 Mars stones and the biggest was only 8 grams, now
what?
I'm thinking what do I do now Doug?
Mike Farmer brings up a good point tens of thousands of Gao stones,
and why
dont cut them or classify all of them! Same with Canyon Diablo.

Tim,
I give up, what are you thinking - to sell them unclassified except
for a 2
gram stone and then give a scientist 0.4 grams in exchange for
classifying
the entire fall? Naughty naughty

What if you had 20 stones all around 2 to10 grams each all from the same
fall?

Andi,
What about a stone that is 5 grams?

Hi Pete
20% or 20g is the rule

Betreff: [meteorite-list] Samples
Hello Listies,
Maybe someone can answer this for me.
Where did the 20% value come from to classify a meteorite? If a meteorite
were found
that, say , was 1.2 grams, unpaired with anything else, then the
sample must
needs be
.24 grams, if I've figured right. This is a very significant portion
of the
meteorite.
Then on the other hand should one be found that was 1 ton, the sample
would
be 400
pounds. If a classification can be done with .24 gram, why can't it be
done
with a much
smaller piece of the 1 ton meteorite?
Just learning here, please bear with me.
Thanks,
Pete
