Hi Matt and list. I'm not an expert on the topic, but I think that part
of the problem may also be that meteorites such as those belonging to
the HED group are quite heterogeneous. If one sample contains a slightly
higher diogenite component it may come back as a howardite while a
sample with a lower diogenite component may come back as a eucrite. I
would imagine that two samples from the same stone could conceivably
come back with a different classification. If anyone can comment on this
and correct me if I'm wrong I would appreciate it!
Cheers

Just to add a note...
There is a fundamental scientific problem of classifying meteorites.
Try sending two pieces of the same meteorite to different labs. Chances
are you will get different results.
For instance, I have "L5's" that came back as "L4's" and "L6's".
"Regolith" this and "Primitive" that.
I heard the same situation happening for NWA 1929, either howardite OR
eucrite. I understand some of it is "interpretive".
The system itself is flawed.
Ideally, we need an NWA consortium of labs to correct this and have type
specimens on hand.
This SEEMS to be an easy fix, but university politics plays a huge role.
So all you scientists who study NWA's, how about a network for meteorite
"data sharing"? It will make ALL our lives easier...

While I truly believe this practice is ultimately costly to the
collector,
truer words have never been spoken. Thanks Mike:
"Virtually every dealer including myself has been or is guilty of this,
we are in the process of correcting the situation and to start people
MUST immediately comply or this will just spiral downward as we see
tonight."
So, for now, we make it right. We follow the rules and pay out to prove
pairings. We wait longer to get to market and costs go up because repeat
lab
fees and repeat type specimens factor into prices per gram. I don't like
it
one bit but that's what we do. I will be finishing off my "likely
paired"
howardite as such but new specimens are already off to the lab,
specimens I
know are paired.
While I seriously doubt the law has any holding here, the NomCom asks
this
of us. Bottom line, if two folks buy bread from the same baker...they're
eating the same bread. The full weight of this ruling will soon be felt
by
all as we bog down institutions who want to study meteorites with
incessant
pairings, not much grant money in pairings, not much recognition. But
this
is what we do...for now.

Subject: [meteorite-list] Meteorite numbers
To clarify something that is obviously causing some problems in the
meteorite world right now, I want everyone to know that
NWA 788, 787, and NWA 482 are numbers that came from rather large or
meteorites with hundreds of pieces bought during one of my
expeditions.
The Hupes and many other people have the right to those numbers.
Now, there are other numbers being widely used without proper title
(as Dr
Grossman has stated publicly and with finality that people do not own
numbers, but numbers are assigned to specific meteorite specimens and
must
not be used with other meteorites just because you heard or someone
told
you it is the same).
Let's all please stop this practice as it is really hurting our
business
and hobby. Virtually every dealer including myself has been or is
guilty
of this, we are in the process of correcting the situation and to
start
people MUST immediately comply or this will just spiral downward as we
see
tonight.
I perused eBay today and it is still rampant with sellers using
numbers
they seem to have drawn from a hat. So please ask you seller next time
you
buy something, how they got that number, who it was assigned to and if
not
them, just how they came to call it that.
