You are correct that Geology departments have neither the
equipment nor the expertise to recognize and classify meteorites, in
general. This is very specialized and requires the skills (in some
respects, almost an art) and experience of researchers who also have
the necessary equipment. The 'expert' can interpret a
thin-section to determine the meteorite's petrologic type, but electron
(ion) microprobes are also necessary to analyze its chemical makeup, such
as its fayalite % (H, L, LL). Furthermore, one has to know how to use
said equipment and apply it to meteorites. ( It not like just taking up a
collection and buying a microprobe and reading a graph! )
The following is a description from the U.C.L.A. Geochemistry
website:
<<are operating a high resolution, high-sensitivity ion microprobe -
the first of its kind in the western hemisphere>>
<<Chondritic meteorites are studied with petrographic, chemical and
isotopic techniques ... Differentiated meteorites and lunar samples offer
valuable comparisons for igneous processes in systems simpler than those
occurring on Earth. Neutron activation is used to survey concentrations of trace
elements, for example, noble metals near geological boundaries associated with
inferred catastrophic impact events.>>

eBay M-Wrong
Ken , I think your making to big a deal out of this. Any serious person
will check them out before spending a sizable amount of money You spent 40.00
on a phony
but, look what it got you your now an expert on the whole
subject You know what they say about guilt or innocence in the criminal
justice system " Its better that
100 guilty men go free than 1 innocent
man be found guilty " here's how that applies to meteorites Its better
that a 100 people buy a 40.00 fake than 1 real
meteorite be
discarded Also even fake meteorites can make people curious and
genuinely interested which means your collection is worth more just by the
amount
of that interest I am a licensed landscape contractor and guess
what? I charge more because a lot of times the unlicensed can't do the
work therefor more work is
funneled to me more demand for a higher
standard means more for $ me. I think meteorites will naturally follow
that same course and be found out in the end only
to the benefit of
the legitimate collector I really think the focus should be on quicker
and more conclusive testing Universities are not well equiped for real
testing
and I know by thier methods they are probably overlooking the most
rarest type the low metals since they primarily test with a magnet Where
are all the private labs
hiding where you can pay and find out EXACTLY
what you have? , they are out there but' their not set up for meteorite ID
that well Its not an easy process getting
a straight answer on a
rock sample in fact its very difficult it needs to be streamlined Is
their a machine you can buy to test samples? shove it in like an oven turn a
dial out comes a print out of your samples enerts, if there is I'm
going to get one and start charging all those fakers 5$ each to conclusively
absolutely, undeniably
certifiably identify their ? I think ther
could be a big demand What do you think? Also check
this out, this is what the universitiy called quartz let me know what
you think
