Thanks for posting Jim. This is sweet material folks and is probably the
best aca to come out of NWA, that I have seen. To plug 2871, I have a
few small pieces left under 10g for ~40/g. Thinly sliced and clearly
show the olivine and plagioclase crystals.

I got this slice in a trade from Blaine Reed under the NWA 2871 number

about the bad photos:

Subject: Re: [meteorite-list] Adam's NWA 2989 Acapulcoite
Hello list,
To get back to the spirit of Bernd's e-mail.
This NWA acapulcoite, a.k.a., NWA 2656, NWA 2714 and NWA 2989
(others?) is one of the better deals on the market right now. (And
Blaine Reed I think has the best price). The meteorite is somewhat
weathered and slices very in weathering, the darker....due to the
high amount of metal, the more weathered portions. My slice, sold to
me as NWA 2656, looks like Adam's NWA 2656...which is on the lower
end of this meteorite's weathering...from the slices I have seen at
least.
In case you thinking, I know acapucolites are achondrites....but just
what are these tourist city sounding meteorites really?
Acapucolites are igneous rocks composed primarily of olivine,
bronzite, and plagioclase and with nickel-iron as principal
minerals. They also have accessory minerals of clinopyroxene,
troilite, and schreibersite (among others).
I bought a thin section of the acapulcoite NWA 1054 (paired?) in
Tucson and was surprized at how small the mineral crystals are in
acapulcoites when I got it under the scope at home. The matrix
appears much finer then other achondrite's in my collection and
predictably, the olivine and plagioclase light up nicely in crossed
polars. I haven't figured out how to take thin section photos with
my new camera but I will work on it and share some with the list if
interested.
Anyway, this meteorite classification type has been selling in the
$200-$300 range until recently. If you don't have a piece....keep
your eye open. Or give Adam or John and e-mail...or possibly Blaine
a call.
Clear Skies,
Mark Bostick
