lol the tkw game gets even more confusing. Jim's slice came off oy *MY*
piece and my piece was the smaller of two pieces that made up the 7.5kg
stone mentioned in 2656. so if the TKW for 2656 is considered to be the 300
or so gram orignal stone then everything is jake - if it's not then my piece
- ie 2871 was actually counted twice under two seperate nwa numbers...

>>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
