[meteorite-list] Adam's NWA 2989 Acapulcoite

[Matt Morgan]

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.
