Physical characteristics: Weathered brown exterior. A saw cut reveals a mosaic of very fine-grained polygonal crystals, also scattered metal/sulfide grains. Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows pyroxene, olivine, and plagioclase grains with apparent mean diameter 200±100 μm (n=40). Numerous grain boundary triple junctions throughout, abundant metal/oxide sulfide veinlets in grain boundaries and crosscutting silicate crystals. Apatite detected. Geochemistry: (C. Agee and N. Muttik, UNM) Olivine Fa10.6±0.2, Fe/Mn=22±1, n=5; low-Ca pyroxene Fs11.9±0.1Wo2.3±0.2, Fe/Mn=15±0, n=3; diopside Fs4.9±0.2Wo44.2±1.0, Fe/Mn=11±0, Cr2O3=1.18±0.13 (wt%), n=3, plagioclase Ab77.5±1.5An20.3±1.7Or2.2±0.2, n=2. Classification: Acapulcoite, not lodranite, based on presence of plagioclase, and grain size typical for an acapulcoite.
