Thin Section (,2) Description: Tim McCoy
The section exhibits a granoblastic texture with abundant triple junctions and grain sizes of 100-300 microns. Olivine, pyroxene, plagioclase and coarse metal are uniformly distributed, but sulfide is markedly depleted relative to chondrites. Olivine is Fa11, pyroxene is Fs11Wo2 and plagioclase is An15Or5. The meteorite is a member of the acapulcoite-lodranite clan. It is not paired with MAC 88177, but is similar in some respects to the transitional members EET 84302 and GRA 95209.
