Place of discovery:

Morocco (28.0025°N, 11.1316°W)

Date of Collection:



Martian meteorite (Shergottite)

Mineral compositions and Geochemistry:

Microprobe examination of a polished epoxy mount shows 60% pyroxene, 35% maskelynite, 2% ulvöspinel, 2% melt pockets with silica, minor merrillite, trace chlorapatite and pyrrhotite. Pyroxenes show core-to-rim zonation. Pyroxene grains 200 μm to >1 mm, maskelynite domains 50 μm to >1 mm. Two distinct pyroxene compositional trends.
