The former consists of tiny olivine and low-Ca pyroxene grains with interstitial glass. Accessories are Fe-Ni metal and troilite, both of which are heavily terrestrially altered.
Geochemistry: Mineral compositions and geochemistry: Mean composition of chondritic relicts: olivine Fa25.4±0.7 (Fa25.1-25.7; n=11); Low-Ca pyroxene Fs21.4±0.4Wo2.1±1.1 (Fs20.9-22.5Wo1.2-4.8; n=12).
Classification: L-melt rock, based on texture and mineral chemistry of chondritic relicts.
