(Northwest Africa)

Purchased: 2021 Aug

Classification: Ordinary chondrite (H4/5)

Petrography: (K. Metzler, IfP) Ordinary chondrite with some porosity, showing well-defined chondrules and chondrule fragments. Secondary feldspar grains <50 µm. High amounts of Fe-Ni metal, mostly oxidized by terrestrial weathering.

Geochemistry: Mineral compositions and geochemistry: The mean olivine composition is Fa18.4±0.2 (Fa18.1-18.6; n=12) and the mean low-Ca pyroxene composition is Fs16.1±0.3Wo1.6±0.2 (Fs15.6-16.8Wo1.2-2.0; n=12).

Classification: H chondrite based on mineral chemistry. Petrologic type 4/5 due to the well defined chondrules, but equilibrated state of olivine and low-Ca pyroxene.

Specimens: Weight of individual stones (g): 1884; 1587; 1268; 1218; 1213; 1100; 715.
