Plateau du Tademait 012 28.81794N, 0.92253E Adrar, Algeria Find: 2024 Feb Classification: Ordinary chondrite (H5) History: Reportedly this material was found in February 2024 in Algeria, and later acquired by Mohamed Ali Loud in Nouadhibou, Mauritania. Petrography: (K. Metzler, IfP Equilibrated ordinary chondrite with clearly visible chondrules and chondrule fragments. Secondary feldspar grains are mostly µm. High amounts of Fe-Ni metal, slightly oxidized by terrestrial weathering. Geochemistry: Mineral compositions and geochemistry: Mean olivine composition: Fa18.5±0.2 (Fa18.1-19.0; n=11); mean low-Ca pyroxene composition: Fs16.1±0.3Wo1.1±0.1 (Fs15.6-16.6Wo0.9-1.3; n=11). Classification: H chondrite based on mineral chemistry. Petrologic type 5 due to the equilibrated state of olivine and pyroxene and grain size of secondary plagioclase. Shock stage: C-S2 Weathering grade: W1 Classifier: K. Metzler, IfP. ADDITIONAL INFORMACIÓN: Some pieces showing a crust of iron hydroxides that has “captured” and cemented the contacting quartz grains. This lot comes with certificate of authenticity.
