Writeup from MB 104:
Komin Yanga 11.69972°N, 0.13694°E Gourma, Burkina Faso Find, doubtful fall: 2014 Classification: Ordinary chondrite (H5) History: The sample was collected ~45 km southwest of Fada N’Gourma in 1984 and there are unconfirmed reports of it being a witnessed fall. It was brought by local villagers through an intermediary to geologist Demetrius Pohl in 2014. The single piece had a broken face and must have originally been about 20% larger. Petrography: The sample is brecciated; it contains centimeter-sized H-chondrite clasts and has a light/dark structure. There are centimeter-long metal veins and dark glassy shock veins. There are a few metal nodules up to 4 mm in maximum dimension. Also present are metal grains containing small irregular wormy grains of troilite and 1-15-μm-size grains of metallic Cu. Plagioclase grains are 6-10 μm in size. Also present are grains of Ca-pyroxene (Fs5.8±0.3 Wo46.0±0.3; n=4). Chondrules are readily delineated in thin section. | ||||||||||||||||||||||||||||||||||||||||
