Name: Wangdaodeite RRUFF ID: R150142 Ideal Chemistry: FeTiO3 Locality: Suizhou L6 chondrite, Dayanpo, 12.5 km southeast of the city of Suizhou, Hubei Province, China (35°18’N, 113°35’E) Source: Xiande Xie and Xiangping Gu Owner: RRUFF Description: Type sample. Aggregates of irregular black grains, ranging from 2 to 18 μm in diameter, composed of nano-sized crystals (10-80 nm), in shocked veins associated with xieite, ringwoodite, majorite, olivine, pyroxene, maskelynite, kamacite, troilite. Status: The identification of this mineral is confirmed by single-crystal X-ray diffraction and chemical analysis. |
