Important Update News
The RRUFF Project (rruff.info) is being updated to improve its interface and content. The beta version of the update is accessible to the public at RRUFF.net. New data is only being added to the beta site. Please note that it is in development, and some components are not functional.
We are grateful to NASA for the funding of this effort.

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. |
