Natural occurrence and synthesis of two new postspinel polymorphs of chromite

A high-pressure polymorph of chromite, the first natural sample with the calcium ferrite structure, has been discovered in the shock veins of the Suizhou meteorite. Synchrotron x-ray diffraction analyses reveal an orthorhombic CaFe(2)O(4)-type (CF) structure. The unit-cell parameters are a = 8.954(7...
