Study of mineral inclusions in chromitites is of great significance in recognizing the origin of chromitites. In this paper, a large number of mineral inclusions including CPXs, OPXs, olivines, aspidolites, Na-Cr pargasites, CPX exsolution lamellaes were discovered in Sartohay high-Al chromitites, which were trapped in Cr-spinels as single phase and multiple phase when the Cr-spinels crystallized. Hydrous minerals, aspidolites and Na-Cr pargasites, imply hydrous condition, which probably indicates that parental magmas of chromitites were hydrous in back arc spreading ridge influenced by subducted fluid/melt. Taking account into the UHP diamonds discovered in chromitites, the formation of Sartohay chromitites probably experienced the deep mantle and shallow oceanic lithosphere setting.
