Abstract: Hetian, Xinjiang, is a famous nephrite locality in the world. Recently, two nephrite localities are found in Liyang, Jiangsu Province, and Xiuyan, Liaoning Province. By using microprobe, XRD, infrared spectrum and SEM, the mineral composition, textures and structures, genesis and geological features of nephrites from the three localities are studied. The results show that they are composed mainly of tremolite with similar texture and structure
