Modern techniques such as microscope, electron microprobe analysis, chemical analysis, and isotope analysis were employed. The results show that the nephrite from Sangpiyu is mainly composed of tremolite (> 94%), with minor apatite, chlorite, epidote, serpentine, calcite and limonite. Tremolite texture is characterized by microcrystalline-cryptocrystalline aggregates. It is concluded that the nephrite deposit in Sangpiyu Village is a kind of metamorphic hydrothermal deposit.
