Nephrite has long history of mining and use, and occupies a very important position in jade culture in China. According to occurrence, the genetic types of dolomite-related nephrite can be divided into contact metasomatism type (skarn-type/ magmatic hydrothermal type), regional metamorphism and metamorphic hydrothermal type, in which contact metasomatism type is the most important and the main genetic type of high-quality nephrite. This paper mainly summarizes the geological characteristics, mineral composition, whole rock main and trace element contents, ore-forming fluid composition, zircon/ mica age, spatial distribution and metallogenic regularity of nephrite from 6 nephrite ore belts and mining areas in China. The main mineral composition of nephrite is tremolite. The whole rock Cr-Ni and FeO-Fe/ (Mg + Fe) element mapping are mainly located in the nephrite area related to dolomite marble. The age of the surrounding rock, zircon or mica in the nephrite can constrain the age of the formation of the nephrite ore belt. Based on this and regional geographical location, the nephrite ore belt in China can be divided into the Xinjiang in the West Kunlun ore belt (Shache-Yecheng, Hetian-Yutian, Qiemo-Ruoqiang ore belt, the upper limit of the formation age is 350-450 Ma); the Qinghai Golmud in the East Kunlun ore belt (Da (Xiao) zaohuo; Sanchakou; Tuolahaigou, the formation age is 240-300 Ma); the Northeast region (Xiuyan, Liaoning (Hemo nephrite about 150~250 Ma, old nephrite about 1700 Ma); Panshi, Jilin; Tieli, Heilongjiang); Southwest China (Luodian, Guizhou; Shimian and Longxi, Sichuan), Central South Region (Luanchuan, Henan (volcanic rocks about 682 ± 62 Ma); Linwu, Hunan; Dahua, Guangxi (diabase about 260 Ma)); East China Region (Liyang, Jiangsu; Nanping, Fujian). The ore-forming fluid composition of contact metasomatism type nephrite deposit is mainly magmatic water, meteoric water and CO2 derived from decarbonation of the dolomite marble in different proportions (such as Hetian, Xinjiang). The ore-forming materials of Mg and Ca come from dolomite marble, while Si and H2O come from magmatic hydrothermal fluids. The formation of nephrite mainly experienced contact metamorphism, prograde metasomatism and retrograde metasomatism stage. The metasomatism process is diopside skarn → tremolite skarn (coarse-grained), epidote skarn→tremolite skarn and coarse-grained tremolite → fined-grained tremolite. The mineralization process of regional metamorphism nephrite deposit is closely related to regional metamorphism rather than magmatic activity., and the ore-forming fluid is mainly meteoric water (such as Chunchuan, South Korea). Metamorphic hydrothermal type nephrite taking old nephrite in Xiuyan, Liaoning as an example, the ore-forming fluid is mainly metamorphic water The ore-forming materials Mg and Ca come from marble, and Si and H2O may come from the siliceous hydrothermal solution formed by regional metamorphism and mixed magmatism. Nephrite is mainly produced in the areas with strong tectonic activity, and in the areas with strong contact alteration zone between intrusive rocks and carbonate rocks. Mineralization marks, tectonic marker, wall rock alteration marks, secondary deposit marks, ancient mines marks. etc .
