摘　　要：文章将中国11个产地的软玉(透闪石玉)矿床分为岩浆热液型和变质热液型两大类。其中岩浆热液型又根据侵入体的性质分为中酸性岩型、基性岩型、超基性岩型;变质热液型根据母岩特点分为碳酸盐岩型和蛇纹岩型;并从围岩和侵入岩体特征、矿体产状及大地构造背景等方面,对比分析了软玉矿床的相似性和差异性;总结了各产地软玉的品种、矿物成分、结构构造等矿物学特征;简单分析了软玉的找矿远景。In this study, nephrite （tremolite jade） deposits from eleven different producing areas in China are classified into magmatic hydrothermal and metamorphic hydrothermal deposit types. According to their main ore-forming hydrothermal sources, the magmatic hydrothermal type is further divided into intermediate- acidic, basic and ultrabasic rock types based on their intrusion properties. The metamorphic hydrothermal type deposits are classified into carbonatite and serpentinite types based on their parent rocks. Similarity and difference of nephrite deposits including characteristics of intrusion and parent rocks, ore occurrence and geotectonic setting is analyzed by comparative study. The paper has summarized nephrites varieties and their mineralogical features including mineral constitution and texture, and briefly analyzed the ore exploration potential.
