摘　　要：中国是世界上锑资源和生产大国。锑矿床划分为喷流沉积改造型、沉积改造型、变质再造型、岩浆热液型、火山热液型和外生堆积型六大类，细分十三亚类。近千个锑矿床（点）主要分布于华南锑矿成矿带、昆仓—秦岭锑成矿带、藏滇锑成矿带和阴山—天山锑成矿带。其中华南锑矿成矿带是最重要的锑成矿带，该带中有三个矿化集中区呈等间距分布。中国锑矿床最重要的成矿期为泥盆纪和侏罗－白垩纪。主要赋矿岩系为泥盆纪细碎屑岩—碳酸盐岩系，其次为元古界浅变质碎屑岩。China is one of the most important country of antimony resources and production. The antimony deposits in China can be divided into six types and in more detail into thirteen subtypes,the six types include that of exhalative-sedimentary-remoulded deposit,sedimentay-remoulded deposit,magmatic hydrothermal deposit,volcanic hydrothermal deposit,metamorphic-regenerated deposit and exogenic accumulation deposit.Around 1000 antimony deposits (ore points) or mineralized points mainly distrbute in South China Metallogenic Belt,Kunlun-Qinling Metallogenic Belt,Tibet-Yunnan Metallogenic Belt and Yinshan-Tianshan Metallogenic Belt of Antimony.Among them,South China Metallogenic Belt of Antimony is the most important belt of antimony,in which three centralized districts of antimony mineralization are distrbuted in equal intervals.The most important metallogenic period of antimony in China is Devonian and Yanshan Period.The principal host strata are fine clastic-carbonate rocks of Devonian,secondly light-metamorphosed clastic rocks of Proterozoic Group.
