摘要: 在已有中国锡矿床科研成果的基础上,对中国102个中型及以上规模锡矿床进行了系统地归纳与总结。在成矿地质条件的基础上,按成矿作用的特点,再根据主要矿物的组合和蚀变特征,可将中国主要锡矿床分为热液型、夕卡岩型、变花岗岩型、云英岩型、斑岩型、伟晶岩型和砂矿型7种类型,其中热液型、夕卡岩型和砂矿型为主要矿床类型。锡矿床的主要成矿时期为燕山期,主要赋矿岩系为三叠纪的灰岩、大理岩系。结合主要矿床的品位模型,可以发现产于燕山期花岗岩中的热液型锡矿床和夕卡岩型锡矿床是今后主要的找矿类型及方向。

Abstract: This paper, based on the research advances of China's Tin deposits, summarizes 102 middlesized and above deposits by their geology, mineralization, and major minerals combination and alteration. China's Tin deposits can be classified into hydrothermal, skarn, metagranite, greisen, porphyry, pegmatite and placer types, of which hydrothermal, skarn and placer are the major. The main mineralization period is Yanshanian era, hosting rock is the Triassic limestone and marble, which, combined with the grade model, indicate the future exploration in hydrothermal and skarn types in Yanshanian granites.

Key words: tin deposit, deposit category, mineralization period, grade model, China
