中国钨矿床成矿特征探讨

On the Metallogenic Characteristics of China's Tungsten Deposits

中国是世界上最重要的钨矿产区,矿床类型众多,对其成矿特征国内外许多学者进行了大量的研究工作。笔者总结了中国钨矿床的时空分布、成矿时代及钨在地壳中的迁移和富集方式;根据地层、岩浆热液、花岗岩演化、构造与钨成矿作用的关系,探讨了钨矿床的成因,特别是通过围岩与钨矿床关系的研究,认识到围岩岩性是决定钨矿物、控制矿床类型和矿体形态的主要因素。

China is the world% most important tungsten-deposit concentrated region with a large number of deposit types. Many scholars have done a lot of researches on the metallogenic characteristics of deposit types. This paper summarizes the spatial and temporal distribution of tungsten deposits, metallogenic epoch and the mode of migration and enrichment of tungsten in the earth＇s curst. The genesis of the tungsten deposits is discussed based on the relationship of tungsten formation to stratum, magmatic hydrothermal, granite evolution and structure. The lithological character of wall rock is the key factor determining tungsten minerals, deposit types and ore body morphometry out of the connection of wall rock with tungsten deposit.
