斑岩铜矿研究中若干问题探讨

An approach to some problems of porphyry copper deposits

文章从全球角度对斑岩铜矿的若干问题进行了评述,对斑岩铜矿的源区及岩浆岩特征、Mash带的地质意义、埃达克岩与斑岩铜矿的关系、过渡岩浆的地质意义、中国斑岩铜矿概况及斑岩铜矿的一般模式等问题进行了探讨。

Porphyry copper deposits make up one of important types of copper deposits in the world. According to incomplete statistics, Cu resources from porphyry copper deposits account for 44.04 % of the total Cu resources of China. Therefore, strengthening the prospecting and exploration of porphyry copper deposits is of great significance in .solving the problem of Cu shortage in China. This paper comments on the situation of porphyry copper deposits in the world, dealing with such problems as source regions and host rock features of porphyry copper deposits, geological significance of the mash zone, relation of adakite to porphyry copper deposits, geological significance of transitional magma, and the general genetic model for porphyry copper deposits. A summarization is also given to porphyry copper deposits in China.
