有机质在滇中郝家河砂岩铜矿成矿过程中的作用

The Role Played by Organic Materials in Formation of the Haojiahe Sondstone Type Cu-deposit in Central Yunnan

郝家河砂岩型铜矿产于滇中中生代陆相红色碎屑岩建造中是滇中砂岩铜矿的一个中型铜矿床.本文以矿区宏观地质特征和微观分析数据为基础,论述了有机质参与成矿过程的事实及其在成矿过程中的作用.

Among the sandstene type copper deposits in central Yunnan, the Haojiahe Cu deposit is medium in size and occurs in a Mesozcic ccntinental red clastic rock formation. On the basis of the study on macroscopic geological charactcristics and microscopic data analysis, it is demonstrated that organic materials had really participated in the mctallogenic process of the deposit and played an important role.
