招远市夏甸金矿含金流体成因及就位机制的研究

Origin of Gold-bearing Fluid and Study on Its Emplacement Mechanism of Xiadian Gold Deposit in Zhaoyuan City

摘要:

通过对夏甸金矿石英中流体包裹体成分和矿石微量元素测定 ,得出含金流体为幔源—岩浆和变质复合成因。依据容矿断裂形成机制的理论分析、高温高压实验研究、含金流体就位过程及容矿断裂形成环境的探讨 ,提出复合含金流体主动就位机制。

Abstract:

Through determination of components quartz fluid inclusions and microelements of ores in Xiadian gold deposit, it is regarded that the origin of gold-bearing fluid formed by mantle derived magma and metamorphism. According to theoretical analysis of ore-bearing fault forming mechanism, high temperature and pressure experiment, and emplacement process of gold-bearing fluid and study on ore-bearing fault forming environment, forcible emplacememt of composit gold-bearing fluid is put forward in this paper.
