摘要
我国东部含金矽卡岩矿床占我国金矿床的35%左右,对其矿床成矿流体特征的研究可以提高金矿开采效率,对此详细探究了我国东部含金矽卡岩矿床成矿流体的规律特征。首先探究东部含金矽卡岩矿床岩相学特征,并对其三类包裹体进行分别探究;其次探究了含金矽卡岩矿床物理特征,包括其温度、盐度和密度等参数,最后分析了矿床流体包裹体的气相成分特征了解其成矿时期的内部构造。
The gold-bearing skarn deposits in the eastern part of China account for about 35% of the gold deposits in China,and the study of their ore-forming fluid characteristics can improve the efficiency of gold mining. Firstly, the lithofacies characteristics of the gold-bearing skarn deposits in eastern China were studied, and the three types of inclusions were explored respectively. Secondly, the physical characteristics of the gold-bearing skarn deposits, including their temperature,salinity and density, were studied. Finally, the gas phase composition characteristics of the fluid inclusions were analyzed to understand the internal structure of the ore-forming period.
