贵州八蒙锑矿地质特征及成因浅析

Geological characteristics and genesis of Bameng antimony deposit in Guizhou Province

通过对八蒙锑矿区域地质、矿体特征、矿石特征、成矿期次、成矿物理化学条件、控矿因素等分析,八蒙锑矿的硫、锑来源于地幔,成矿介质水主要来源于大气降水,成矿温度132℃~150℃等因素,认为区内锑矿成因属浅成低温热液型矿床,更进一步划分为浅变质岩层中热液充填交代石英脉型锑矿床。

Based on the analysis of regional geology,ore body characteristics,ore characteristics,ore-forming periods,ore-forming physical and chemical conditions,ore-controlling factors,etc.,the sulfur and antimony in Bameng antimony deposit come from mantle,the water in ore-forming medium mainly comes from meteoric water,and the metallogenic temperature is 132℃~150℃.It is considered that the genesis of the antimony deposit in the area belongs to epithermal hydrothermal deposit,which is further divided into shallow metamorphism The quartz vein type antimony deposit is replaced by hydrothermal filling in the metamorphic rocks.
