摘要
蛤蟆石金矿床的控矿构造是北北东走向的走滑型韧性剪切带，成矿物质主要来源于双桥山群；韧性剪切带的变形变质作用是主要的成矿作用。矿床成因属于韧性剪切带控制的中低温变质热液（叠加岩浆热液）石英脉型金矿床。
The NNE-trending strike-slip ductile shear zone is the ore-controlling structure of the Hamoshi gold deposit, the source bed for mineralization is the Shuangqiaoshan Group. while deformation and metamorphism that took place in the ductile shear zone facilitated the ore-forming process. ln genesis, this deposit is a mesothermal-epithermal quartz-vein type gold deposit controlled by ductile shear zone. The hydrothermal solution that formd the deposit is mainly of metamorphic origin but subsequently this deposit was overprinted also by hydrothermal solution of magmatic origin.
