摘要
银定坂银多金属矿体赋存于旺墘大断裂内的二叠统栖霞组地层及地层与前坪岩体接触带中,矿体主要为地层、断裂及岩体控制,为燕山早期的前坪岩体中的成矿热液沿断裂运移至栖霞组碳酸岩地层发生接触交代型形成的矽卡岩型矿床。
The Yindingban silver polymetallic ore body is located in the Permian Qixia Formation strata and the contact zone between the strata and the Qianping rock mass within the Wangqian Fault.The ore body is mainly controlled by the strata,faults,and rock mass,and is a skarn type deposit formed by the contact metasomatism of the ore-forming hydrothermal fluid in the Qianping rock mass during the early Yanshan period,which moved along the fault to the carbon acid rock strata of the Qixia Formation.
