摘　　要：银硐子银铅多金属矿床的矿体特征、矿石结构构造、稳定同位素特征显示矿床不是热水喷流沉积作用形成的,而是与岩浆活动有关的热液矿床。其成矿物质来源于基底地层而非赋矿地层本身,硫源来自深部岩浆源和热液途经地层,成矿介质水来自深部变质(分泌)水、地壳深熔、重熔岩浆水与大气降水等组成的复合水。成矿时代为印支期。The orebody characteristics,ore structure and characteristics of stable isotopesof Yindongzi Silver-Lead polymetallic deposit suggest that the deposit is not a hot water jet formed by sedimentation,but hydrothermal deposit related to the magmatic activity.Its minerals came from the basement strata,sulfur source came from deep magma source and hydrothermal via formation,ore-forming medium water was mixed water coming from deep metamorphism water,molten water coming from deep crust melting and atmospheric precipitation,etc.The metallogenic period was the Indosinian period.
