摘　　要：小柳沟钨矿床属火山沉积—热液叠加改造型钨多金属矿床.W的成矿主要与矽卡岩中的Ca质有关,其成矿物质主要来源于围岩;Cu,Bi物质来源于围岩和岩浆热液,主要以硫化物的形式迁移和富集;Mo的物质来源主要为岩浆来源,也以硫化物的形式迁移和富集.矿床元素组分多样、元素组合复杂,矿床成因具"多期、多源、再造、复合"之特点.Xiaoliugou tungsten polymetallic ores are deposit and reconversion out of volcanic and hydrothermal rocks.The mineralization of W is due to Ca quality in the skarn,and stems from enclosing rock.Cu, Bi material stems from enclosing rock and hot magma liquids.It moves in the form of sulphide and is rich in collections.The material of Mo,from magma,moves in the form of sulphide and with rich collections too.Because various components in the mineral deposit,the composition of elements are complicated.The formation is found to be of many characteristics as following:different periods of time,multisources,reformation and compound composition.
