摘　　要：阿尔金采石沟金-铜多金属矿是受火山机构控制的火山—次火山岩型矿床,产于火山—次火山岩岩体周边环状、放射状断裂构造中,矿体形态以脉状为主。地表及浅部以金矿化为主,而深部则以含金的铜多金属矿床为主,具有大型金及铜多金属的找矿潜力。文章就采石沟金矿地质特征及成因作初步探讨。<Abstrcat>Caishigou gold copper polymetallic deposit is a volcanic mechanism controlled volcano-subvolcanic rock type depositThere is gold mineralization on the surface and sallow part while gold containing copper polymetallic ore mainly occurs in deep part, showing potential for large scale gold and copper polymetallic ore prospecting
