摘　　要：播卡金矿床位于滇中元古界铜金多金属成矿带之东川矿集区。重点报导了区内与成矿密切相关的岩浆岩的岩相学的观察资料与测试结果,研究表明,这套火山岩为细碧—角斑岩组合。随着播卡地区细碧—角斑岩中金矿的发现,它不仅证明区内铜金成矿作用与海相火山岩的岩浆作用有着密切关系,同时也暗示该区存在寻找块状硫化物铜金矿的潜力。The Boka gold deposit is located in Dongchuan ore concentration area, and belongs to Yunnan Proterozoic copper polymetallic mineralization belt. This paper reports the petrography of volcanic rock that is closely related to mineralization. Our studies show that the volcanic rock is spilite-keratophyre assemblage. With the exploration of gold deposit which occurs in spilite - keratophyre assemblage, it not only proves that copper-gold mineralization has a close relationship with marine volcanic magmatism, but also infers that this area should be considered as a potential prospecting target for massive sulfide copper and gold deposit.
