摘要
新疆北部地质构造复杂，古生代火山活动很强烈。从寒武纪到二叠纪都有火山喷发，以泥盆、石炭纪火山喷发活动最强。铜铅锌矿的成矿与火山活动关系最密切。铜铅锌矿主要产于火山活动强烈，火山岩发育地段。依据铜铅锌矿成矿特征与火山活动的关系，新疆北部具有火山喷发—沉积、火山热液。
Northern Xinjjiang is characterized by complicated geologic structure and intense volcanic activities of Palaeozoic. Volcanic eruptive activities occurred from Cambrian to Permian,most intensely in Devonian and Carboniferous. Minerogenesis of copper,lead and zinc in the northern Xinjiang has a close relation with volcanic activities. Copper,lead and zinc deposits are mainly concentrated in the places where the volcanic activities were most intense and volcanics widely developed. According to the minerogenic character of copper,lead and zinc deposits and their relationship with volcanic activities,the northern Xinjiang has copper,lead and zincdeposits of volcano-eruptive-sedimentary,volcanic hydrothermal,and Subvolcanic types.
