天山北山成矿带铜矿控矿因素及找矿远景分析

斑岩型铜矿、铜镍硫化物铜矿、沉积型铜矿和海相火山型铜矿石天山北山地区重要的通矿床类型。该区构造演化非常的复杂,前寒武纪基底演化与早古生代大陆裂解以及古生代洋壳演化以及晚古生代板块等构造演化阶段和铜矿成矿有着密切联系。地层对铜矿的成矿主要影响是作为矿源层与特定沉积建造;大地构造环境和区域性的大断裂和韧性剪切带以及火山机构等是重要的控矿构造。另外该区强烈的岩浆活动对铜多金属矿的形成非常密切。

Analysis of ore controlling factors and prospecting prospect of copper deposits in Beishan metallogenic belt,Tianshan

Porphyry copper deposit,copper nickel sulfide copper deposit,sedimentary copper deposit and marine volcanic copper deposit are important types of Tongshan deposit.The tectonic evolution of this area is very complex.The basement evolution of Precambrian is closely related to the early Paleozoic continental breakup,the Paleozoic oceanic crust evolution and the late Paleozoic plate tectonic evolution stage and copper mineralization.The main influence of strata on the mineralization of copper deposits is as the source bed and specific sedimentary formation;the geotectonic environment,regional major faults,ductile shear zones and volcanic mechanisms are important ore controlling structures.In addition,the strong magmatic activity in this area is very close to the formation of copper polymetallic ore.
