天山—北山成矿带铜矿控矿因素及找矿远景

Ore controlling factors and prospecting prospects of copper deposits in Tianshan Beishan metallogenic belt

天山、北山成矿带铜矿类型主要包括侵入岩、海相火山、沉积岩等,该地区铜矿的形成演化阶段包括前寒武纪、晚古生代、早古生代以及中新生代。矿源层和特定成矿构建能够促使地层迅速成矿,控矿主要表现形式为该区域构造环境,火山岩、区域断裂、成矿作用以及侵入岩因素和铜矿存在密切联系,所以,该成矿带具备良好成矿条件,找矿远景广阔,需要深度挖掘分析。

The types of copper deposits in Tianshan and Beishan metallogenic belts mainly include intrusive rocks,marine volcanoes,sedimentary rocks,etc.the formation and evolution stages of copper deposits in this area include Precambrian,Late Paleozoic,early Paleozoic and Mesozoic Cenozoic.The source bed and the specific metallogenic structure can promote the rapid mineralization of the strata.The main forms of ore control are the regional tectonic environment.Volcanic rocks,regional faults,mineralization and intrusive rock factors are closely related to copper deposits.Therefore,the metallogenic belt has good metallogenic conditions and broad prospecting prospects,which requires deep excavation and analysis.
