甘蒙北山地区板块构造演化与铜多金属矿成矿系列研究

结合板块构造理论和成系列概念，提出了成矿系列新的研究方法。甘蒙北山地区位于哈萨克斯坦板块和塔里木-中朝板块交汇部位，其板块构造演化分为前震旦纪古板块活动时期、震旦一泥盆纪现代体制板块活动时期和石炭-二叠纪裂谷活动时期，不同构造单元演化阶段控制了不同的含矿建造、成矿作用时空分布及演化序列和矿床共生组合。按照板块构造演化及其与铜多金属矿成矿作用时空分布和成矿作用演化序列的关系，划分出北山地区铜多金属矿古大陆区（缘）成矿系列，洋缘火山带成矿系列、岛弧-弧后盆地成矿系列和裂谷带成矿系列。

The Evolution of Plate Tectonic and Its Copper and Multi-metal Metallogenic Series in Beishan Region

The Beishan region is located at the junction of Tarim-SK(Sino-Korea) plate and Hazakstan plate.Its plate evolution can be divided into three stages: AnZ ancient-plate stage(ancient-continent accretion),Z-D plate stage(plate expansion and subduction )and C-P rift stage. The mineral-bearing formation, the deposit distribution in space-time and their metallogenic sequence in this area are controlled by different plate tectonic units and their evolution stages. By examining the relationship between plate tectonic evolution stage and copper and multi-metal mineralization distribution in space-time as well as their sequence, a new conception of the metallogenic series is suggested on the basis of the plate tectonics, and the metallogenic series in Beishan region are described. there are four types of metallogenic series based respectively on the (ancient)continental margin, subduction belt,volcanic belt in the nascent basin and rift.
