| 中文摘要: |
| 青海省东昆仑成矿带由昆北裂陷槽区、昆中花岗—变质杂岩带、昆南复合拼合带组成,各带形成了不同的地球物理、地球化学特征。其历经元古宙大陆边缘阶段,晚奥陶世裂陷槽阶段,晚古生代多岛洋活动大陆边缘阶段和中生代中—晚期弧后拼合—增生造山阶段4个构造演化阶段。成矿集中在印支期、加里东期,近东西向3条矿带形成不同类型矿产的分布。不同的演化阶段形成有色、贵金属矿成矿系列。 |
| 英文摘要: |
| The eastern Kunlun metallogenic belt, located in Qinghai Province, is composed of northern Kunlun aulacogen belt, middle Kunlun granitic metamorphic complex belt and southern Kunlun composite merging zone, each with different geophysical and geochemical characteristics. It passed through four tectonic evolution stages as followings:Late Proterozoic continental margin stage, Late Ordovician aulacogen stage, Late Paleozoic active multi- islands and sea continental margin stage and Middle-late Mesozoic back-arc amalgamation-and accretionary orogenesis stage. The mineralization is mainly formed in the Indonian and Caledonian periods, and outlined as three near EW-trending mineralization zones with different types of mineral deposits, and thus the metallogenetic series were formed by different tectonic evolution stages. |
