摘要 东昆仑地区经历了多期次的构造演化和岩浆活动,其中早古生代和晚古生代-早中生代时期的洋-陆转换过程对区内地层、构造、岩浆活动和成矿具有决定作用.早古生代时期的喷气-喷流型矿床组合和晚古生代-早中生代时期的造山型矿床组合最为重要.万宝沟群、纳赤台群,马尔争组,下巴颜喀拉群地层控制着喷气-喷流型矿床组合的空间分布.晚华力西-印支期及燕山期侵入岩体控制了造山型矿床的分布.深断裂带、大型剪切带及其旁侧的褶皱及断裂-裂隙系统控制矿带、矿区、矿床和矿体. The eastern Kunlun area has undergone different times' structural evolution and magmatic activities. Of all, the land-ocean transformation process of the early Paleozoic era and late Paleozoic era to early Mesozoic era has played a crucial role for strata, structure, magamitic activity and mineralization in the area. The exhalation-spout type deposits of the early Paleozoic era and the orogenic type deposits of the late Paleozoic to early Mesozoic era are the most important deposit groups. The spatial distribution of exhalation-spout type deposits are controlled by the Wanbaogou Group, Nachitai Group, Maerzheng Group and Xiabayanlela Group strata. The intrusive rock bodies of the late Variscan to Indosinian and Yanshanian dominate the distribution of the orogenic type deposits. The ore belts, mining area, deposits and ore-bodies are all controlled by the deep faults, large scale shear zones and the fold and fault-crack system aside.
