| 摘 要： | 东昆仑地区处于中朝、塔里木-柴达木、扬子和印度板块的拼合部位，元古宙以来经历了多期次的裂解和拼合。该区以Au、Co、Cu、Pb、Zn、Hg、Sb、As元素组合为特征，其中多处已证实为矿致异常，共发现矿床、矿点等198处，初步显示了良好的找矿前景。目前在大干沟一带已发现铜多金属矿化带一条、金锑含矿构造蚀变带一条。矿化特征基本一致，均赋存于中三叠统闹仓坚沟组北西西向脆韧性剪切带内及两侧的灰白-烟灰色方解石石英脉内，且具有南侧金锑矿化、北侧铜多金属矿化的分带特征。

| Abstract: | The East Kunlun area is located at the suture zone of Sino-Korean Plate, Tarim-Qaidam Plate, Yangtze Plate and India Plate. The special tectonic structural location decided its tectonic evolution being very complicated and distinctive. The geochemical anomalies in this area composed by Au-Co-Cu-Pb-Zn-Hg-Sb-As elements and most of them have been confirmed as anomalies related to mineral deposit. 198 ore deposits and ore spots have been found in this area. This showed a favorable ore-searching prospect. Total 6 ore deposits were discovered at Dagangou zone, including a copper multi-metal mineral belt and a gold-antimony ore-bearing structural alteration belt. Their mineralization characteristics are basically same. The ore deposit occurred in the Middle Triassic Naocangjiangou Formation west-northwest brittle-ductile shear zone and ashen-gray calcite quarts vein at the both sides of shear zone. |
