| 摘 要： | 新疆西昆仑特格里曼苏铜矿处于西昆北恰尔隆-库尔良构造分区克孜勒陶组（D2kz）中，矿体呈层状、似层状及透镜状产出，受地层控制。浅色砂岩与紫色砂岩的交互带是铜矿产出的有利部位。通过对特格里曼苏砂岩型铜矿的调查研究，认为其含铜建造原生色以紫红色为主，浅色层为特殊的沉积体。含铜建造中浅紫交互带可分为成岩期、后生期及改造期三类：成岩期主要受沉积作用及孔隙水影响，使含矿建造中上部富集成矿；后生期主要受构造作用及建造水影响，“紫化”过程中在浅紫过渡带富集成矿；改造期主要受断裂及构造热液影响，在构造交汇部位富集成矿。

| Abstract: | The Teglinmansu copper deposit of Xinjiang is located in the northern Qia''erlong-Kuerliang tectonic region of the West Kunlun orogenic belt, where ore bodies occur in the Devonian Keziletao Formation (D2kz) with layered and lenticular forms, controlled by strata. The interaction zone between light-color sandstone and purple sandstone is a favorable deposit position of the copper. Based on detail investigations on the Teglimansu sandstone-type copper deposit, we suggest that the original color of copper is mainly purple red, whereas the light layers are the special sedimentary bodies. The mineralization of the light-purple interaction zone in copper construction can be divided into three types: diagenetic, post-diagenetic and reconstruction periods; the mineralization during the diagenetic period is mainly controlled by sedimentation and pore water/fluids, which allowed the copper to be enriched in the upper and middle parts of the formation. The later period was affected by tectonic activity and formation fluids. During the purple-becoming process, enrichment and mineralization occurred in the light-purple transition zone. And during the reconstruction period, the mineralization commonly occurred in tectonic junction controlled by faults and tectonic hydrothermal fluids. |
