新疆莎车县也迪盖塔木铜矿床地质特征及成因探讨

摘要

Yedigaitam copper mining area is located in the west of Kunlun Mountains, the north of Karakorum-kunlun Mountains and the west of Tarim Basin. Ore body is mainly composed of two parallel veins belt. by the preliminary geological prospecting work, four Copper ore (mineralized) bodies were found in this area. Copper ore bodies occur in celadon calcareous sandstone formation of Qingbaikou system Sukuleke Group (sl), and the surrounding rock is the purple quartz sandstone. Copper ore bodies are obviously controlled by green calcareous sandstone formation, and the copper deposit types are comprehensively defined as sedimentary metamorphic sandstone type.%也迪盖塔木铜矿区地处昆仑山西段、喀喇昆仑山北段及塔里木盆地西部的结合部位。矿体主要由两条平行的脉带组成，铜矿体在脉带内局部尖灭再现，经初步地质勘查工作，区内共发现4条铜矿（化）体。铜矿体赋存在青白口系苏库罗克群（Qb sl）的NNW向灰绿色钙质砂岩地层中，围岩为紫红色石英砂岩，铜矿体受绿色钙质砂岩地层控制明显，综合分析认为该区矿床成因类型为沉积变质砂岩型铜矿。
