新疆库木库里盆地砂(砾)岩型铜矿地质特征及其控矿条件分析

Geological features and ore-controlling conditions of sand stone (conglomerate)copper deposit in Kumukuli basin, Xinjiang

摘要: 新疆库木库里盆地砂(砾)岩型铜矿位于东昆仑造山带西段,含矿地层为古近系渐新统石马沟组、新近系中新统石壁梁组与上新统红石梁组。铜矿带东西长约170km,南北宽10～60km。已发现铜矿体20多条,矿化体70多条。铜矿化主要受构造、岩性、岩相古地理、古气候等因素控制。矿床属陆相砂砾岩型铜矿。

Abstract: The Kumukuli sandst one (conglomerate) copper deposit is located in western segment of East Kunlun orogenic belt,Xinjiang.The strata of ore-bearing are composed of Oligocene Shimagou Formation,Miocene Shibiliang Formation and Pliocene Hong shiliang Formation.The orebelt is 170 km in length of EW and 10-60 km in width of SN.The mineralization was controlled by structures,lithology,lithofacies and paleog eography and paleoclimate.The mineralization type is continental sandstone (conglomerate) copper deposit.
