摘要
彩花沟矿区域上属塔里木板块与准噶尔板块缝合带南侧,钨铜矿体赋存于泥盆系下统阿尔彼什麦布拉克组下亚组第二岩性段(D_(1)a^(a-2))与华力西晚期二云二长花岗岩外接触带及其外侧150米范围内的似层状矽卡岩中,矿体受火山喷流沉积层状-似层状矽卡岩的控制,受岩体侵位接触交代矽卡岩化的迭加,为沉积改造型钨铜硫铁矿;属火山喷发沉积-区域变质改造-接触交代变质叠加形成钨铜硫铁矿床。
The Caihuagou mining area belongs to the southern side of the suture zone between the Tarim Plate and the Junggar Plate.The tungsten copper ore body is located in the second lithological segment (D_1a~(a-2)) of the Lower Devonian Albishmabulake Formation and the outer contact zone of the Late Hualixi Eryun Erchang granite,as well as the layered siliceous rock within a range of 150 meters on the outer side.The ore body is controlled by volcanic eruption sedimentary layered layered siliceous rock,and is superimposed by the intrusion contact metasomatic siliceous rock,forming a sedimentary modified tungsten copper pyrite;Belonging to volcanic eruptive sedimentation,regional metamorphic transformation,contact metasomatism and metamorphism,tungsten copper sulfide iron deposits were formed.
