新疆卡拉塔格红山铜金矿床地质特征及成因初探
|
摘要
红山铜金矿床位于东天山大南湖—头苏泉岛弧带北部的卡拉塔格地区,以硫酸盐类铜金矿为主,硅化脉状铜金矿为次,赋存于大柳沟组火山岩-次火山岩中,受区域NWW向构造控制。红山铜金矿床是一种浅成火山热液型铜矿床,蚀变以火山岩的酸性淋滤带和绢云母-硅化为显著特征,远矿蚀变为青磐岩化,具明显的分带性。通过对矿床地质特征总结分析,结合他人研究成果,认为红山铜金矿床于中生代中低温热液体系下形成,后期由于地壳隆起遭到剥蚀,硫化物在地表氧化迁移汇集,沿围岩构造裂隙渗透、淋滤,最终形成现在的红山铜金矿。
The Hongshan Cu-Au deposit is hosted in the volcanic rocks of the Daliugou Group in the Kalatage area of the Dananhu-Tousuquan island arc belt,Eastern Tianshan Mountains.The main orebodies of the deposit are made of sulfate oxides,the rest are vein Cu-Au orebodies controlled by NW trending fault structure.The Hongshan Cu-Au deposit,an epithermal volcanic copper type deposit,has obvious alteration zone mainly made of silication-serricitization and farther propylitization.Based on the summary and analysis of the geological characteristics of the deposit and combined with other people's research previous results,it is considered that the Hongshan Cu-Au deposit formed initially in epithermal volcanic mineralization system in Mesozoic era.Later,due to the erosion of crustal uplift,the sulfides suffered the courses by oxidation,migration and concentration on earth's surface,then permeated along the surrounding rock structure and leached,the Hongshan Cu-Au deposit formed ultimately.
