青海省哈得尔甘南铜多金属矿地质特征及找矿标志

Geological characteristics and prospecting indicators of Hadergannan copper polymetallic deposit in Qinghai Province

矿区大地构造上属于祁漫塔格早古生代缝合带,主要基岩地层为晚石炭世缔敖苏组、晚三叠世鄂拉山组,北西向以及一系列伴随北西向断裂形成的层间断裂或破碎裂隙成为了热液活动和矿物质沉淀的场所,矿区北区为构造热液型矿床,南区为接触交代(矽卡岩)型矿床.多种找矿标志明显,研究结果对以后的地质勘查具有很重要的参考.

The tectonic structure of the mining area belongs to the Qimantag Early Paleozoic suture zone.The main bedrock strata are the Late Carboniferous Biaosu Formation and the Late Triassic Orashan Formation.The northwestern trend and a series of layers with northwestern fault Intermittent fractures or fractures have become a place for hydrothermal activity and mineral precipitation.The northern area of the mining area is a structural hydrothermal deposit,and the southern area is a contact metasomatism(skarn)type deposit.A variety of prospecting signs are obvious,and the research results have a very important reference for future geological exploration.
