摘要
研究区内广布的富金元古宇地层是金矿集中区形成的基础,多期次的强烈岩浆活动为金矿集中区的形成提供了极为丰富的成矿流体和矿质来源,脆韧性剪切带为矿液流通和汇聚提供了有利空间。在区内的脆韧性剪切带中分布有Ⅰ矿带和Ⅱ矿带,带内发育硅化、绢云母化、黄铁矿化、绿泥石化、碳酸盐化、纤闪石化、高岭土化蚀变,金多金属矿化主要与硅化、绢云母化、绿泥石化、黄铁矿化关系密切。目前已提交金资源量约8.94t,银金属量约247.02t,铅金属量约6.45万t,锌金属量约5.23万t。综合分析该区地质矿化特征和控矿因素认为,研究区成矿条件优越,找矿潜力巨大,通过开展进一步勘查工作有望达到大型金多金属矿床规模。
The widely exposed Proterozoic strata rich in gold and multiple intense magmatic activities in east Kunlun, Qinghai are the basis for the formation of dense area of gold mineral deposits. The brittle-ductile shear zone provides favorable space for the flow and convergence of the ore fluids. Silicification, sericitization, pyritization, chloritization, carbonation, fibrillation and Kaolinization are well developed in the Haxiwa Au-polymetallic deposit, but Au-polymetallic mineralization is only related to silicification, sericitization, chloritization and pyritization. Existing resources are 8.94 t Au, 247.02 t Ag, 64500 t Pb and 52300 t Zn. This area has good ore-forming geological conditions and great prospecting potential.
