浅析滚艾尔沟铜多金属矿床成因

Analysis of the genesis of the copper polymetallic deposit in the hobbing Eyre gully

滚艾尔沟铜多金属矿位于柴北缘成矿带,分析和研究该区的地球化学特征及成因类型,对于该区进一步找矿工作具有重要的指导意义。针对区内含矿长英质片岩实施LA-ICP-MS锆石U-Pb定年法,对其铅同位素以及硫同位素进行相关的测定工作。结合本区地质、矿化蚀变特征,初步认为在本区主要存在变质热液型和构造蚀变岩型等两种成因类型,可为下一步工作部署提供了重要依据。

The rolling Eyre Gou copper polymetallic ore is located in the northern margin of the Qaidam metallogenic belt. The analysis and study of the geochemical characteristics and genetic types of this area have important guiding significance for further prospecting in this area. The LA-ICP-MS zircon U-Pb dating method is applied to determine the lead isotopes and sulfur isotopes in the ore bearing felsic schist. According to the characteristics of geological and mineralized alteration in this area, it is preliminarily believed that there are mainly two types of genetic types, such as metamorphic hydrothermal and tectonic alteration rock types in this area, which can provide important basis for the next work deployment.
