青海省茶五陇地区地质特征与成矿探讨

Geological characteristics and metallogenic discussion in Chawulong district of Qinghai Province

为了研究茶五陇地区成矿前景,在对区域成矿地质背景研究的基础上,结合野外地质及前人研究成果,采用地质、物化探综合分析的方法,对研究区地层、构造、变质作用、物化探等特征以及与邻区矿床成因对比进行了综合分析。分析结果认为,研究区受断裂控制,断裂是成矿的主导因素;后期热液蚀变主要出现在火山机构和断裂构造带上,含矿火山岩经热液蚀变而得到进一步聚集;具有寻找火山热液型铜多金属矿较好的找矿前景。

In order to study the metallogenetic prospecting in Chawulong district, on the basis of researching the background of the regional geological minerals and geology, combined the field geology with forefathers, research achievements, adopt to the comprehensive analysis method of geology and geophysical geochemical data, to research the characteristics of stratum, structure, metamorphism and geophysical geochemical data in the researc hing district. As well as comprehensive analysis for the comparison of the deposit formative factors in neighboring region. That the research indicates： the study area is controlled by fracture, and the fracture is the main factor of mineralization. In the later period, hydrothermal alteration mainly appears to the volcanic edifice and fractured tectonic belt, the volcanic with minerals is alternated by hydrothermal solution and got further aggregation, and it has the better prospecting potential of looking for the volcanic hydrothermal copper poly-metallic deposit.
