本文研究了陕西凤县铅桐山铅锌矿床构造变形及其地质地球化学特征。笔者从矿区褶皱变形、岩石有限应变测量、层滑断裂破碎带和矿体产出形态特征、含矿硅质岩特征、层滑破碎带铅锌元素分布、流体包裹体特征等方面分析了该矿床动力热液成矿特征,并提出了该矿床动力热液成矿模式。 通过动力热液成矿特征分析,本文结论是:构造动力作用不仅能形成一些变形构造,同时在适当条件下也能使破碎带金属物质活化转移并富集成矿,而且还能富集形成大型热液矿床——即动力热液形成矿床。这种新观点对认识该矿床成因和进一步找矿勘探等均有重要意义。
This paper studies the structural deformation and geo-geochemical characteristics of the Pb-Tongshan Pb-Zn deposit in Fengxian County, Shaanxi Province. Based on the analysis of fold deformation, finite strain measurement of rock, strata-slip fracture and ore body, morphological characteristics of ore-bearing siliceous rocks, distribution of lead and zinc elements in stratified faults and fluid inclusions, Hydrothermal mineralization characteristics and put forward the hydrothermal hydrothermal mineralization model. Based on the analysis of the hydrothermal mineralization characteristics, the conclusion of this paper is that the tectonic dynamic can not only form some deformation structures, but also activate and transfer the metal of the crushing zone and enrich the mineralization under appropriate conditions, and also enrich the formation of large heat Liquid deposits - that is, hydrothermal hydrothermal deposits. This new view is of great significance to understanding the genesis of this deposit and further prospecting exploration.
