关于新疆伊热达坂铅锌矿矿化与围岩蚀变关系的探讨

On Relation between Mineralization and Wallrock Alteration in the Yiredaban Pb-Zn Deposit,Xinjiang

伊热达坂铅锌矿床位于东天山地区,为地层、构造、岩浆岩共同控制的气水-热液交代型铅锌矿床。矿区围岩蚀变发育,主要类型有硅化、萤石化、孔雀石化、重晶石化,方解石化等。以野外观察和分析数据为基础,运用因子分析,对矿区的铅矿化与主要围岩蚀变的关系进行了分析探讨,认为硅化、萤石化、孔雀石化与铅锌的成矿关系最为密切,蚀变总强度与矿化强度呈正相关。

The Yiredaban Pb-Zn deposit is a vaporous water-hydrothermal metasomatic deposit which is controlled by stratigraphic horizon,structure and magmatic rock.Wallrock alterations such as silicification,fluoritization,malachitization,baratization and calcitization are well developed.This paper deals with the relation between the mineralization and the wallrock alterations by factor analysis and believes that silicification,fluoritization and malachitization are in close relationship with the mineralization.
