鄂西震旦系及铅锌矿关系初步研究

Preliminary Study on the Relationship between Sinian System and Lead-zinc Ore in Western Hubei

鄂西地区位于靠近扬子与秦岭边界断裂—青峰断裂以南的扬子准地台,是中国重要的成矿带-湘西—鄂西成矿带的主要组成部分。本文介绍了鄂西地区的地质背景及地区震旦系含矿地层层位与岩石类型,并且探究了鄂西地区铅锌矿的矿床类型,最后通过对含矿层在剖面中的位置及层位递变的分析,从而预测鄂西震旦系地层的含矿点的找矿前景。

The western Hubei region is located on the Yangtze platform which close to The boundary fault structure of Yangtze platform and Qinling mountains-South of the Qingfeng fault,and is an important part of the metallogenic belt-Western Hunan-Western Hubei metallogenic belt in China.This paper introduces the geological background of western Hubei,the Mineral-bearing strata position and the rock types of Sinian System,also explore the deposit type of lead-zinc ore in western Hubei.Finally,through the analysis of the position of the ore-bearing strata in the profile and Stratigraphic transmutation,it can be concluded that the north of Sinian strata in western Hubei have much exploration prospects.
