强家沟矿区构造控矿浅析

Analysis on Structural Control of Mine in Qiangjiagou Mining Area

本区经历过多期次构造运动,构造极其复杂,属于刚性较强的地块,以脆脆性断裂构造发育为特征,早期的构造形迹常被后期的构造形迹改造或掩盖,大致遵循印支~燕山期的华夏系和新华夏系(NE或NNE)构造发育的基本格局,早期基底构造为北西向、东西向断裂,后期控矿构造为北北东向断裂,今天,主要就已有现状和以后发展规律做简要分析和推断。

This area has experienced many stages of tectonic movements,and its structure is extremely complex.It belongs to a relatively rigid block and is characterized by the development of brittle fracture structures.The early tectonic traces are often reconstructed or concealed by later structural traces.The basic pattern of the tectonic development of the Huaxia and Xinhuaxia(NE or NNE)in the Yanshanian period,the early basement structure is the northwestward and east-west faults,and the later ore-controlling structure is the north-north-east fault.Today,mainly Brief analysis and inference are made on the status quo and the law of future development.
