贵州赫章铁矿包括铁矿山和菜园子两个沉积改造菱铁矿床.菱铁矿的赋存部位严格受一定地层层位及其相应的构造部位控制.地壳的构造运动可以为原生沉积菱铁矿床或含铁岩石提供改造动力来源;同时构造变形还为菱铁矿的就地改造富集提供了构造空间,使沉积改造的菱铁矿体能赋存在一定层位中更为有利的构造部位.构造应力场的分析与研究是地质力学的一个重要组成部分,运用地质力学的观点分析矿田、矿床的构造应力场将有助于对控矿构造的深入研究,这不仅对内生矿产有一定意义,通过对贵州西
The Hezhang Iron Mine in Guizhou Province includes two deposits of iron ore mines and Caiyuanzi altered siderite.The occurrence of siderite is strictly controlled by certain stratigraphic layers and their corresponding structural parts.The tectonic movement of the crust can be primary deposition Siderite deposits or iron-bearing rocks provide a source of retrofitting power. At the same time, structural deformation also provides structural space for in-situ reforming and enrichment of siderite so that the altered siderite ore body can be favored in a certain horizon Tectonic parts.The tectonic stress field analysis and research is an important part of geomechanics. Analyzing the tectonic stress field of orefields and ore deposits from the viewpoint of geomechanics will be helpful for the further study of ore-controlling structure. Minerals have some significance, through the west of Guizhou
