摘要:
通过对舞阳铁矿田以往地质资料收集整理及野外调查,对该区构造格架特征进行了梳理,研究结果表明:本区位于鲁山背孜-舞阳出山复背斜构造的东段,以NW-SE向褶皱为主,物探重磁资料表明该区存在近南北向构造格架.将该区构造演化特征划分为4个期次,在主构造(第二期NW-SE向褶皱)形成后,第三期构造变形作用(NNE-SN)形成叠加褶皱,在构造的叠加部位,易形成埋深较浅的厚大矿体,对今后找矿工作具有一定的指导意义.
Abstract:
Wuyang iron deposits is located in the eastern part of Lushan Beizhi-Xiping Chushan fold belt and fold axial is NW-SE.There is a series of nearly NS fold in Wuyang iron deposits based on gravitational and magnetic anomalies.Based on past papers and data, according to the geological exploration, this paper summarizes structural framework and discusses tectonic evolution of Wuyang iron deposits, dividing this area into four sub-period.This study shows that structural superimposion between the main structure (NW-SE direction) and the third phase of structural deformation (NNE-SN direction) is important role in this area, and the iron deposits is formed on structural superimposion.It might play a certain guidance for future prospecting work.
