保国铁矿边家沟矿区构造控矿特征及找矿前景分析
|
摘要
随着保有资源储量减少,服务年限不断缩短,保国铁矿目前已属于危机矿山。为解决矿山资源问题,2014年完成了"辽宁省北票保国铁矿接替资源勘查项目",对包括边家沟矿区在内的3个矿区进行了地质勘查工作,对其铁矿控矿特征、成矿规律及找矿前景进行了综合研究,为矿山后续发展提供了依据和指导。保国铁矿边家沟矿区具明显构造控矿特征,矿区内含矿岩系被2条北东向逆冲断层切割,以构造推覆体的形式与下部侏罗系地层断层接触。经地表地质测量及深部钻探工程验证,边家沟矿区深部已不存在工业铁矿体,今后找矿工作应重点布置于楔形构造推覆体的北东端开放地段。
With the reduction of reserves of resources and the shortening of service years,Baoguo Iron Mine is now a crisis mine. In order to solve the problem of mine resources,in 2014, the "Exploration Project for the Replacement Resources of Baoguo Iron Mine in Liaoning Province" was completed,and geological exploration work was carried out on three mining areas including the Bianjiagou mining area. Comprehensive research on iron ore control characteristic, metallogenic regularity and prospecting prospects provides basis and guidance for the subsequent development of the mine.Bianjiagou mining area of Baoguo Iron Mine has obvious tectonic ore-controlling characteristics.The ore-bearing rock series in the mining area is cut by two NE-trending thrust faults and is in contact with the Lower Jurassic stratum fault in the form of tectonic nappe.According to the surface geological survey and deep drilling engineering verification,there is no industrial iron ore body in the deep part of the Bianjiagou mining area.In the future,the prospecting work should be arranged in the open section of the northeast end of the wedge-shaped structure nappe.
