地质物探综合方法在辽宁张家堡地区隐伏铁矿普查中的应用

辽宁张家堡地区铁矿资源比较丰富,沿北北东向太古宙深变质岩带有20余个小型铁矿床(点)分布,铁矿体呈薄层状,但矿体倾向、埋深不一。文章通过在该地区开展地质物探多方法普查,确定矿体倾向和矿体埋深,结合钻探深部验证,为在该区寻找同类型隐伏铁矿体打下了基础。

Application of comprehensive method of geological exploration and geophysical method in prospecting the concealed iron orebody in Zhangjiapu area, Liaoning

There is rich iron mineral resources in Zhangjiapu area, Liaoning Province, and more than 20 small-sized iron ore deposits (occurrences) located along NE-striking Archean metamorphic rocks. The iron orebodies are distributed in forms of thin layer, but have different dipping tendency and varied buried depth. Based on the results of geophysical methods, the dipping tendency and buried depth of concealed iron orebodies were interpreted for the test drilling, which provides the basis for prospecting the similar iron deposits in this area.
