瞬变电磁法在排山楼金矿床勘查中的应用

Application of Transient Electromagnetic Method in The Exploration of Paishanlou Gold Deposit

辽宁排山楼金矿床为受韧性剪切带构造体系控制的大型金矿床,含矿构造带与围岩电阻率差异明显,具备瞬变电磁法进行勘探的物理前提。通过在本区开展瞬变电磁法探矿工作,建立瞬变电磁法圈定含矿构造带的异常解译准则,以期期望为排山楼金矿床深部及外围探矿提供有效参考。

Paishanlou gold deposit in Liaoning province was a large gold deposit controlled by the ductile shear zone tectonic system, and there existed the physical premise of transient electromagnetic method because of the obvious difference of resistivity between Ore structural belt and the surrounding rock. Through the transient electromagnetic method prospecting work in the district, the paper established anomaly interpretation criterion of delineating ore structural belt in transient electromagnetic method, and hoped to provide the effective reference for the deep and periphery prospecting of Paishanlou gold deposit.
