广域电磁法在河洼多金属矿勘查中的应用

The application of the wide field electromagnetic method in the exploration of the Hewa polymetallic ore deposit

在辽宁河洼地区多金属矿近年来地质资源勘查认识的基础上,利用广域电磁法对该区成矿有利地质界面进行勘查,勘探深度及精度较以往工作有了较大提升,对该地区深部矿产资源勘查意义重大,为河洼地区多金属矿成矿理论研究、辽东地区金矿成矿模型建立等方面提供了较准确的地球物理依据。

The resource exploration of Hewa area in Liaoning Province was carried out.On the basis of the understanding obtained,the wide field electromagnetic method was used to explore the favorable geological interface for mineralization in this area.The exploration depth and accuracy were greatly improved comparing with the previous work,which was of great significance to the exploration of deep mineral resources in this area.It is the theoretical study of polymetallic ore formation in Hewa area and the gold mineralization model in eastern Liaoning.The establishment of the metallogenic model provides a more accurate geophysical basis.
