辽东南金属矿勘查中广域电磁法应用效果

The application effect of WFEM in the exploration of metal deposits in the southeast of Liaoning Province

在辽宁东南部多个金属矿区运用广域电磁法进行测量研究,可对辽东南深部地层接触面以及构造发育等特征形成更清晰认识,通过对辽东古裂谷以及变质核杂岩的形成时间、岩石圈层隆升过程、动力学机制的深入了解,应用广域电磁法为该地区成矿、控矿作用和成矿机理等提供较准确的地球物理依据,对辽东南金属矿成矿模型建立以及深部矿产资源勘查具有重要意义。

By using the wide field electromagnetic method to measure and study many metal mines in the southeast of Liaoning Province,researchers can have a fairly clear understanding of the formation of deep strata contact surface and structural development in the southeast of Liaoning Province.Through the deep understanding of the formation time of the ancient rift and metamorphic core complex,the process of rock circle uplifting and dynamic mechanism in the east of Liaoning Province,the authors applied wide field electromagnetic method and provided more accurate geophysical basis for mineralization,ore control and metallogenic mechanism in this area,which is of great significance to the establishment of metallogenic model of metal deposits in southeast Liaoning Province and the exploration of deep mineral resources.
