| 摘 要： | 随着找矿、勘探与开发生产实践的不断深入,表露矿与浅部矿渐趋减少,找矿难度逐渐增大,找到一种简捷、迅速的勘查、探矿方式,迫在眉睫.根据实践证明,甚低频电磁法是较为理想的选择.在运用甚低频电磁法时,通过对所测数据进行Fraser滤波等技术处理,并且结合矿区地质研究控矿规律及矿体赋存规律,从而有效地圈定掩盖区异常地质体及其产状和展布方向,预测矿体空间赋存部位,为深部找矿提供依据. |

| Abstract: | With long-term continuous search for mineral resources in the past,the opportunity in discovering the outcropped and shallow-seated deposits becomes increasingly difficult.Therefore,new methodologies in finding the concealed ores under overburden are very important and greatly required in present and future mineral exploration activities.Based on our practice,the VLF-EM method is a cost-effective and useful geophysical technology in delineating blind orebodies under cover.Through a systematic VLF-EM survey in a specific potential area,some preferred VLF anomalies that may correspond mineralized structures would be discovered.By geological modeling and cross-testing,those discovered anomalies could become potential targets for further detailed geological exploration. |
