| 摘 要： | 在地形复杂的山区选取合适的方法,准确、高效的探测地下深部矿体的赋存位置,是我们面临的挑战。应用先进便捷的高频大地电磁(HF-MT)测深系统Stratagem EH-4对桂北目标矿区进行电磁排列剖面测量。分别采用Bostick和快速松弛迭代反演方法对实测数据进行解释处理,经工程验证成果图件所标示断裂构造及矿体位置与实际地质情况吻合。该野外观测方法、技术及数据处理、解释方案值得在矿产资源勘察中推广应用。

| Abstract: | In the mountains area,we have to solve the problem that how to select appropriate method,accurately and effectively explore the burial condition and location of the deep mineral ore with complex terrain.Advanced and Convenient high-frequency magnetotelluric(HF-MT) sounding system Stratagem EH-4 was applied to electromagnetic array profile survey in target mining area of northern Guangxi.Bostick and Rapid Relaxation Iterative inversion method were used to interpret the observational data,and it has been verified by the mine works that location of faults and orebodies marked by resulting images are tally with the real geological conditions,which provide resource base for the continued production of the mine.This measurement technique and interpretation method should be popularized and applied in mineral resources exploration,especially in mountains area. |
