摘要
This paper applies the dual-frequency IP method (Dipole-Dipole configration) to rapid prospecting of gold ores in the Lizi area of Gansu Province,and discusses the characteristics of the electrical parameters for different rock samples. The result shows that the dual-frequency IP method and the equipment can be utilized effectively in the difficult terrain and forest areas of the Tianshui section of the north Qinling Mountain. It owns advantages for prospecting the metal sulfide gold deposits with high efficiency,low cost and ideal results. The finite element optimization method of frequency digital inversion technology can effectively improve the shock of the abnormal inference and interpretation,and to determine its position in space. The anomaly verification shows that the anomalous bodies correspond to the gold ore bodies well,and this method is worthy to be popularized.
