摘　　要：介绍了云南某金矿矿矿区地质构造,在充分研究工作区的地质、地球物理特征前提下,采用了大功率激发极化中梯装置和激发极化测深相结合的方法进行勘察。并对扫面和测深的成果进行分析,进行了推断解释。通过在该区开展激电测深工作,圈定了与成矿有关的构造破碎带的分布、走向,结合地质,为深入开展地质找矿工作提供了有利的依据。在5线500m处布置的测深点,其测量结果与已知的钻孔成果相符合,验证了该方法的有效性。This paper describes the geological structure of a gold mining area, under the premise of the full study on geological and geophysical characteristics of the workspace, uses the method with the combination of high-power excitation polarization gradient device and induced polarization sounding to carry out inspections, and analyzes the sweeping surface and sounding results, then conducts inference and interpretation. Through the IP sounding work in the area, this paper delineates the distribution and direction of bearing fractured zone related to mineralization, providing a favorable basis to carry out the geological prospecting work. The measurement results of the sounding point set in the 5-line 500m are consistent with the known drilling resu｜ts, so it verifies the effectiveness of the method.
