摘　　要：采用激电测深法,对研究区进行了矿产成矿规律勘查,测区内发现了8个电阻率异常与6个视极化率异常,推测了5条构造带,指导了地质找矿。视电阻率异常D_(ρ-2)、D_(ρ-3)、D_(ρ-5)、D_(ρ-6)与视极化率激电异常D_(η-2)、D_(η-4)构造带的走向基本一致,位于区内成矿有利部位,推断为矿致异常。通过电法激电研究对成矿规律和找矿方法的研究,以寻找萤石矿物矿床为主要目的,圈定含矿构造,为进一步矿产研究提供依据。Using the IP sounding method,the mineral mineralization regularity of the study area was investigated.8 resistivity anomalies and 6 apparent polarizability anomalies were found in the survey area,and 5 structural belts were inferred,which guided the geological prospecting.The apparent resistivity anomalies D_(ρ-2),D_(ρ-3),D_(ρ-5),and D_(ρ-6) are basically the same as the apparent polarizability IP anomalies D_(η-2) and D_(η-4) structural belts,and they are located in favorable areas for metallization in the area.Anomalies caused by mines.Through the study of the ore-forming laws and prospecting method through the study of electrical induction,the main purpose is to find the fluorite mineral deposit,and the ore-bearing structure is delineated to provide the basis for further mineral research.
