摘　　要：采用对称四极激电测深对罗桥矿区进行研究,结果显示1号剖面视极化率两端低,中间高;视电阻率西端低、东端高;大致查明不同电性体的垂向分布情况。佘田桥组泥质灰岩与泥灰岩表现出低阻低极化的特征;泥盆系地层中泥灰岩和灰岩中碳质、泥质的局部富集表现出低阻高极化的特征;金属硫化矿物显示出高阻低极化的特性。激电测深方法还推断出隐伏断层位置及岩体与围岩接触带。In this paper, we use Induced Polarization Sounding to study the Luoqiao Tin - polymetallic Deposit, the results show that to No.1 section, the apparent polarizability is low in the east and west end, higher in the middle; intermediate and high; apparent resistivity is low in the west and higher in the east. Based on this we generally identified vertical distribution of different electrical body. Argillaceous limestone and marl of Shetianqiao formation Characterized by low resistance and low polarization; Local enrichment of carbon and clay minerals in marl and limestone of The Devonian strata present the characteristics of low resistivity and high polarization. Metal sulfide ore shows the characteristics of high resistance and low polarization. We conclude the location of concealed fault and rock contact zone by Induced Polarization Sounding.
