| 文章简述了激电测深在江西某矿集区穹隆构造勘查中的应用。通过在穹隆构造上布设剖面，开展大功率对称四极激电测深，结合矿集区岩矿石标本的电参数以及地质资料，对测深剖面进行了电阻率/极化率2.5维反演与推断解释，根据不同电性特征，成果大致反映了该区的地电结构分层情况，对该穹隆构造的地层单元界线划分有所体现，激电异常对深部寻找隐伏岩体具有一定地质指示意义。 |
| 英文摘要: |
| IP sounding is applied to exploration of a dome in an ore deposit-clustered area in Jiangxi Province. Profiles are laid out over the dome and high power symmetrical quadrupole electrical sounding conducted. According to electrical parameters of rock samples and geological data of the ore deposit-clustered area 2.5 D inversion of resistivity and polarization of the sounding profiles are carried out and deduction are conducted. The results show different electrical properties and generally reflect geological and electrical layering of the area and boundaries of stratigraphic units in the dome are shown. The IP anomly is significant to indicate the concealed intrusion in some way. |
