摘要

 In order to search for deep concealed ore bodies in the eastern part of Jilin Province, explored Shimadong molybdenum mine of Helong City, Jilin Province by IP intermediate gradient and sounding of Induced polarization method and found that the high polarization and low resistance anomaly of polarization rate of 2.00% ~5.18%, resistivity of  ≤ 2 000 Ω.m  Abnormal body symmetry quadrupole induced polarization sounding device results showed that: 11 exploration depth of the top surface of the body linearly polarized 15 ～ 30 m, bottom depth > 500 m; verified by the drilling works, molybdenum ore body shape, occurrence, top and bottom of the depth of interpretation of the results are basically consistent with the anomaly. The results show that the method can quickly identify and delineate IP anomaly, understand the depth of polarization and spatial occurrence and provide adequate guidance to engineering verification basis.
