In order to find deep concealed orebodies in eastern J ilin with thick covers on Earth, the induced polarization method to sweep the surface of middle gradient installment has been used in Liushengdian molybdenum ore investigation in Antu, which discovers a high polarization and low resistivity anomaly with 1.88%��4.61% polarization and 300��500 ٷm resistivity. The IP sounding results of symmetrical quadrupole installment on anomalous body show that the polarization body top surface buried depth of exploration line No.3 is 20��30 m, bottom surface buried depth is 150��170 m, and the polarization body top surface buried dep th of exploration line No.11 is 25��65 m, bottom surface buried depth > 200 m. Through the confirmation of exploration engineering, the molybdenum ore body's shape, occurrence, buried depth of top and bottom plates are basically agreed with anomaly interpretation results.
