The Bairong copper deposit of Tibet is a porphyry-type deposit discovered recently. The key for the further exploration is to identify burial depth

morphology and mineral body distribution of monzogranite porphyry in the northern part of the deep mine. An EH4 continuous conductivity profile was measured at the favorable metallogenic district in the northern part of Bairong copper deposit.The electrical difference in the mininginduced rock(ore) was used to interpret the comprehensive geology of quasi-two-dimensional contour section through two-dimensional qualitative and quantitative inversion combined with the geological model of the deposit. The results showed that the two-dimensional apparent resistivity - depth sectional drawing can clearly reflect the underground different geologic body of elaborate resistivity structure. The whole section can be divided into five kinds of different electrical body，among whichlayerⅣ of high resistance is speculated for concealed monzogranite porphyry body; Layer Ⅲof medium resistance is speculated for quartz monzonitic porphyry；Layer Ⅴof low resistance body consists of three parts

suggesting volcanic hydrothermal and porphyry Cu

Mo mineralization (body).
