Abstract The Chating copper-gold deposit in Xuancheng City is the first discovered porphyry type copper-gold deposit in Southeastern Anhui Province. In recent years, some new achievements are got by a series of geophysical survey and verification works of geophysical anomalies. The copper polymetallic deposits in the area are closely related to magmatic activity. The geomagnetic anomalies are caused by intermediate-acid intrusive rocks, and gravity anomalies are caused by carbonate rocks. Besides, the low resistivity anomalies in CSAMT are caused by pyrite and chalcopyrite. The Chating copper-gold deposit are characterized by low magnetic, high gravity and low resistivity in CSAMT. The new gold-bearing cryptoexplosive breccia and lead-zinc ore bodies have been found in the deep prospecting in the periphery of Chating copper-gold mining area, based on the above comprehensive prospecting informations, which indicates the prospecting direction and provide further prospecting breakthrough idea in the periphery of Chating copper-gold mining area.

Key words： copper-gold deposit cryptoexplosive breccia magnetic gravity CSAMT mineral prospecting potential Xuancheng Chating
