Deep ore prospecting potential analysis of Bamaoshan copper deposit in southern Luzong volcanic basin

The Bamaoshan copper deposit, located in the south of Luzhong volcanic basin, is the representative of vein belt altered rock type copper deposit. Previous researches showed that the deep part of this area has the potential for porphyry copper deposits. In order to further clarify the ore-prospecting potential in the deep part of this area, the authors have focused on the main ore-controlling factors of porphyry and hydrothermal copper deposits in this area, including rock masses, fractures, and contact zones. High-precision magnetic methods and controlled source audio magnetotelluric sounding (CSAMT) results were utilized to analyze the distribution, occurrence, deep-seated morphology, and characteristics of the contact zone with surrounding rocks. Base on there researches, through the analogy with the geological and geophysical anomaly characteristics of the Shaxi porphyry copper deposit, the authors pointed out the prospecting direction and favorable prospecting sites in the study area, which could provide some ideas and basis for further prospecting.
