Three dimensional audio-frequency magnetotellurics prospecting for copper deposit in Shujiadian, Tongling, Anhui Province
摘要
Abstract
Audio-frequency magnetotelluric method and 3D inversion code were used to study the porphyry copper deposit in Shujiadian, Tongling, Anhui Province. A 3D inversion was demanded. Sites data were selected and frequencies were decided, and the WSINV3DMT code was used with a reasonable parameter design to obtain the 3D conductivity structure. The electrical characteristics and structure framework of the 3D model were discussed by slices of the model with different depths and orientations. The results show that 2D/3D characteristics for the deep structure of the region are obvious. The model is proved to be high in precision by comparison between the observed data and the model response. Combined with the discussion of properties of the main geological body, the deep low resistivity anomaly between the high resistivity rock mass may be the reflection of altered rock or the ore body.关键词
