Comprehensive information prospecting model for Yishengdian volcanic rock type uranium polymetallic deposit in Duolun County,Inner Mongolia
[Objective]The Yishengdian uranium polymetallic deposit(mineralization)is located in the Late Jurassic Manketou Obo subvolcanic rock mass near the Xigangou volcanic mechanism,mainly controlled by the combination of NW-NNW trending fault structures and the hidden explosive breccia belt within the subrhyolite rock mass.The study and establishment of a comprehensive information exploration model for this deposit is of great significance in guiding the exploration of mineralization zones.[Methods]On the basis of studying the geological conditions,ore-forming bodies,ore-forming structures and structural planes,and ore-forming process characteristics of uranium mineralization in the region,this article conducted a systematic and comprehensive research work by combining the soil geochemical characteristics of the mining area with information on induced polarization,gamma energy spectrum,activated carbon,and electrostatic alpha anomalies.[Results]A geological exploration model for the mining area was established through research,and the main physical and chemical exploration indicators for mineralization in the mining area were summarized and summarized,including volcanic structure control,soil geochemical anomaly areas,low resistivity high polarization body anomalies,and geometric shape anomalies formed by deep penetrating radioactivity.A comprehensive information exploration model of geology geochemistry geophysics"trinity"was constructed for the mining area.[Conclusions]The study suggests that there is potential for the formation of medium to large uranium polymetallic deposits in the overlapping areas of fault fracture zones,subvolcanic rock contact zones,and cryptoexplosive breccia structures in the Yishengdian mining area,where geochemical and geophysical anomalies coincide.New breakthroughs have been made in using models to guide mineral exploration.
