The Research On The Geological And Geophysical Prospecting In Jindouzishan Lead Zinc Ore, Taipusi Banner, Inner Monggol Autonomous Region

The Jindouzi ores are a lead, zinc and Argentine metallic bed. The deposit are located at the north edge of Huabei Uplift, Baiyunerbo rift valley belt.The paper analysizes the geological features and geophysical characteristics of the Jindouzai deposit, takes studies on the genesis of ore deposit and ore-controlling factors, makes a forecast of the prospecting potential for the mining area, puts forward three prospecting areas, and provides a theoretical basis for the next phase of exploration.The large area of granite exposed in this area id the early Yanshan granite, and the exposed stratain the region are mainly the Bayan Obo group Mesoproterozoic (Pt2B), the output of the rock body is not selective, the most important ore-controlling structure is the north-east of the F1 fault, the genesis of ore deposits belongs to epithermal deposits, the wall-rock alteration closely related to lead-zinc mainly includes silicification, sericite and carbonate content of Mn, the ore body has the characteristics of low resistivity and high polartization, the dual-frequeency IP method can well reflect the mineralization information, body positioning in this mining area.The deposits have been found by the four major ore belt, including 12 bodies, of which No.I body in No.Iore belt is the main ore body. No.I body is towards northwest strike 57°, up to 600 meters, the largest extension isf more than 492 meters deep, with an average thickness of 5 meters, and the other ore body is small-scale.Through analysizing and research on the metallogenic background, genesis of ore deposit, ore-controlling factors and metallogenic rules, the Jindouzi mining area has a good prospecting. Especially in the south of the mining area, three northeast lead-zinc faults and several broken limonite alteration zone in this area are the most important area of prospecting.
