Geological characteristicsand analysis of the zinc-fluorite ore deposit prospecting in Naoyangping-Damogou mine at Pingli County, southeastern Shaanxi, China

The Naoyangping-Damogou zinc-fluoritemining area is located in the Caledonian fold belt of the east wing of Pingli Anticlinorium in the North Dabashan Mountains. The region is located within the Qinling fold belt, which was formed during intense activity in the late Paleozoic.The belt has a north-north-west orientation and consists of a system of anticlines, synclines, thrust faults, shear strike slip faults and ductile shear zone. Two dominant fault structures and other small faults sets appear closely associated with zinc-fluorite mineralization within the region, with several depositscommonly occurring along these faults.Based on analysis of geological background and geological characteristics of the zinc-fluorite mineralization in the region, the ore-controlling factors and the genesis of the zinc-fluorite ore deposit have indicated that the geological conditions for prospecting a large-scale deposit are existing in the Naoyangping-Damogou mining area. It also establish the metallogenic favorable locations prediction of the zinc-fluorite deposit in this area.
