Highlights

The western tungsten deposit area of Zhen’an is located in the south Qinling tectonic belt.The main exposed strata in the area are Paleozoic carbonate rocks.The magmatic rocks are mainly rouge dams，lazy benches and Sihaiping granite bodies.The fault development in the area provides a ore-conducting and ore-bearing structure for the tungsten ore formation in the area.The skarn-type tungsten mineralization occurred in the near EW strike fracture zone.In addition，the NE-NNE-oriented quartz vein-type tungsten mineralization also developed，which together constitute the main tungsten-molybdenum mineralization type in this area.This paper mainly conducts field investigation and indoor research on typical tungsten deposits such as Qipangou and Hetaoping in the mining area，and has obtained the following knowledge：（1）The ore-controlling structure in the ore-concentrating area is a tectonic fracture in two different directions from the EW and the NE-NNE direction.（2）According to the tectonic background of the area，the tectonic fractures in the NE-NNE of the ore-concentrating area are formed by the Late Indosinian-Yanshanian tectonic activities，and the near-east tectonic fractures are mainly formed by the Indosinian tectonic activities.Compared with the Yanshanian tungsten-molybdenum ore-forming period，the near-east-west fault is a pre-mineral structure，while the NE-NNE fault fracture belongs to the metallogenic structure.（3）The type of tungsten mineralization in the ore-concentrating area is mainly composed of hydrothermal quartz vein type and fault-controlled skarn type.The quartz vein type is mainly controlled by the NE-NNE fault and joint fissures, and the skarn type is mainly controlled by the near-east-west fault fracture zone.
