Qinling metallogenic belt

This area starts from Linxia and Zhouqu in Gansu in the west and ends in Ankang in Shaanxi in the east, with a total area of about 15× 104km2. The transportation is more convenient. In recent years, the mining economy in this area has developed rapidly, and lead-zinc mines in Fengtai, Xicheng and Xunyang have become national mineral bases.

The Qinling metallogenic belt is located in the eastern part of the central mountain system of Qin-Qi-Kun, and vertically crosses three blocks of North China, Qinling and Yangtze, and two plate suture zones of Shangdan (Wushan-Tianshui fault zone in Gannan) and Mianlue (Wenxian-Maqu fault zone in Gannan).

Three17 nonferrous metal deposits have been discovered in this area, including four large deposits 14, mainly including Fengtai ore field, Xi ore field, Zhenxun lead-zinc ore field, Ma Yuan lead-zinc mine and the newly discovered Daijiazhuang lead-zinc mine in recent years. The working area has excellent metallogenic conditions, and many deposits have been discovered, with1∶ 200,000 geochemical anomalies. The prospecting potential is huge.

This area is divided into 15 metallogenic prospect: Huangniupu-Beikuanping Caledonian-Yanshan Pb-Zn-Cu-Au-W-Mo metallogenic prospect, Fengxian-Taibai Hualixi-Yanshan Pb-Zn-Cu-Hg-Sb metallogenic prospect, Yang Shan-Zhashui Hualixi, Yanshan Pb-Zn-Cu-Fe-Ag metallogenic prospect, Zhen 'an-Xunyang Hualixi and Yanshan Pb-Zn-Au-Hg metallogenic prospect. Ningqiang-Zhenba Neoproterozoic-Mesozoic Pb-Zn metallogenic prospect, Bangou-Changba Pb-Zn polymetallic metallogenic prospect, Gansu Xialadi-Benshengou Pb-Zn-Ag metallogenic prospect, Gansu Liangdang northern Ag-Pb-Zn-Au metallogenic prospect, Gansu Diebu-Wudu Au-Pb-Zn-Cu metallogenic prospect, Gansu Huixian southern Pb-Zn-Cu polymetallic metallogenic prospect, Gansu Maqu southwest Au-Pb-Zn metallogenic prospect, Gansu Meiwu new temple.

Mainly lead and zinc, taking into account copper, gold and antimony. The main deposit type is sedimentary reformed lead-zinc deposit. Priority will be given to the exploration of lead-zinc deposits in Ma Yuan and Daijiazhuang, the exploration of tungsten-molybdenum polymetallic deposits in Xiaoliugou metallogenic area of Qilian metallogenic belt in the west extension of Qinling Mountains and the exploration of Jingtieshan lead-zinc mine.
