Abstract
The Yinmusi lead-zinc deposit belt in Fengxian County,Shaanxi Province is located in the middle section of the Fengtai mining area,from Bafangshan to Baguamiao to Yinmusi mining area.The ore body is located near the interface between the top of the Middle Devonian Gudaoling Formation and the bottom of the Upper Devonian Xinghongpu Formation in the north inverted wing of the Yinmusi anticline,and is flanked to the east along the Yinmusi anticline with a lateral angle of 20°～30°.It is controlled by interlayer faults in the NWW direction;The ore bearing rock types are silicified limestone and calcite quartz veins;There is a negative correlation between lead zinc ore and copper ore bodies,and the occurrence of sudden changes often forms rich and thick sac-shaped ore bodies.According to the ore-forming laws,there is a certain exploration space in the northern wing of the anticline,the upper part of the mineralized alteration,and NWW trending faults within the limestone.关键词
