摘要
陕西省凤县银母寺铅锌矿带位于凤太矿集区中段八方山-八卦庙-银母寺矿集小区,矿体赋存于银母寺背斜北倒转翼中泥盆统古道岭组顶部与上泥盆统星红铺组底部界面附近,随银母寺背斜向东侧伏,侧伏角20°~30°,沿NWW向层间断层控制;赋矿岩性为硅化灰岩、方解石石英脉;铅锌矿与铜矿体呈负相关,产状突变部位往往形成富且厚的囊状矿体。依据成矿规律背斜北翼翼部、矿化蚀变体上部、灰岩内NWW向断层等部位具有一定的找矿空间。
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.
