陕西南郑县马元一带发现大型层控型铅锌矿带

A large-scale stratabound lead-zinc metallogenic belt discovered in the Mayuan area, Nanzheng County, Shaanxi Province

摘要: 在陕西省南郑县马元地区碑坝穹隆周缘的震旦系灯影组白云岩中发现了长大于60km、宽10～200m的铅锌成矿带。南矿化带长大于20km,宽20～120m,已圈出多条铅锌矿体;中矿化带长大于30km,宽20～200m,地表已发现多条铅锌矿体;北矿化带长大于10km,宽10～100m。主矿体长2560m,平均厚度8.60m,平均锌品位4.14%。初步认为该铅锌矿带属层控型,具有形成超大型矿床的前景。
