摘要
宣恩县埃山铅锌矿产于上寒武统土乐坪组碳酸盐岩中。高罗背斜轴部大断裂为区域导矿构造,背斜转折端断裂破碎带、层间破碎带为配矿构造,裂隙,尤其是顺层裂隙控矿。鲜红色、棕红色闪锌矿脉呈网脉状分布于破碎带中。成矿与燕山期伸展构造密切相关。高罗背斜铅锌矿化带与鄂西南最佳的Pb、Zn异常带相吻合,具有巨大的找矿潜力。
Aishan Lead-Zinc Deposit of Xuan＇en County is hosted in Leping Formation of the Upper Cambrian Carbonate Rock.Bright red,reddish brown sphalerite veins in stockwork are distributed in the broken belt.Mineralization is closely related to Mesozoic extensional tectonics.Lead-Zinc mineralized zone of Gaoluo anticline is in accordance with Pb,Zn anomaly zone.It has enormous potential for prospecting.
