河南崔家庄铅矿区四岔口组下段地球化学特征及找矿意义

崔家庄铅矿区地处黑沟—栾川断裂带与瓦穴子—乔端断裂带之间,成矿地质条件较好.矿区1∶1万土壤化探剖面成果显示,宽坪群四岔口组下段主成矿元素Pb、Ag富集强烈,分布极不均匀,元素间相关性显著,成矿潜力大;单元素异常及综合异常均显示,异常与断裂构造关系密切;经异常查证及追索,目前发现3个铅矿体(伴生银、锌)及1个矿化点,丰...

Geochemical characteristics and the ore prospecting significance of Lower stage of Sichakou formation in Cuijiazhuang Pb deposit,Henan province

Cuijiazhuang Pb deposit is located between Heigou-Luanchuan fault belt and Waxuezi-Qiaoduan fault belt.Here took place active regional magmatism with advantageous metallogenic and geological background.Results of soil geochemical section at scale 1:10000 through the deposit area show that ore elements of Pb and Ag are strongly enriched,extremely and unevenly distributed in Lower stage of Sichakou formation of Kuanping group,correlation between the elements distinct and metallogeny potential.Both single element anomaly and integrated anomaly are closely related to fault.During the anomaly check and tracing 3 Pb ore bodies and 1 ore occurrence were discovered with the by-product of Ag and Zn.The discovery will provide more information and guidance for further prospecting of Pb-Zn-Ag deposits in Kuanping group in East Qinling mountain area.
