Abstract凤太矿集区位于秦岭泥盆系铅锌等多金属成矿带的中段,铅锌矿床主要产于中泥盆统古道岭组和上泥 盆统星红铺组之间的硅质岩中。对区内三个典型铅锌矿床中s、Pb同位素组成研究表明,铅硐山、八方山、银 母寺3个铅锌矿床金属硫化物的d34S值变化范围较小,均不超过10‰。区内硫化物的d34S值总体变化于4.3‰ ~13.2%。,指示s主要来自海水硫酸盐的还原作用。3个矿床矿石矿物的Pb同位素中2”Pb/2“Pb变化于17.775 ~18.180,2”Pb/2”Pb变化于15.457~15.805,2”Pb/2“Pb变化于37.977~38.670。各个矿床之间Pb同位素组成 均有较大的重叠,暗示3个铅锌矿床具有相似的铅源。通过Pb同位素构造模式图解以及△口△y分类图解分析 表明,矿石铅来源于早古生代中期到末期扬子板块向华北板块之下俯冲以及晚古生代扬子板块、秦岭微板块向 华北板块俯冲的历程中。zh_CN
