【摘要】 唐家铅锌矿床赋矿层位是上震旦统灯影组，矿体受构造控制．根据同位素地球化学研究，矿石中硫主要来自围岩地层，成矿介质以循环地下热卤水为主．成矿模式年龄小于赋矿层位年龄．是一典型的沉机－热液改造型铅锌矿床．更多还原

【Abstract】 Tangjia Pb-Zn deposit is hosted by dolomitite of the Dengying Formation of the Upper Sinian. The orebodies are controlled by fractures.Research on isotope geochemistry indicates that sulfur of sulfides from the ores was derived mainly from the host stratum and that ore fluid was a hot brine.Pbisotope model age is less than age of the host stratum.It is a typical sedimentury-reformation deposit.更多还原
