| 摘 要： | 关门山层控铅锌矿赋存于长城系高于庄组五段条带状白云岩中。条带状白云岩属藻白云岩。在小西沟、关门山两工业矿段的条带状白云岩铅、锌含量明显高于其它地区。岩石碳、氧同位素表明,白云岩属正常海相白云岩,铅同位素以正常铅为主,模式年龄为1500—1800Ma,铅来源于基底岩石和壳下。条带状白云岩可以作为找矿的直接标志。

| Abstract: | Strata-bound lead-zinc ore deposit occured in striped dolomite of the fifth member in Gaoyuzhuang Formation Changcheng System in Guanmenshan. Striped dolomite is algae dolomite. Lead and zinc contents is higher evidently in striped dolomite of industrial ore-member in Xiaoxigou, Guanmenshan than other areas. Carbon and oxigen isotopes show that dolomite is normal marine one, lead isotope is mainly normal lead, model age 1 500-1 800Ma. Lead originate from basemental rocks and lower crust. Striped dolomite can be made indication of ore. |
