| 摘 要： | 金厂峪金矿是我国大型金矿床之一。矿床位于华北台地北缘附近的中生代强烈构造—岩浆活化区,金矿体产于叠加在韧性剪切带之上的脆性断裂和构造片岩的片理之中。金矿体的产状与韧性剪切带不一致;金矿与韧性剪切带形成之间有大的地质间断,表现为大时差和有构造岩浆活动。金品位与韧性剪切变形的强度不相关。这些表明金矿属后韧性剪切带型金矿床(刘连登,1987,1990,1991)。金矿与中生代花岗岩具紧密的时空联系和地球化学关联性,属岩浆热液成因。

| Abstract: | Jinchangyu gold deposit, located in the Qianxi county, Hebei province, is one of the largest gold deposit in China, The deposit occurs in the Mesozoic tectonomagmatic remobilized area at the north edge of North China Platform. The orebodies are hosted brittle faults overprinting on the ductile shearing zone in a tectonoschist belt. The occurrence of orebodies differs from the ductile shearing zone in that there is a great geological interval and a log time span between them. The deformation degree of ductile shearing does not correlate with gold grade (r = -0. 102). Au these facts indicate that Jinchangyu gold deposit belongs to postductile-shearing gold deposit defined by Liu Liandeng (1987, 1990, 1991). The deposit is closly related with the Mesozoic intrusion in spacial, themporal and geochemical, which manipest that it should belong to the tpye of magmatic hydrothermal. |
