| 摘 要： | 本文从冀北地区脉状金矿床地质背景出发，系统研究了太古宇及与金矿化有关的岩体铅同位素特征，认为本区脉状金矿床成矿物质来自古老地壳及地幔。文中强调无论是产于变质岩中的金矿，还是产于花岗岩、碱性岩、超基性岩中的金矿，均受深大断裂及古隆起活化带控制。文中还分析了冀东、冀西北金矿床铅同位素区域性差异及产生原因。

| Abstract: | From geological background of vein- type gold deposits in northern Hebei and based on systematical study of Pb- isotopic character of rock masses of Archean related-with gold mineralization, the writers consider that the ore materials of vein-type gold deposits in this area come from ancient crust or mantle. It is emphasized in this paper that the gold deposits yielded in metamorphic rocks or in granite,alkaline rock and ultramafic rock are all controlled by deep fault and mobilized zone in ancient doming. The regional difference of Pb -isotopes oi gold deposits in eastern and northwestern Hebei and their genesis and are discussed in this paper. |
