摘要
系统地论述了华北地台南缘不同类型金矿床的硫、铅、氢、氧和碳同位素地球化学，指出它们一致表明石英脉型和蚀变断层岩型金矿床的成矿元素和介质主要来自太古代变质岩系，爆破角砾岩型金矿床的成矿元素和介质则来自燕山期钙碱系列岩浆。
The isotopic features of sulfur, lead, hydrogen, oxygen and carbon for different types of gold deposits in the southern margin of North China Platform were described in detail, which all unanimously indicated that the oreforming elements and media of the gold deposits of quartz veintype and altered rocktype derived from the Archean metamorphic series and their geneses belong to metamorphic hydrothermal type, and that of the deposits of explosive breccia type derived from the calcalkaline magma and its genesis belongs to magmatic hydrothermal type. In the two types of derived deposits, the meteoric water participated in their formation.
