Abstract: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 ore-forming elements and media of the gold deposits of quartz vein-type and altered rock-type 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 calc-alkaline magma and its genesis belongs to magmatic hydrothermal type. In the two types of derived deposits, the meteoric water participated in their formation.
Key words: isotopic geochemistry gold deposit genesis North China Platform
