Abstract:
The magmatic water of granitoid related with gold deposits in. North China Platform is characterized by low
δD values (-120——85‰).The metamorphic water of ancient crystalline basement is also characterized by low
δD values (-95‰).The ore fluid of different types of gold deposits in China are characterized by multi-source and multi-origin, and the prominent feature is that the fluids are mixed with the meteoric water in various extent. Therefore, the
δD distribution of ore fluids of gold deposits in Eastern China manifests distinct latitude effect and coastal effect, and is in accorance with the contour of
δD values of Mesozoic meteoric water in China. The general metallogenic mechanism of gold deposits is that the ore-forming substances in source bed (rock) are remobilized and re-concentrated by the circulation of heated meteoric water.
