| Abstract: | The gold resources show a great potential on the northern margin of North China platform. An investigation on the trace gold and S & P_b isotopes indicate that the metallogenesis of gold has a notable inheritance. The auriferous regional potential is a main prerequisite for forming the concentration of gold. The formation of granitic intrusions and ductile shear belts is a process for moblization of gold in the source beds. It is hard to form auriferous fluid for the normal magmatic crystallization diffferentiation. The second metallogenesis carried out by the second moblizing exhibits the main ore-forming mechanism of the endogenic gold deposits. A unique gold deposit system consists of a set of gold deposits related genetically to the Archaean greenstone and phanerozoic granitic rock in the platform. |
