A Discussion on Mineralizaion Dynamics Mechanism of Gold Deposits on the Southern Edge of the North China Plate
华北陆块南缘金矿成矿动力学探讨

Unstable isotope analyses show that there is no relationship between gold deposits and granite in Xiaoqinling-Xiongershan area.This paper has studied the age and space relationship between the gold deposits and the granite as well as the formation dynamics of the gold deposits.The authors consider that it was the evolution of the Yanshanian granitic magma that caused the formation of the gold deposits.The ore elements-bearing fluids formed and evolved with the whole process of the granitic magma evolution.In this process,the granitic magma not only offered ore-bearing elements but also huge thermodynamic energy for mineralization.The Yanshanian detachment tectonic belt performed as the main regional ore-controlling and ore-hosting structure.A gold mineralization model,i.e.the Magmatic Thermodynamic Gold Mineralization Dynamics Mechanism is given in this paper,which is of great significance in gold deposit exploration.
