THE OUTLINE OF METALLOGENIC EPOCH OF GOLD DEPOSITS

The metallizing processes of gold takes place in almost every geologic eras. Among them the Precambrian and Cenozoic eras are the main metallogenic epoches in the world. In China, the Yanshanian is the most important period of metallizing process of gold, followed by the Variscan, Luliang-Jinningian, Wutainian and the Himalayan periods. The gold metallization is periodical and inheritable, that is,the endogenous and exogeneous metallizing processes occur alternately, and the metallogenic features partly repeat in next metallizing period.
