简论金的成矿时代

    THE OUTLINE OF METALLOGENIC EPOCH OF GOLD DEPOSITS

    • 摘要: 金矿床几乎形成于所有地质时代,但在不同时期其矿化强度明显有别.就全球而言,前寒武纪和新生代是金矿的重要成矿期.而我国金矿床的成矿时代则以燕山期为最重要,吕梁-晋宁期和海西期次之,其余为五台期和喜马拉雅期.金成矿作用具有周期性和继承性,内生成矿作用与外生成矿作用交替出现,每一个成矿期的特点在下一个成矿期部分重现.

       

      Abstract: 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.
