THE METALLOGENIC EPOCH OF GOLD DEPOSITS IN CHINA

The mineralizing ages of some typical gold deposits were discussed in Jiapigou,Liaoning, Eastern Hebei Zhangjiakou,Xiaoqinling,Jiaodong,Western Hunan,Western Guangdong-Hainan, Western Yunnan, Northern Xinjiang and Taiwan gold ore concentrated fields and so on. On the basis of this,the features of distributions,types and genesis of gold deopsits at various geologic periods were summarized. During the evolutionory history of gold mineralization,Late-Archeozoic or Early-Proterozoic Era and Mesozoic-Cenozoic Era are the two most important periods,the former is characterized by the greenstone formation type of gold deposits, but the latter is characterized by granite formation type of gold deposits. The most striking features of gold deposits in China are older ages of source of metallogenic material and younger fixed ages of deposits, that is, gold mineralization shows the distinct inherirance.
