| 英文摘要: |
| According to the metallogenic process and occurrence, the placer gold deposits in China could be divided into 12 types and brief descriptions about the mineralization features and economic perspective for each placer gold type is made in the paper. A great deal of exampies are provided to summarize the ore-forming conditions, geological settings, and enrichment regularities of the gold placer deposits in China. It is concluded that the metallogeny of placer gold in China is characterized by multi-source and multi-stage enrichment. Geomorphic abnormal zones and flood alluviation are believed to have played an important role to the forming of placer gold deposits. On the basis of this study, x placer gold areas and 33 placer gold prospects are outlined and their potential reserves predicted respectively. |
