| Abstract: | This paper sums up characteristics of Au anomalies within Tertiary red clastic beds in a certain area of Qinghai Province,and points out that Au anomalies mainly exist in the middle part of the Tertiary strata, that anomalies are most strong in stream sediments, and that Au anomalies result from secondary enrichment of Au. |
| Keywords: | gold anomaly genesis Tertiary clastic rock Qinghai |
