青海某地第三系红色碎屑岩层中金异常特征及成因探讨

A PRELIMINARY DISCUSSION ON THE CHARACTERISTICS AND GENESIS OF GOLD ANOMALIES WITHIN THE TERTIARY RED CLASTIC BEDS IN A CERTAIN AREA OF QINGHAI PROVINCE

对青海某地第三系红色碎屑岩层中的金异常特征进行了综述，指出金异常主要存在于第三系中段岩层中，异常在水系沉积物中强度最大，并认为金异常由次生富集作用形成。

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.
