A set of eight geochemical standard reference samples of stream sediments was prepared. The original purpose was to use these samples as primary standards for the data quality monitoring of a nation‐wide regional geochemical survey program in China.

Recommended values for over 50 trace and minor elements were derived by a method of repetitive elimination of outliers and calculation of central “tendency” from several central
