Abstract:

According to the related specification and requirements, analytical scheme and quality monitoring system for the analysis of 76 elements and 81 analysis parameters of crust rock and soil samples from the program of China Geochemical Baselines was designed based on the analytical system developed for the 76 elements geochemical mapping. The sophisticated noncontamination sample preparation procedure for rock samples was established, analytical technique with good accuracy was employed for analyzing major elements. The accuracy and precision was improved for major elements. It has been successfully applied in the China Geochemical Probe Program.

Key words: crust, element, analytical scheme, quality monitoring system
