GSJ Reference Samples ?
The Geological Survey of Japan (GSJ) has issued 42 rock reference samples for the analysis of major, minor and trace elements, isotopic compositions and isotopic ages. The purpose of this standard reference material project in Geological Survey of Japan is to improve and check the reliability of analytical data obtained from different methods and different laboratories. Therefore, these samples (total number is over 8000) have been distributed to analytical laboratories in 43 countries worldwide and the analytical data obtained with cooperative works were compiled and used to improve the accuracy of the data
