Report (1973–1984) on Two ANRT Geochemical Reference Samples: Granite GS-N and Potash Feldspar FK-N

Granite GS-N and Potash Feldspar FK-N are two ANRT reference samples prepared in 1973 in 960 and 567 kg, respectively. All data reported since 1973 are compiled in this report. GS-N and FK-N are now well characterized for major and minor elements. As for trace elements, working values have been assigned for 36 elements in GS-N and for 30 elements in FK-N. We need much more data on trace elements for characterizing them better. As GS-N and FK-N are still available in large quantities and are certain to remain so for two or three decades to come, a plea is made for contribution of more data on trace elements.
