Trace element concentrations of the US Geological Survey's basalt standards (BCR2, BIR1a) and a granite standard (GSP2) were determined during five years from 2015 to 2019. These data will be helpful for judging data quality of trace element concentrations determined for the geochemical interpretation at KIGAM trace-isotope team. In addition, our data also include measurements of some elements whose recommendation values are not available in the US Geological Survey report.
