Three new rock reference samples, Rhyolite JR‐3, Gabbro JGb‐2 and Hornblendite JH‐1 have been prepared by the Geological Survey of Japan for collaborative studies on their chemical composition. Twenty‐eight major, minor and trace elements were determined and presented. The results of homogeneity tests showed that all elements are considered to be distributed homogeneously in each reference sample. Geological and mineralogical characteristics are also described.
