Two new geochemical reference samples, basalt JB‐1b and coal fly ash JCFA‐1 have been prepared by the Geological Survey of Japan (GSJ) for collaborative studies on their chemical composition. Provisional values for twenty nine major, minor and trace elements are presented. The homogeneity tests showed that all elements studied can be considered to be homogeneously distributed. A description of their geological and mineralogical characteristics is also given.
