Abstract
Nine new rock reference samples of the “Sedimentary rock series”, Chert JCh‐1, Dolomite JDo‐1, Lake sediment JLk‐1, Limestone JLs‐1, Stream sediments JSd‐1 to JSd‐3, and Slates JS1‐1 and JSl‐2 have been prepared by the Geological Survey of Japan(GSJ). Thirty major, minor and trace elements were determined using atomic absorption spectrometry, flame emission spectrometry, infrared absorption spectrometry and wet chemical techniques. The results of homogeneity tests showed that almost all elements, with a few exceptions, are considered to be distributed homogeneously in each reference sample.
