The whole concentrations of 19 constituents including major, minor and traceelements were determined for JLs-1 and JDo-1 samples issued from Geological Survey of Japan. The most remarkable feature of both samples is that they contain extremely low amounts of acid-insoluble residues. The relative enrichment of Ba and F compared with those of common carbonate rocks is also one of the specific feature of these samples.
