Rare earth elements (REEs) in twelve standard rock samples have been determined by inductively coupled plasma atomic emission spectrometry after separation of diverse metal ions with cation exchange resin. These rock samples are old six standard rocks (W-1, BCR-1, AGV-1, GSP-1, JB-1, JG-1) and new six standard rocks (JB-2, JB-3, JA-1, JR-1, JR-2, JGb-1) issued from the Geological Survey of Japan. These samples are various types of igneous rocks, which show various shapes of the REE distribution patterns. Geochemical characteristics of these standard rock samples will be discussed from the relationships between rock types and the shapes of the REE pattern.
