Geochemical Reference Samples Database from the Geological Society of Japan

[Adapted from the Geological Survey of Japan Sample Reference Standards Abstracts Page, 'aist.go.jp/RIODB/geostand/gsj1maine.html'] The Geological Survey of Japan (GSJ) has issued 31 rock reference samples for the analysis of major, minor and trace elements, isotopic compositions and isotopic ages. The purpose of this standard reference material project in Geological Survey of Japan is to improve and check the reliability of analytical data obtained from different methods and different laboratories.

Therefore, these samples (total number is over 8000) have been distributed to analytical laboratories in 43 countries worldwide and the analytical data obtained with cooperative works were compiled and used to improve the accuracy of the data. The following are samples that are available: Igneous rocks JA-1 Andesite (1982) Hakone volcano JA-2 Andesite (1985) Goshikidai sanukitoid JA-3 Andesite (1986) Asama volcano JB-1 Basalt (1968) Kitamatsuura basalt JB-1a Basalt (1984) Replacement sample of JB-1 JB-1b Basalt (1996) Replacement sample of JB-1 and JB-1a JB-2 Basalt (1982) Oshima volcano JB-3 Basalt (1983) Fuji volcano JF-1 Feldspar (1985) Ohira feldspar JF-2 Feldspar (1986) Kurosaka feldspar JG-1 Granodiorite (1967) Sori granodiorite JG-1a Granodiorite (1984) Replacement sample of JG-1 JG-2 Granite (1985) Naegi granite JG-3 Granodiorite (1986) Mitoya granodiorite JGb-1 Gabbro(1983) Utsushigatake JGb-2 Gabbro (1991) Tsukuba-san leucogabbro JH-1 Hornblendite (1992) Nishi-Dohira pyroxene hornblendite JP-1 Peridotite (1984) Horoman peridotite JR-1 Rhyolite (1982) Wada Toge obsidian JR-2 Rhyolite (1983) Wada Toge obsidian JR-3 Rhyolite (1990) Ashizuri peralkaline rhyolite JSy-1 Syenite (1993) Nephton, Ontario, Canada Sedimentary rocks JLs-1 Limestone (1987) Garo limestone JCp-1 Coral(1999) Ishigaki Island JDo-1 Dolomite (1987) Kuzuu dolomite JSl-1 Slate (1988) Toyoma clay slate JSl-2 Slate (1989) Toyoma clay slate JCh-1 Chert (1989) Ashio chert Sediments JLk-1 Lake sediment (1987) Lake Biwa JSd-1 Stream sediment (1988) Northern region, Ibaraki JSd-2 Stream sediment (1989) Eastern region, Ibaraki JSd-3 Stream sediment (1989) Central region, Ibaraki JMS-1 Marine sediment (1999) Tokyo Bay JMS-2 Marine sediment (2000) South Pacific Coal fly ash, Soil JCFA-1 Coal fly ash (1995) Isogo, Yokohama, Kanagawa JSO-1 Soil(1997) Machida, Tokyo JSO-2 Soil(1998) Tsukuba, Ibaraki Ore JMn-1 Manganese Nodule(1994) Southern Central Pacific Basin
