The Fushime geothermal area is located at the southeastern part of the Satsuma Peninsula, Kyushu, Japan. 

More recently, the concentration of Tc in coastal seawater samples collected 1993 in Fukuoka (Kyushu) Japan was determined by ICP-MS. Tc was enriched by coprecipitation on iron hydrated oxide and separated from impurities by solvent extraction and ion exchange techniques. The Tc concentrations found were only 1-7, uBql. The activity ratio of Tc/ - Cs was 2.7 10", which is very close to the value expected for fallout from nuclear tests [79].

Prototype maglevs have been built by Japan Railways and by Japan Air Lines, but the most interesting is a streamlined 72-foot, 17-ton test vehicle that operates regularly over a 4-mile track 30 miles north of Miyazaki, on Kyushu, Japan s southern island. Operated from a control room at one end of the roadbed—there is no engineer aboard—it carries forty-four passengers and can reach 260 miles per hour. (It was an unmanned version that hit the 321-mph world speed record in 1979.)

The coupled precipitation kinetics-fluid flow model was applied to the distribution of Si02 content and K2O content of the hydrothermally altered andesite in the Hishikari Au-Ag mine area, south Kyushu, Japan by Shikazono et al. (2002). This will be described in section 1.4.6. 

BNL, Halliburton Energy Services, and Unocal Corp. have developed cements suitable for geothermal wells with this formulation [11]. The brand name of this cement is ThermaLock. This cement was tested successfully in Unocal s geothermal well in Sumatra, Indonesia, and its first use has been reported by Japan Petroleum Exploration Company for completion of geothermal wells in Kyushu, Japan. 

Figure 9. Plots of Li and radiogenic isotopes for mantle rocks, (a) 5 Li vs. Sr/ Sr (b) 5 Li vs. Nd/ Nd (c) "Sr/ Sr vs. Pb/ Pb (d) 5"Li vs. Pb/ Pb (Nishio et al. 2003, 2004). Symbols + = south Pacific island basalts (six islands) O = Iherzolite xenolith, Bullenmerri, Australia = Iherzolite xenolith, Sikhote-Alin, Russia (three localities) A = dunite-peridotite-pyroxenite xenolith, Kyushu, Japan (two localities) V = Iherzolite xenolith, Ichinomegata, Japan. The ocean island data are from bulk rocks, the xenolith data are clinopyroxene separates. For explanations of the derivation of radiogenic isotope fields (DM, EMI, EM2, HIMU), see Zindler and Hart (1986). The estimate for Li isotopes in DM is based on MORE. The Li isotopic ranges for the other mantle reservoirs are based on Nishio et al. (2004) and Nishio et al. (2003), but these will require further examination (hence the use of question marks).
