- C. Liu, Yunchao Lang, H. Satake, J. Wu, Si-liang Li
- Environmental Science
- 1 August 2008
Because of active exchange between surface and groundwater of a karstic hydrological system, the groundwater of Guiyang, the capital city of Guizhou Province, southwest China, has been seriously… Expand
Geochemical provenance and spatial distribution of fluoride in groundwater of Mayo Tsanaga River Basin, Far North Region, Cameroon: implications for incidence of fluorosis and optimal consumption dose
- W. Fantong, H. Satake, +8 authors J. Zhang
- Geology, Medicine
- Environmental geochemistry and health
- 1 April 2010
The 500,000 inhabitants of Mayo Tsanaga River Basin are vulnerable to a “silent” fluorosis from groundwater consumption. For the first time, the groundwater is investigated for the purpose of… Expand
Origin of Hydrogen and Carbon Dioxide in Fault Gases and Its Relation to Fault Activity
- R. Sugisaki, Masahiko Ido, +5 authors Y. Mizutani
- Geology
- The Journal of Geology
- 1 May 1983
Gases occluded in fracture zones of active faults are characterized by a high concentration of $$H_{2}$$ and/or $$CO_{2}$$. A predominant gas species-$$H_{2}$$ or $$CO_{2}$$-is related to the… Expand
Evolution of CO2 in Lakes Monoun and Nyos, Cameroon, before and during controlled degassing
- M. Kusakabe, T. Ohba, +5 authors G. Kling
- Geology
- 1 February 2008
Evolution of CO2 in Lakes Monoun and Nyos (Cameroon) before and during controlled degassing is described using results of regular monitoring obtained during the last 21 years. The CO2(aq) profiles… Expand
Hydrogen and oxygen isotopic ratios and major element chemistry of Japanese thermal water systems
- O. Matsubaya, H. Sakai, I. Kusachi, H. Satake
- Geology
