Identification of Anthropogenic and Natural Inputs of Sulfate and Chloride into the Karstic Ground Water of Guiyang, SW China: Combined δ37Cl and δ34S Approach
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 seriouslyExpand

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
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 ofExpand

Origin of Hydrogen and Carbon Dioxide in Fault Gases and Its Relation to Fault Activity
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 theExpand

Hydrogen and oxygen isotopic ratios and major element chemistry of Japanese thermal water systems
More than 140 thermal waters of Japan were studied isotopically and chemically. Highly saline brines at Arima and Takarazuka, Hyogo-Ken, and Ishibotoke near Osaka indicate wide ranges of δ18O and δDExpand
