TL;DR: In this paper, the origin and transport of spring waters from which travertines precipitate are elucidated by chemical and isotopic studies of the travertine and associated thermal springs and gas vents.

TL;DR: In this article, the chemical and isotopic composition of water and gas thermal discharges from six hydrothermal systems in the Tarapaca and Antofagasta regions (northern Chile): Surire, Puchuldiza-Tuja, Pampa Lirima and Torta de Tocorcupi, to determine the chemical-physical conditions at the fluid source.

TL;DR: In this article, the authors used the available dataset (bulk mineralogy of the reservoir, gas-cap composition and selected pre- and post-CO 2 injection water samples) provided by the International Energy Agency Weyburn CO 2 Monitoring & Storage Project (WEASP) to reconstruct the pre-injection reservoir chemical composition (including pH and the boundary conditions at 62°C and 15MPa).

TL;DR: In this article, the presence of three different phases during the Nyiragongo volcano's 2002 eruption is confirmed by new 238U and 232Th series radioactive disequilibria data, which show that the volcano is likely to change in the future, trending toward more common occurrence of flank eruptions.

TL;DR: In this paper, water and dissolved gases collected along vertical profiles in the five basins (main, Kabuno Bay, Kalehe, Ishungu, and Bukavu) forming the 485 m deep Lake Kivu (Democratic Republic of the Congo) were analyzed to provide a geochemical conceptual model of the several processes controlling lake chemistry.
