Cioni R., Fanelli G., Guidi M., Kinyariro J., Marini L. Lake Bogoria hot springs (Kenya): geochemical features and geothermal implications. In: Journal of Volcanology and Geothermal Research, vol. 50 pp. 231 - 246. Elsevier, 1992.
Many boiling springs and fumaroles are present along the shores of Lake Bogoria, wich is a closed-basin alkaline saline lake typical of African Rifts. Two different geothermal waters, both of Na-HCO3 type have been recognized. The first, dicharged by the boiling spring located along the western shores of the lake, comes from a shallow steam-heated thermal aquifer. Its temperature is close at 100C, as indicated by chalcedony solubily, while the chloride content of these waters is slightly higher than 200 mgL-1. The second, recognizabled in the southermost boiling springs, is representative of a deeper and hotter geothermal reservoir. The occurence of mixing and boiling processe complicate the interpretation of geochemical data. Nevertheless, a chloride content of about 660mgL-1, an equilibrium tempearture close to 170C and the carbon dioxide partial pressure, at least 10-20 bar, have been estimated for geothermal deep reservoir
