| Abstract: | Over geological time scales,Earth degassing has a significant impact on atmospheric carbon dioxide(CO2) concentrations,which are an important component of global carbon cycle models.In Tibet,structural conditions and associated widespread geothermal systems lead to carbon dioxide degassing during geothermal water migration.We characterized the hydrochemical conditions of two geothermal fields on the Tibetan Plateau.The chemical composition of geothermal waters was controlled by K-feldspar and albite.Geother... |
