Thermoddem: A geochemical database focused on low temperature water/rock interactions and waste materials

摘要: The development of Thermoddem, a thermodynamic database devoted to geochemical modelling for environmental studies in general and, more specifically, chemical systems involving waste materials, is discussed here. Concerns are also focused on taking into account some specific needs modellers by proposing different output formats and important information concerning the solid phases, transformation path, paragenesis insights crystallographic details. This additional aims avoid considering phases that may not be "active" under current conditions. especially applications, ranging from material management pollutant behaviour, including context deep underground disposal. Selection rules conventions illustrated through example Fe-water system, while second details relationships between low high ionic strength media, point view databases. Technical aspects system Thermoddem its availability web (http://thermoddem.brgm.fr) provided.
