Ilona Posted June 9, 2016 Share Posted June 9, 2016 Hi there, I use GWB for for precipitation of carbonate minerals in a freshwater lake in which the Mg/Ca ratio changes according to the changes of water resource. I found three types of dolomite in the database: dolomite, dolomite-disordered, dolomite-ordered, but I do not really know what is the difference between dolomite and dolomite-ordered? Have somebody ideas? Or do you know where can I find the references of tha database? Thanks!!!! Ilona Quote Link to comment Share on other sites More sharing options...
katezat Posted June 9, 2016 Share Posted June 9, 2016 Hello Ilona, Most of the thermo datasets have a bibliography which you can find on the Header section in TEdit or at the end of the dataset if you view the file with a text editor. The GWB’s default thermodynamic dataset (thermo.tdat) was compiled at LLNL, but other thermo datasets also come installed with the software. The expanded LLNL dataset, thermo.com.V8R6+.tdat, specifies which references were used for many of the species and minerals. The log K values for dolomite, dolomite-ord, and dolomite-dis are pretty close in the two datasets, so it’s likely they’re referencing the same data. Hope this helps, Katelyn Aqueous Solutions LLC Quote Link to comment Share on other sites More sharing options...
