Wang et al_2025_Dataset_GCA

This is the first-version open-source dataset for the manuscript "Contrasting coprecipitation and recrystallization mechanisms for Ra immobilization via (Ba,Ra)SO4 solid solution formation in fractured crystalline rocks: Insights from 3D reactive transport modeling" submitted to GCA. The dataset of this version contains: 1) stoichiometric solubility products (Kst) for (Ba,Ra)SO4 solid solutions calculated for non-ideal and ideal mixing used in our reactive transport modeling (RTM); 2) the Python source code used to calculate the Kst values; 3) Kinetic rate constants for discrete (Ba,Ra)SO4 solid solutions for RTM; 4) the Python source code used to calculate stoichiometric supersaturation index (SSI).
