Data for: Temperature Controls on Carbonate Mineralization in Basalt–CO₂ Systems: The Role of Cation Partitioning

This dataset contains the numerical data underlying Tables 1–2 and Figures 1–7 of the manuscript, including initial fluid compositions, mineral assemblages, carbonate precipitation, secondary mineral precipitation, pH, pe, alkalinity, dissolved inorganic carbon, and cation sequestration efficiencies as a function of temperature for saline and aquifer systems.
