Chemical compositions of serpentinization-generated hyperalkaline and associated fluids from the Samail ophiolite in Oman

This dataset contains temperature, pH, conductivity, water isotope, and aqueous compositions of circumneutral to hyperalkaline fluids sampled from the Samail ophiolite in Oman. Also included in this dataset are charge imbalance, ionic strength, mixing extent, and mineral saturation index calculated using the full aqueous chemical data.
