Water chemistry data from: Fournier, R.O., Thompson, J.M. and Austin, C.F., 1980. Interpretation of chemical analyses of waters collected from two geothermal wells at Coso, California. Journal of Geophysical Research: Solid Earth, 85.B5, pp.2405-2410, https://doi.org/10.1029/JB085iB05p02405. Water chemistry data was digitized for 13 samples. Reported attributes include: Sample name, Sample ID, Type, Collection date, Collection time, State, Latitude, Longitude, Location resolution, Location error, Collection depth, Temperature, pH (field), pH (lab), Boron (B), Barium (Ba), Calcium (Ca), Chloride (Cl), Carbonate (CO3), Cesium (Cs), Fluoride (F), Bicarbonate (HCO3), Potassium (K), Lithium (Li), Magnesium (Mg), Sodium (Na), Ammonium (NH4), Rubidium (Rb), Silica (SiO2), Sulfate (SO4), Strontium (Sr), Reported cations, Reported anions, Cations, Anions, Reported total dissolved solids, Salinity, Charge balance, Isotopic composition of oxygen in water (Delta 18O H2O), Isotopic composition of oxygen in sulfate (Delta 18O SO4), Author comment. Data was digitized from Table 1 of 1. The following data was not digitized: Table 1 (partial): atomic ratios of major elements, estimated aquifer temperatures.
