Geologic and thermodynamic characteristics of the Salton Sea geothermal system
Abstract
The area is in the San Andreas Rift Valley of southern California. The geothermal reservoir is in an arkosic sandstone more than 2,000 feet thick and below an insulating shale 2,000 to 3,000 feet deep. Interstitial concentrated NaCl-CaCl 2 -KCl brine occurs; no steam is present. At 3,000 feet, the temperature exceeds 300 degrees C and is 360 degrees C at 7,000 feet. Mineral reactions and alterations are described. Below the shale, the temperature-depth profiles approach adiabatic gradients. Thermal convection of the pore fluids is the primary mechanism of heat transfer. The temperature gradient is equated to salinity with changes in depth. Various other physical features are evaluated. The brine formed by the evaporation of Colorado River water trapped in the reservoir sands.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
