Title: Solute geochemistry of the Snake River plain regional aquifer system, Idaho and eastern Oregon

Book ·
OSTI ID:6390589

The authors report that proposed geochemical reactions controlling solutes in the Snake River plain aquifer system are precipitation of calcite and silica; dissolution of olivine, pyroxene, pyrite, and and-hydrite; and weathering of plagioclase. About 20 percent of solutes are from aquifer framework weathering. The remainig solutes are from tributary drainage basins. Proposed geochemical reactions in the geothermal system are dissolution of fluorite, anhydrite, calcite, and feldspars; oxidation of pyrite; and ion exchange. Geothermal water residence time is about 17,700 years.
