Description: R interface to the PHREEQC program. PHREEQC is a geochemical
|
|
modeling program developed by the US Geological Survey that is designed to
|
|
perform a wide variety of low-temperature aqueous geochemical calculations.
|
|
PHREEQC is based on an ion-association aqueous model and has capabilities
|
|
for (1) speciation and saturation-index calculations; (2) batch-reaction
|
|
and one-dimensional (1D) transport calculations involving reversible
|
|
reactions, which include aqueous, mineral, gas, solid-solution,
|
|
surface-complexation, and ion-exchange equilibria, and irreversible
|
|
reactions, which include specified mole transfers of reactants, kinetically
|
|
controlled reactions, mixing of solutions, and temperature changes; and (3)
|
|
inverse modeling, which finds sets of mineral and gas mole transfers that
|
|
account for differences in composition between waters, within specified
|
|
compositional uncertainty limits.
