Geochemical Modeling of the Madison Aquifer in Parts of Montana, Wyoming, and South Dakota
TL;DR: In this article, stable isotope data for dissolved carbonate, sulfate, and sulfide were combined with water compo- sition data to construct geochemical reaction models along eight flow paths in the Madison aquifer in parts of Wyoming, Montana, and South Dakota.
Journal ArticleDOI
Oxygen and sulfur isotope systematics of sulfate produced by bacterial and abiotic oxidation of pyrite
TL;DR: In this paper, a series of pyrite oxidation experiments in the laboratory were conducted under aerobic conditions by using O2 as an oxidizing agent and under anaerobic conditions using dissolved Fe(III)aq as oxidant with varying δ18OH2O values in the presence and absence of acidithiobacillus ferrooxidans.
ReportDOI
An interactive code (NETPATH) for modeling NET geochemical reactions along a flow PATH
TL;DR: In this paper, the authors propose a method to solve the problem of homonymity in homonym identification, i.e., homonymization, in the context of homology.
Journal ArticleDOI
Chemical dynamics of the “St. Lawrence” riverine system: δDH2O, δ18OH2O, δ13CDIC, δ34Ssulfate, and dissolved 87Sr/86Sr
TL;DR: In this article, chemical and stable isotope analyses of the St Clair, Detroit, Niagara, and St Lawrence rivers (St Lawrence system) and their tributaries show that the chemical and isotopic compositions of the waters are strongly controlled by the geology of their drainage basins.
Journal ArticleDOI
Development of reaction models for ground-water systems
TL;DR: In this paper, the roles of thermodynamic speciation programs, mass balance calculations, and reaction-path simulations in developing and testing reaction models are contrasted, and an example is given testing multiple reaction hypotheses along a flow path in the Floridan aquifer where several reaction models were eliminated.

Sedimentary pyrite formation
TL;DR: In this paper, the major stages of formation (bacterial sulfate reduction, formation of Fe monosulfides by reaction of H 2 S with Fe minerals, pyrite formation, reaction of Fe mono-sulfides with elemental sulfur), limiting factors, coastal sediments of central Connecticut
Journal ArticleDOI
Calculation of Equilibrium Constants for Isotopic Exchange Reactions
TL;DR: In this article, it was pointed out that the possibility of chemical separation of isotopes is a quantum effect and that the difference in the free energies of two isotopic molecules can be directly calculated.
