Geochemical Modeling

Thermodynamics: The study of the relationships between temperature, pressure, and volume in systems, and how changes in one parameter affect the others.

Equilibrium chemistry: The study of the relationships between the concentrations of dissolved species in a system at equilibrium, and how to calculate these concentrations using thermodynamic data.

Acid-base chemistry: The study of how acids and bases react with each other, and how the pH of a solution is affected by the presence of acid or base.

Redox chemistry: The study of how electrons are transferred between different species in a system, and how this affects the concentration of different dissolved species.

Chemical kinetics: The study of how chemical reactions occur over time, and how the rate of these reactions can be affected by different factors such as temperature or pressure.

Environmental chemistry: The study of how chemical reactions occur and are affected by environmental factors such as temperature, pressure, and humidity.

Isotope geochemistry: The study of how isotopes of different elements are distributed in different geochemical systems, and how this distribution can provide information about the history of the system.

Mineralogy: The study of the physical and chemical properties of minerals, and how these properties are related to their formation and distribution in different geological systems.

Petrology: The study of how rocks are formed and how their composition can be used to infer information about the geological processes that formed them.

Geochemical cycles: The study of how different elements are cycled through different parts of the Earth system, and how this cycling affects the distribution and abundance of these elements in different parts of the Earth.

Reactive transport modeling: This type of geochemical modeling involves simulating the transport of dissolved solutes and reactions that occur between the solutes and the surrounding environment, such as groundwater or sediment.

Biogeochemical modeling: This type of modeling focuses on the biogeochemical cycling of essential elements, such as carbon, nitrogen, and oxygen, through biological and geochemical processes.

Geochemical reaction modeling: This type of modeling focuses on predicting the fate of individual or multiple substances in a system by simulating the chemical reactions that occur between them.

Equilibrium modeling: This type of modeling involves predicting chemical equilibrium between different substances in a system, based on their thermodynamic properties and conditions of temperature, pressure, and concentration.

Isotope geochemistry modeling: This type of modeling focuses on the isotopic signatures of elements and isotopes in geological materials, such as rocks, minerals, and fluids, to infer their origins, ages, and environmental conditions.

Geochemical speciation modeling: This type of modeling involves predicting the distribution of different chemical species of a solute in a system, based on its physicochemical properties and the surrounding environment.

Reactive surface modeling: This type of modeling involves simulating the reactions that occur between dissolved substances and the surfaces of minerals, rocks, and sediments in geological systems.

Geochemical cycling modeling: This type of modeling integrates different types of geochemical modeling to simulate the cycling of elements and nutrients through environmental systems, such as soils, oceans, and atmosphere.
