Geochemical Modeling of Reaction Paths and Geochemical Reaction Networks

Reviews in Mineralogy and Geochemistry, 2009
From the discussions in previous chapters, we can see that in order to understand the kinetics of dissolution and precipitation reactions, we really need to understand geochemical reaction networks. The previous chapters have depicted a complex picture of the details of chemical reactions and kinetics.

Geochemical Modeling of Fracture Filling

Proceedings of SPE/DOE Improved Oil Recovery Symposium, 2002
Abstract This paper reports on a mathematical model to simulate hydrodynamics and fluid-mineral reactions in the fracture within a permeable media. Fluid convection, diffusion and precipitation / dissolution (PD) reaction inside a finite space are solved as a simplified representation of natural fracture mineralization.

Modeling the Geochemical Carbon Cycle

Scientific American, 1989
The authors have modeled the slow, long-term cycle in which geochemical processes transfer carbon among land, sea, and atmosphere. The model suggests that the earth may have been warmed in the past when buildups of atmospheric carbon dioxide enhanced the greenhouse effect.

Geochemical modeling of glass alteration

2023
Modeling the alteration of radioactive waste confinement glasses presents three main challenges: i) Chemical complexity: The numerous major chemical elements in the glass, fluid, and environmental minerals interact with each other through fluid and gas.

Modeling Geochemical Self Organization

1987
Rocks of a wide variety of origins can manifest symmetry breaking instabilities and the development of repetitive and other patterns of mineralization. Models are set forth that couple local processes (aqueous reactions, precipitation/dissolution and nucleation of mineral grains) to a variety of transport processes.

Environmental Applications of Geochemical Modeling

2002
Geochemical modeling is a powerful tool for characterizing environmental site contaminations and predicting environmental impacts. This book discusses the application of geochemical models to environmental practice and studies, through the use of numerous case studies of real-world environmental problems, such as acid mine drainage, pit lake chemistry,

Basic Concepts in Geochemical Modelling

1986
During this Nato-Advanced Course devoted to the Role of Air-Sea Exchange in Geochemical Cycling, basic concepts like steady-state, residence time and response time, stability or instability of the system, were often evoked by several speakers. It was therefore important that the participants became rapidly acquainted with these concepts.

Modelling of Geochemical Tracers in the Ocean

1990
The basic mechanisms of marine biology and chemistry which influence the atmospheric concentration of carbon dioxide are embedded in the three-dimensional current field of an OGCM. The modelled tracers are phosphate, alkalinity, oxygen, dissolved inorganic carbon, particulate organic carbon, and calcite, the latter three in three isotopes.

Geochemical and Biogeochemical Reaction Modeling

2007
This book provides a comprehensive overview of reaction processes in the Earth's crust and on its surface, both in the laboratory and in the field. A clear exposition of the underlying equations and calculation techniques is balanced by a large number of fully worked examples.
