Kinetics of Water-Rock Interaction [Hardcover]

Geochemical kinetics as a topic is now of importance to a wide range of geochemists in academia, industry, and government, and all geochemists need a rudimentary knowledge of the field. This book summarizes the fundamentals of geochemical kinetics with examples drawn especially from mineral dissolution and precipitation. It also encompasses discussion of high temperature processes and global geochemical cycle modeling. Analysis of textures of rocks, sediments, and mineral surfaces are incorporated throughout and provide a sub-theme of the book.

Systems at the surface of the Earth are continually responding to energy inputs - rived ultimately from radiation from the Sun or from the radiogenic heat in the - terior. These energy inputs drive plate movements and erosion, exposing metastable mineral phases at the Earths surface. In addition, these energy ?uxes are harvested and transformed by living organisms. As long as these processes persist, chemical disequilibrium at the Earths surface will be perpetuated. In addition, as human populations grow, the need to produce food, extract - ter, and extract energy resources increases. These processes continually contribute to chemical disequilibrium at the Earth surface. We therefore ?nd it necessary to predict how the surface regolith will change in response to anthropogenic processes as well as long-term climatic and tectonic forcings. To address these questions, we must understand the rates at which reactions occur and the chemical feedbacks that relate these reactions across extreme temporal and spatial scales. Scientists and - gineers who work on soil fertility, nuclear waste disposal, hydrocarbon production, and contaminant and CO sequestration are among the many researchers who need 2 to understand l#†
