TLDR
The approach of this book to geochemistry can be summarized in the question: What happens, and how fast does it happen, when waters, solids, and gases interact in the earth's surface environment? The environment of the earths surface is made of solids and fluids, and the interactions among them are responsible for much of what is taking place in the physical world around us as mentioned in this paper.
Abstract
The approach of this book to geochemistry can be summarized in the question: What happens, and how fast does it happen, when waters, solids, and gases interact in the earths surface environment? The environment of the earths surface is made of solids and fluids, and theinteractions among them are responsible for much of what is taking place in the physical world around us. The dissolved load of natural waters and the materials of which sediments are made are the products of reactions taking place practically everywhere on land, in the atmosphere, and in the hydrosphere. Thus the term water and sediment environments applies effectivelly to much of the surface environment of the earth, including the zone of up to a few kilometers above and below the land and ocean surface. Evolution present itself to us as a more or less complex variety of processes-geological, physical, chemical, and biological. To this end, the inclusive title Geochemical Processes was chosen for the book, to introduce a text that emphasizes processes and time-dependent phenomena.

Modeling pre-industrial C-N-P-S biogeochemical cycling in the land-coastal margin system

TL;DR: In this article, the role of the land-coastal margin system in global climate forcing and to assess changes in element cycling in response to natural and anthropogenic forcings is examined.

Chapter 4 Thermodynamic Control on Terminal Electron Transfer and Methanogenesis

TL;DR: In this article, a model analysis for peat-sand mixtures suggests that acetoclastic methanogenesis can be inhibited by CH4 and dissolved inorganic carbon (DIC) accumulation, which was identified by inverse modeling near 25 kJ mol-1.

Stable Isotopes in the Sedimentary Record

TL;DR: In this paper, the interpretation of the sedimentary records of several common stable isotopes and their fractionation in natural systems is addressed, including the isotopes of hydrogen (D/H) and oxygen (18 O/16 O) that occur in the global water cycle and are fractionated by a number of physical and chemical processes in the gas-liquid-solid H 2 O system.
