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.

Oxygen budgets calculated fromin situ oxygen microprofiles for Northern Adriatic sediments

TL;DR: In this article, the authors used diffusion-reaction models to describe the oxygen profiles from both the shallow and the deep sediments from the Northern Adriatic Sea, and calculated budgets from in situ oxygen microprofiles, recorded with an oxygen profiling lander in 1992 and August 1993.

Density-driven groundwater flow near salt domes

TL;DR: In this article, the authors numerically modeled the possible dynamics of brine-density flow induced by solute concentration gradients; and thermal convection induced by temperature gradients, around hypothetical salt domes.

Geochemical controls on anaerobic organic matter decomposition in a northern peatland

TL;DR: In this article, in situ dissolved inorganic carbon (DIC) and methane (CH4) production rates from a beaver pond to a central bog dome and related them to organic matter properties, Gibbs free energies of respiration, and d13C values of DIC and CH4.

Soil-gas method for tracing neotectonic faults in clay basins: the Pisticci field (Southern Italy)

TL;DR: In this article, two soil gas surveys were performed in 1991 and 1993 over an area of 95 km 2 at Pisticci, Southern Italy, aimed at assessing the relationship between soil gas distribution and fracture systems in a Plio-Pleistocene clay basin located in the Bradanic trough.

Organic matter diagenesis in freshwater sediments: The alkalinity and total CO2 balance and methane production in the sediments of Lake Washington1,2

TL;DR: In this article, the interstitial water chemistry of Lake Washington sediments collected with an in situ sampler was studied, and a stoichiometric model was used to identify the increase of alkalinity with depth in the lake interstitial waters.
