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.

Support for an anaerobic sulfur cycle in two Canadian peatland soils

TL;DR: In this paper, sulfate was cycled between oxidized and reduced pools, likely stemming from TRIS or organic sulfur in the peat, indicating anaerobic S cycling can maintain BSR and contribute to low methane production in soils of ombrotrophic bogs.

Methane emission from hypersaline microbial mats: Lack of aerobic methane oxidation activity

TL;DR: Experiments indicate that hypersaiine microbial mats contain no aerobic CH4 oxidation activity, and probably no methanotrophic bacteria, although both O2 and CH4 are available.

Modelling the sulfide-oxygen reaction and associated pH gradients in porewaters

TL;DR: In this paper, a diagenetic model is presented that describes the effects of the steady-state reaction between oxygen and sulfide on pH distributions in porewaters, including consumption of O2 and sulfides and the production of H+ by this oxidation reaction.

Metals and models: Diagenic modelling in freshwater lacustrine sediments

TL;DR: In this paper, a review aims to distill and synthesize the existing information on the use of models to describe and predict the distribution and movement of metals in lacustrine sediments, examining the causes of metal diagenesis, the origin and form of the equations that govern these phenomena, and the predictability or measurability of the parameters that appear in the models.

Experimental Investigations of the Weathering of Suspended Sediment by Alpine Glacial Meltwater

TL;DR: In this article, a suite of controlled laboratory experiments was used to investigate the magnitude and processes of solute acquisition by dilute meltwater in contact with suspended sediment in the channelized component of the hydroglacial system.
