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.

Influence of carbonation on leaching of cementitious wasteforms

TL;DR: In this article, a combined experimental and modeling approach was used to evaluate the role of carbon dioxide in the long-term performance of cementitious waste forms, and the results showed that carbonation slowed the diffusional release of strontium and increased the release of nitrate, calcium, cadmium, lead and cobalt.

Geochemistry of Great Salt Lake, Utah I: Hydrochemistry since 1850

TL;DR: The hydrochemistry of the Great Salt Lake, Utah, has been defined for the historic period, 1850 through 1982, from published data combined with new observations as discussed by the authors, and the authors have used calculated evaporation curves with mineral precipitation and dissolution to clarify these processes.

The geochemistry of iodine in near-shore carbonate sediments

TL;DR: In this paper, the diagenetic behavior of I was examined in the Fe-poor carbonate sediments of Florida Bay, Florida, and it was shown that I is released by organic decomposition at I/C ratios similar to terrigenous environments.

4 Modeling Biogeochemical Cycles

TL;DR: In this article, the basic concepts used in the description and modeling of biogeochemical cycles are introduced and defined, including the turnover time, the ratio between the content (M) of a reservoir and the total flux out of it (S), and the residence time, defined as the time spent in a reservoir by an individual atom or molecule.
