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.

Soil armouring and weathering: toward catchment-scale computational modelling.

TL;DR: In this article, a Markov process conceptualisation was used to reduce the complexity of ARMOUR's numerics and a new model called MrARM was proposed to simulate the effect of surface armouring and weathering on erosion and soil grading.

TL;DR: In this paper , the physical processes that affect early marine carbonate cementation in a bank-barrier reef were investigated using porewater geochemical and sedimentary data collected from the seafloor.

Aspects of Subsurface Brine Formation in Passive Continental Margin Evaporite Basins.

TL;DR: In this paper , a finite difference model is developed to evaluate the role of molecular diffusion of dissolved NaCl in the subsidence history of a hypothetical sedimentary basin containing a thick basal halite bed.

Inclusion of slow infiltration in determining the influence time of saline sediments on reservoir water

TL;DR: In this article, an alternative expression of Peclet number ( Pe = uC D ∂ C / ∂ x x = 0 ) is proposed to characterise the transient relative role of downward advection versus upward diffusion on the transport of nonreactive solutes; Pe can be used as an exact criterion for identifying the critical moment when saline sediments no longer affect the overlying water.
