TLDR
The first edition of this chapter provided a brief review of the geochemistry of carbonate minerals, summarized general aspects of their thermodynamics and the kinetics of their precipitation and dissolution, and then used the natural division between deep-sea marine carbonates (chalks and pelagic muds) versus shoal-water carbonates to organize details of the formation, distribution, and subsequent diagenetic alteration of these phases as mentioned in this paper.Abstract:
The first edition of this chapter provided a brief review of the geochemistry of carbonate minerals, summarized general aspects of their thermodynamics and the kinetics of their precipitation and dissolution, and then used the natural division between deep-sea marine carbonates (chalks and pelagic muds) versus shoal-water carbonates (skeletal and nonskeletal materials) to organize details of the formation, distribution, and subsequent diagenetic alteration of these phases. A substantial focus in this treatment was thus the description of the behavior and fate of carbonate minerals in natural settings. In this chapter, this latter material appears largely unchanged. The aim in this revision is not simply to trudge through calcite, dolomite, and magnesite rate equations, detailed reviews of which are available elsewhere; instead, the intent is to provide background for the selective discussion of recent work on carbonate mineral surfaces (mostly calcite).read more

Coral Reefs and Changing Seawater Carbonate Chemistry
Joan A. Kleypas,Chris Langdon +1 more
TL;DR: In this article, the relationship between seawater carbonate chemistry and coral reef calcification is discussed, identifying the hurdles in understanding the two, and presenting a strategy for overcoming those hurdles.
Journal ArticleDOI
Diagenetically induced shear failure of fine-grained sediments and the development of polygonal fault systems
TL;DR: In this article, the authors suggest that diagenesis of clay-rich sediments can lead to shear failure under low confining stresses, and this has significant implications for shale gas exploration, CO2 sequestration and exploration for methane hydrates.

The Growth of Crystals and the Equilibrium Structure of their Surfaces
TL;DR: In this paper, it was shown that the rate of growth of a surface containing dislocations is proportional to the square of the supersaturation for low values and to the first power for high values of the latter.

SUPCRT92: a software package for calculating the standard molal thermodynamic properties of minerals, gases, aqueous species, and reactions from 1 to 5000 bar and 0 to 1000 ° C
TL;DR: The SUPCRT92 software package as discussed by the authors is a suite of three interactive FORTRAN 77 programs, including SPRONS92.DAT, which allows the calculation of the standard Gibbs free energy, enthalpy, entropy, heat capacity, and volume of each reaction specified on the RXN file through a range of conditions specified on CON file.
