A Compilation of Rate Parameters of Water-Mineral Interaction Kinetics for Application to Geochemical Modeling
TL;DR: In this paper, a general Arrhenius-type rate equation for over 70 minerals, including phases from all the major classes of silicates, most carbonates, and many other non-silicates, were derived from a computer code that simulates an infinitely well-stirred batch reactor, allowing computation of mass transfer as a function of time.
Journal ArticleDOI
Chemical weathering rate laws and global geochemical cycles
TL;DR: In this article, a rate law that integrates the effects of temperature, pH, ionic strength, and saturation conditions on the overall dissolution and precipitation rates of minerals is proposed, with special attention to the important effects of deviation from equilibrium on the rates of mineral-water reactions.

Thermodynamic and kinetic constraints on reaction rates among minerals and aqueous solutions. II. Rate constants, effective surface area, and the hydrolysis of feldspar
TL;DR: In this article, it was shown that the cross-sectional area of etch pits on hydrolyzed feldspar grains is of the order of 10−9 to 10−8 cm2 and that the ratio of the effective to total surface area (which may or may not change with reaction progress) ranges from <0.01 to 1, depending on the grain size, dislocation density, and the extent of comminution damage on the surfaces of the grains.

The Activated Complex in Chemical Reactions
TL;DR: In this paper, the probability of the activated state is calculated using ordinary statistical mechanics, and the probability multiplied by the rate of decomposition gives the specific rate of reaction, and necessary conditions for general statistical treatment to reduce to the usual kinetic treatment are given.

Interstitial Atomic Diffusion Coefficients
Charles Wert,Clarence Zener +1 more
TL;DR: In this paper, an attempt is made to interpret the temperature independent factor of the previously determined diffusion coefficients of interstitial solute atoms in metals, and the associated entropy factors are consistent with the theoretical range.

Estimation of underground temperatures from the silica content of water from hot springs and wet-steam wells
R. O. Fournier,J. J. Rowe +1 more
TL;DR: In this article, the authors used the silica content of boiling water discharged at the surface to estimate underground temperature of last equilibrium with quartz, provided correction is made for steam forming during solution ascent.

Systematic Packing of Spheres: With Particular Relation to Porosity and Permeability
L. C. Graton,H. J. Fraser +1 more
TL;DR: In this article, the underlying principles of porosity and permeability of uniform spheres are investigated, and the relationships disclosed, important wherever orderly distribution of points or particles is involved, are especially treated as the underlying principle.
