Kinetics of reactions between aqueous sulfates and sulfides in hydrothermal systems
Hiroshi Ohmoto,Antonio C. Lasaga +1 more
TL;DR: In this article, a second order rate law was established for the partial exchange of sulfur isotopes between aqueous sulfates and sulfides in a Na-bearing H2-pH system.
Book ChapterDOI
An Improved Geochemical Model of Atmospheric CO2 Fluctuations Over the Past 100 Million Years
Journal ArticleDOI
Multicomponent exchange and diffusion in silicates
TL;DR: In this article, an ionic diffusion model, similar to one proposed by workers in ceramics, is described and applied to the evaluation of diffusion coefficients, Dij, from tracer diffusion values.
Journal ArticleDOI
Isotopic exchange in mineral-fluid systems. I. Theoretical evaluation of oxygen isotopic exchange accompanying surface reactions and diffusion
TL;DR: In this article, the rate constants for the first type of mechanism are related as follows: r= −(1−F)(WS) (W+S)tA where W and S are the number of moles of oxygen in the fluid and solid, respectively, A is the surface area, t is time and F is the fraction of oxygen isotopic exchange.
Journal ArticleDOI
The kinetics of dissolution of nepheline (NaAlSiO4)
TL;DR: Tole and Lasaga as mentioned in this paper showed that the dissolution rate of nepheline is determined by the ratio of the rate of input of an ion into solution by dissolution and its removal from solution by precipitation or adsorption, such that, for a first order precipitation reaction, C final = Ak + A'k − + C ieq, where A is the surface area of the precipitated phase.
