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.

The effect of time on the weathering of silicate minerals: why do weathering rates differ in the laboratory and field?
Art F. White,Susan L. Brantley +1 more
TL;DR: In this article, the correlation between decreasing reaction rates of silicate minerals and increasing duration of chemical weathering was investigated for both experimental and field conditions, and it was shown that intrinsic surface area, which increases with the duration of weathering, was responsible for a third of the exponential decrease in the weathering rate.

Chemical weathering ,a tmospheric co 2 , and climate
TL;DR: There has been considerable controversy concerning the role of chemical weathering in the regulation of the atmospheric partial pressure of carbon dioxide, and thus the strength of the greenhouse effect and global climate.

Fungal production of citric and oxalic acid: importance in metal speciation, physiology and biogeochemical processes.
TL;DR: The physiology and chemistry of citric and oxalic acid production in fungi are discussed, the intimate association of these acids and processes with metal speciation, physiology and mobility, and their importance and involvement in key fungal-mediated processes, including lignocellulose degradation, plant pathogenesis and metal biogeochemistry.

The kinetics of silica-water reactions
J.D. Rimstidt,H.L. Barnes +1 more
TL;DR: In this article, the authors derived a differential rate equation for silica-water reactions from 0-300°C based on stoichiometry and activities of the reactants in the reaction SiO2(s) + 2H2O(l) = H4SiO4(aq) ( ∂a H 4 SiO 4 ∂t ) P.T.
