Dawsonite synthesis and reevaluation of its thermodynamic properties from solubility measurements: Implications for mineral trapping of CO2
TL;DR: This paper measured the solubility of synthetic dawsonite according to the equilibrium: NaAlCO3(O)2(cr)+2H2O(l)⇌Al(OH)4-+HCO3-+Na++H+, from under and oversaturated solutions at 50-200 °C in basic media at 1.0 mol · kg−1 NaCl.

Evolution of porosity and diffusivity associated with chemical weathering of a basalt clast
Alexis Navarre-Sitchler,Alexis Navarre-Sitchler,Carl I. Steefel,Carl I. Steefel,Li Yang,Li Yang,Liviu Tomutsa,Susan L. Brantley +7 more
TL;DR: In this article, the authors combine synchrotron X-ray microcomputed tomography (μCT) and laboratory and numerical diffusion experiments to examine changes in both total and effective porosity and effective diffusion coefficients across a weathering interface in a weathered basalt clast from Costa Rica.

Experimental identification of CO2–water–rock interactions caused by sequestration of CO2 in Westphalian and Buntsandstein sandstones of the Campine Basin (NE-Belgium)
TL;DR: In this paper, the authors evaluated the effect of CO 2 -water-rock interactions on three sandstone aquifers in NE-Belgium and found that dissolution of ankerite/dolomite and Al-silicates could enhance porosity/permeability.

Equations for calculating hydrogeochemical reactions of minerals and gases such as CO2 at high pressures and temperatures
TL;DR: In this paper, a more general and reliable calculation of apparent molar volumes of single ions is presented, based on a modified Redlich-Rosenfeld equation, using the Born equation to calculate the temperature dependence of the intrinsic volumes, following Helgeson-Kirkham-Flowers (HKF), but with Bradley and Pitzer's expression for the dielectric permittivity of water, and using the pressure dependence of extended Debye-Huckel equation to constrain the limiting slope of the molar volume with ionic strength, and adopting the convention

P. J. Armitage,Richard H. Worden,Daniel R. Faulkner,Andrew C. Aplin,Alan R. Butcher,J. Iliffe +5 more
TL;DR: In this paper, the authors analyzed 17 samples from Lower Carboniferous estuarine caprock to a gas field (also to be used as a carbon capture site), using a range of petrological and petrophysical techniques.
