Experimental Perspectives of Mineral Dissolution and Precipitation due to Carbon Dioxide-Water-Rock Interactions

Rapid generation of reaction permeability in the roots of black smoker systems, Troodos ophiolite, Cyprus

“…In practice, many sites of dissolution would operate simultaneously, and a dyke could be fully altered in much less time than that. Rates for other minerals including clinopyroxene are similar, although rarely measured at higher temperatures (Brantley & Chen 1995;Chen & Brantley 1998;Bandstra et al 2008;Kaszuba et al 2013).…”

Fluids in the Continental Crust

“…An excellent summary of geochemical reaction rates applied to crustal environments is provided by Rimstidt (2014). The example of CO 2 injection into formation waters has already been introduced above, and it was noted that the surface reaction rates of carbonate minerals are significantly faster than those of silicates measured under comparable conditions (Pokrovsky et al, 2005Balashov et al, 2013;Kaszuba et al, 2013). When injected CO 2 dissolves into formation waters, lowering the pH, the acidity is likely to be neutralised by carbonate dissolution in the first instance.…”

Mineralization of Carbon Dioxide: A Literature Review

“…Intercalation could provide additional storage capacity for CO 2 in clay layers on reservoir rock coatings and in the caprock [51,58], and could also be a mechanism for controlling potential leakage [58,100,101]. Investigations into these aspects of scCO 2 behavior, at elevated pressures and temperatures characteristic of geologic carbon sequestration, have only recently begun [99,102].…”
