Romano et al. (2024): Element mobility during basalt-water-CO2 interaction: observations in natural systems vs. laboratory experiments and implication for carbon storage

Pierangelo Romano, Lorenzo Brusca, Marcello Liotta IN: Geochemical Transactions, https://doi.org/10.1186/s12932-024-00087-7

Here, the authors present a data compilation of the chemical composition of waters circulating in basalt aquifers worldwide and the results of simple basalt-water-CO₂ experiments. Induced or naturally occurring weathering of basalts rocks release elements in waters and elemental concentration is closely dependent on water CO₂ concentration (and hence on water pH). They also performed two series of experiments where basaltic rock powder interacts with CO₂-charged waters for one month at room temperature.
