Rapid CO2 mineralisation into calcite at the CarbFix storage site quantified using calcium isotopes

At the CarbFix experimental site in Iceland, artificial removal of CO2 from the Earth’s atmosphere is investigated. The authors here propose a new method based on isotope fractionation calculations to estimate the efficiency of CO2 sequestration into calcite in basaltic groundwater settings.
