Reservoir properties and reactivity of the Faroe Islands Basalt Group: Investigating the potential for CO2 storage in the North Atlantic Igneous Province
Offshore injection of CO2 into volcanic sequences of the North Atlantic Igneous Province may present a large-scale, permanent storage option through carbonate mineralization. To investigate this potential, onshore studies of reservoir properties and reactivity of the subaerially erupted Faroe Island...
