Interaction between carbon bearing fluids and silicate minerals in mafic and ultramafic rocks during weathering or low grade metamorphism generally leads to the formation of carbonate minerals. The total consumption of carbon by silicate weathering alone has been estimated to be ∼150 Mt/year (Gaillardet et al., 1999; Hartmann et al., 2009), while carbonation of basaltic lavas on the sea floor accounts for ∼10 Mt/year (Alt and Teagle, 1999). By comparison, the current anthropogenic carbon emission is about 10 Gt/year.

Natural mineral carbonation is thus a significant component in the global carbon cycle and...
