文摘
- •
We describe rock and mineral carbonation by fluid–rock interactions at HP conditions.
- •
We discuss the origin of COH fluids responsible for HP carbonation.
- •
We discuss the fate of carbonic fluids produced during subduction metamorphism.
- •
We discuss the impact of carbonation on carbon fluxes between subduction zone reservoirs.
