Origin and timing of stratabound dolomitization in the Cretaceous carbonate ramp of Benicàssim [PDF]

, 2015
Hydrothermal dolomitization is one of the most important processes that may enhance or degrade carbonate porosity and permeability. Burial, high emperature or hydrothermal dolomite forms due to the interaction of one or more solutions, mainly seawater ...
