Abstract
A knowledge of how fluids behave during regional metamorphism is central to any understanding of metamorphic processes, but studies of regional fluid migration are still in their infancy, and there is considerable controversy about the possible role of migrating fluids in metamorphism. There can be no doubt that fluids are driven off from many rock types during progressive metamorphism and that fluid can reenter rocks after the peak of metamorphism to give rise to retrograde changes. However, major uncertainties remain concerning the permeabilities and porosities of rocks undergoing metamorphism, and even the widespread assumption by metamorphic penologists that fluid pressure (P f ) is approximately equal to lithostatic pressure (P l ) can seldom be independently verified.
