Web1 jan. 2012 · Metamorphic devolatilization generates fluids at, or near, lithostatic pressure. These fluids are ultimately expelled by compaction. It is doubtful that fluid generation and compaction operate on the same time scale at low metamorphic grade, even in rocks that are deforming by ductile mechanisms in response to tectonic stress. Web13 aug. 2009 · Fluid pressure from microthermometry on the right vertical axes corresponds to formation depth if lithostatic conditions and a rock density of 2.5 g/cm 3 are assumed.
