The maximum possible temperatures obtained from the intersections between isochores and P max line (for a depth of 8 km) are used to depict all possible FLUID-1 …
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.
