Origin of Meteoric Fluids in Extensional Detachments

Figure 1

Time for a spherical fluid-filled inclusion to reach 50% pressure equilibration, starting with a hydrostatic pressure (assuming  kg/m³) in a quartz matrix at lithostatic pressure (assuming  kg/m³). The geotherm is set at 30°C/km at a surface temperature of 15°C. Flow laws used are from Paterson and Luan [41] and Gleason and Tullis [42] (see Table 1).
