High fluid pressures during regional metamorphism and deformation: Implications for mass transport and deformation mechanisms

Abstract: Evidence is presented to support the conclusion that pore fluid pressures tresses PF during regional metamorphism are generally greater than or equal to the minimum principal compressive stress S3. The resultant very low effective stresses σ lead to significantly increased porosity and permeability, even at moderate to high metamorphic temperatures. Permeabilities between 10−18 and 10−15 m2 and are considered to be common, resulting in rapid fluid migration and the dominance of advective (infiltrative) over di… Show more

“…data, 1994). There is also a fundamental problem in the argument that the rapid pressure drop during hydrofracturing causes supersaturation of solute species and consequent increment of fiber growth (e.g., Etheridge et al, 1984). Although sudden pressure drops do cause supersaturation of most solute species such as quartz, calcite is more soluble as fluid pressure increases (Bruton and Helgeson, 1982), yet quartz and calcite fibers commonly occur together as fibers in "crack-seal" veins.…”

“…Supersaturation of solute phases caused by the pressure drop during crack propagation, discussed above, has been proposed as the mechanism to cause mineral precipitation resulting in sealing of the crack (Etheridge et al, 1984). This explanation is attractive for minerals such as quartz, but calcite (and aragonite) is more soluble as fluid pressure increases (Bruton and Helgeson, 1982).…”
