Metamorphic Agents and Changes• Temperature: : typically themost important factor inmetamorphismFigure 1-9. Estimated ranges of oceanic andcontinental steady-state geotherms to a depth of100 km using upper and lower limits based on heatflows measured near the surface. After Sclater etal. (1980), Earth. Rev. Geophys. Space Sci., 18,269-311.
Metamorphic Agents and ChangesIncreasing temperature has several effects1) Promotes recrystallization → increased grainsize2) Drives reactions that consume unstablemineral(s) and produces new minerals that arestable under the new conditions3) Overcomes kinetic barriers that might otherwisepreclude the attainment of equilibrium
