Summary Of: MetamorphismMetamorphism produced with increasing pressure and temperature conditions is known as... The temperature lower limit of metamorphism is considered to be between 100... but some types of metamorphism can occur at extremely low pressures... The maximum temperature for metamorphism is typically between 700... Regional or Barrovian metamorphism covers large areas of... Regional metamorphism can be described and classified into... Contact metamorphism occurs typically around... where the contact metamorphism effects are present is called the... Rocks formed by contact metamorphism may not present signs of strong deformation and are often fine... Contact metamorphism is greater adjacent to the intrusion and dissipates with distance from the contact... metamorphism is the result of the interaction of a rock with a high... produces extensive hydrothermal metamorphism adjacent to spreading centers and other submarine volcanic areas... This kind of metamorphism occurs when either an extraterrestrial object... Dynamic metamorphism is associated with major... Metamorphism is localised adjacent to the fault plane and is caused by frictional heat generated by... dynamic metamorphism is not often produced because the confining pressure is too low to produce frictional heat... with dynamothermal metamorphism observed rarely as the growth of... resulting in conductive heat transfer and localised contact metamorphism of the cooler blocks adjacent to the hotter blocks... and often retrograde metamorphism in the hotter blocks... Metamorphism is further divided into prograde and retrograde metamorphism... Prograde metamorphism involves the change of mineral assemblages... Prograde metamorphism results in a rock representing the maximum pressure and temperature experienced... Retrograde metamorphism involves the reconstitution of a rock under decreasing temperatures... allowing the mineral assemblages formed in prograde metamorphism to return to more stable minerals at the lower pressures...
