Metamorphic Rocks (2193 words) |
 | Metamorphic grade is a general term for describing the relative temperature and pressure conditions under which metamorphic rocks form. |
| Within increasing pressure of metamorphism, the pore spaces in which the fluid resides is reduced, and thus the fluid is driven off. |
| The sequence of metamorphic facies observed in any metamorphic terrain, depends on the geothermal gradient that was present during metamorphism. |

Metamorphism - Wikipedia, the free encyclopedia (722 words) |
| Metamorphic facies are recognizable terranes or zones with an equilibrium assemblage of key minerals that were in equilibrium under specific range of temperature and pressure during a metamorphic event. |
| As expected, the contact metamorphic effects are greater adjacent to the intrusive rock and fade away toward the exterior of the aureole. |
| Hydrothermal metamorphism is the result of the interaction of a rock with a high-temperature fluid of variable composition. |
