Regional Metamorphism
Regional metamorphism is a common, widespread type of metamorphism typically associated with mountain building, where large segments of Earth’s crust are intensely deformed by the collision of two continental crust … Read More

Contact, or Thermal, Metamorphism
Contact metamorphism, or thermal metamorphism, occurs in Earth’s upper crust (low pressure), when rocks immediately surrounding a molten igneous body are “baked” (high temperature). Because contact metamorphism does not involve … Read More
What Drives Metamorphism?
The agents of metamorphism include heat, pressure, directional stress, and chemically active fluids.During metamorphism, rocks may be subjected to all four metamorphic agents simultaneously.However, the degree of metamorphism and the … Read More
What Is Metamorphism?
Unlike some igneous and sedimentary processes that occur in surface or near-surface environments, metamorphism most often occurs deep within Earth, beyond our direct observation. Notwithstanding this significant obstacle, geologists have … Read More
