Contact vs Regional Metamorphism - Study.com

Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of 150 to 200 °C (300 to 400 °F), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. Metamorphism is distinct from weathering or diagenesis, which are changes that take place at or just beneath Earth's surface. WebMetamorphism involves the transformation of pre-existing rocks by _____. A. weathering and erosion. B. lithification. C. cementation and compaction. D. crystallization. E. heat … ruth dewitt bukater death

WebThere are three ways that metamorphic rocks can form. The three types of metamorphism are Contact, Regional, and Dynamic metamorphism. Contact Metamorphism occurs when magma comes in contact with an already existing body of rock. When this happens the existing rocks temperature rises and also becomes infiltrated with fluid from the magma.
