How does contact metamorphism work

WebDynamic metamorphism, or cataclasis, results mainly from mechanical deformation with little long-term temperature change. Textures produced by such adjustments range from breccias composed of angular, shattered rock fragments to very fine-grained, granulated or powdered rocks with obvious foliation and lineation. WebContact metamorphism occurs primarily as a consequence of increases in temperature when differential stress is minor. A common phenomenon is the effect produced …

WebMay 11, 2024 · CONTACT METAMORPHISM: Contact metamorphism involves existing rocks coming into contact with intense heat. This heat generally comes from lava or magma. So, contact metamorphism involves the surrounding rock being burned from intense heat. Heat ranges from around 300° to over 800°C. WebContact metamorphism takes place where a body of magma intrudes into the upper part of the crust. Any type of magma body can lead to contact metamorphism, from a thin dyke to a large stock.

Contact Metamorphism - an overview ScienceDirect Topics

WebContact metamorphism occurs due to heating, with or without burial, of rocks that lie close to a magma intrusion. It is characterized by low P / T gradients, as strong thermal … WebContact metamorphism occurs when magma intrudes or forces its way into existing rock. The heat of the magma bakes the surrounding rocks causing them to change. This is a local event. The changes due to contact metamorphism are relatively small and are said to be low-grade metamorphism.
