Contact metamorphism temperature and pressure
Web1Metamorphic Rocks: Changing Rocks 2Lecture Summary • Metamorphism (process of change) • Deformation (directed pressure) • Types of metamorphism – contact, regional, burial, seafloor • Naming metamorphic rocks – hornfels, slate, phyllite, schist, and gneiss WebContact metamorphism is metamorphism in which high temperature is the dominant factor. However the confining pressure is relatively low. It is generally restricted to shallow depths in the Earth. Contact metamorphism does not show foliation. The majority of metamorphic rock found on Earth's surface are products of regional metamorphism.

WebThe facies of contact metamorphism progress in temperature at relatively low pressure from the Albite-Epidote Hornfels Facies to the Hornblende Hornfels Facies, to the Pyroxene Hornfels Facies. Xenoliths picked up by the magma may be metamorphosed to the Sanidinite Facies, but such rocks are relatively rare. barbalat’s lemmaWebAs discussed previously, contact metamorphism occurs as a result of a high geothermal gradient produced locally around intruding magma.
