Any type of magma body can lead to contact metamorphism, from … WebContact 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 penetrated with fluid from the magma. The area affected by the contact of magma is usually small, from 1 to 10 kilometers. Contact metamorphism produces non-foliate rocks

WebDec 16, 2014 · 1 Answer Julian M. Dec 16, 2014 Foliation in metamorphic rock is formed by uni- or bi-directional strain, often under high temperature and pressure conditions, that allow laminar deformation along planes of weakness between layers, mineral grains, and molecular bonds. 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 happens when a body of magma intrudes into the upper part of the crust. Heat is important in contact metamorphism, but pressure is not a key factor, so contact metamorphism produces non-foliated metamorphic rocks … WebAt shallow depths within the crust (usually less than 6 km) the heat sources responsible for contact metamorphism are bodies of hot magma (e.g. igneous intrusions) which raise the temperature of the surrounding rocks. These thermal affects are usually restricted to the contact zones of the intrusions, hence the term contact metamorphism.
