Heat is important in contact metamorphism, but pressure is not a key factor, so contact metamorphism produces non-foliated metamorphic rocks …
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 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.
Webmetasomatism - process of changing a rocks composition with hydrothermal fluids - water has dissolved ions and volatiles - accelerates chemical reactions - alter rock by adding and removing elements Chemical precipitate The formation of non-clastic sedimentary rocks by chemical processes. WebAug 30, 2024 · The temperature for contact metasomatism may possibly ranging from 400 to 800⁰ C, or even higher. 3. The composition, size, shape, form and depth of formation of the intrusive body play important role in formation of contact metasomatism. 2. • Important sources of ore deposit are Fe, Cu, Zn, W, and other metals.
