How does contact metamorphism work
WebThis is called Regional Metamorphism because large regions of rock are affected. However, rocks can also be metamorphosed at shallower depths if they are heated up by nearby intrusions of hot magma – this is called Contact Metamorphism. Regional Metamorphism Regional Metamorphism. 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.
