Unformatted text preview: metamorphism . The factors that cause this process are rising temperatures, rising pressure, and changing chemical environment. In addition, deformation resulting from movement of Earths crust develops foliation and thus strongly affects the texture of a metamorphic rock. 17.) The minerals and textures in a rock change as it is metamorphosed. Contact metamorphism affects rocks heated by a nearby igneous intrusion. Burial metamorphism alters rocks as they are buried deeply within Earths crust. In regions where tectonic plates converge, high temperature and deformation from rising magma and plate movement all combine to cause regional dynamothermal metamorphism. Hydrothermal metamorphism is caused by hot solutions soaking through rocks and is often associated with emplacement of ore deposits....
