Metamorphism can be instantaneous as in the shearing of rocks at plate boundaries or can take millions of years as in the slow cooling of magma buried deep under the surface of the Earth. These metamorphic rocks pervade regions that have been subjected to intense pressures and temperatures during the development of mountain chains along boundaries between crustal plates. Dynamic metamorphism is the result of very high shear stress, such as occurs along fault zones. All of these factors vary widely and result in different types of metamorphism depending upon which factor is dominant. Metamorphism […] These two types of metamorphism mainly differ from each other according to the area in which metamorphism takes place. This change occurs principally due to pressure, heat and the intervention of chemically active fluids. The three main types of metamorphism are: Contact (also known as thermal) metamorphism: this is produced Dynamic Metamorphism - reactions driven primarily by pressure at relatively low temperatures Which agent of metamorphism can cause the overall composition of the rock to change. Start studying Lecture 16: Types of Metamorphism and Tectonic Settings. In all types of thermal metamorphism the change is generally in the direction of mineralogical reconstitution. The various types of foliated metamorphic rocks, listed in order of the grade or intensity of metamorphism and the type of foliation are: slate, phyllite, schist, and gneiss (Figure 7.2.4). The major types of metamorphic rocks are detailed here, which include regional, contact and mechanical metamorphism. The word "Metamorphism" comes from the Greek: Meta t= change, Morph = form, so metamorphism … Skip to content. The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical change.The protolith may be a sedimentary, igneous, or existing metamorphic rock. As already noted, slate is formed from the low-grade metamorphism of shale, and has microscopic clay and mica crystals that have grown perpendicular to the stress. As per Wikipedia, “”Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means “change in form””.The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (1500 bars), causing profound physical and/or chemical change. The three main types of metamorphism are: Regional Metamorphism Contact Metamorphism Hydrothermal metamorphism Regional metamorphism is … Metamorphism may also take place as a result of a change in chemical environment; this may occur by transport of elements between chemically contrasting rock types (e.g., formation of calc-silicate minerals at a quartzite–marble contact) or by circulation of fluids that … Dynamic Metamorphism: Contact metamorphism is a type of metamorphism that occurs adjacent to intrusive igneous rocks due to temperature increases resulting from hot magma intrusion into the rock. Contact Metamorphism Contact Metamorphism. Types of Metamorphism Local Metamorphism. The deeper you go, the greater the pressure on the tunnels because of the weight of rock above. In this type, the metamorphic processes take place due to a combined effect of pressure and temperature increase. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". Types of metamorphism. Regional or Barrovian metamorphism covers large areas of continental crust typically associated with mountain ranges, particularly those associated with convergent tectonic plates or the roots of previously eroded mountains. It is one of the most pervasive and widespread types of metamorphism, although most of it cannot be seen easily. ... Types of Metamorphism. The metamorphosed zone is known as … Metamorphism can also occur when rocks grind together in fault zones or when meteorites impact Earth, leading to dynamic metamorphism.Dynamic metamorphism, also called shock metamorphism or cataclastic metamorphism, is an uncommon form of metamorphism.It occurs because of sudden pressure exerted by faults or meteorite impacts. Types of metamorphic processes. Dynamic Metamorphism Burial Metamorphism. Five types of metamorphic rock formation can be understood by the three ways by which metamorphic rocks can be formed. The region surrounding an intrusion, wherein metamorphism is gift, is referred to as a metamorphic aureole. So, the five types of metamorphism is discussed below: Contact Metamorphism. Moreover, contact metamorphism involves the contact of the rock with magma, while regional metamorphism involves collisions between continent-continent or oceanic and continental plates. October 22, 2016 tapniocharlesdominic Leave a comment. Rocks. Other types of metamorphism can occur. Types of Metamorphism Contact Metamorphism- This type of metamorphism occurs locally adjacent to the igneous intrusion; with high temp. What causes metamorphism of rocks? This video deals with the basics of metamorphism and types of metamorphism 1. S . Regional. What Are the Types of Metamorphosis? Dynamic metamorphism occurs at relatively low temperatures compared to other types of metamorphism, and consists predominantly of the physical changes that happen to …
