Main settings of metamorphism

WebThere are two main types of metamorphism: Contact metamorphism—occurs when magma contacts a rock, changing it by extreme heat (Figure 4.14). Regional … Metamorphism occurring at increasing pressure and temperature conditions is known as prograde metamorphism, while decreasing temperature and pressure characterize retrograde metamorphism. Metamorphic petrology is the study of metamorphism. Meer weergeven Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of 150 to 200 °C (300 to 400 … Meer weergeven Regional Regional metamorphism is a general term for metamorphism that affects entire regions of the Earth's crust. It most often refers to … Meer weergeven Metamorphic processes act to bring the protolith closer to thermodynamic equilibrium, which is its state of maximum stability. For example, shear stress (nonhydrodynamic stress) is incompatible with thermodynamic equilibrium, so sheared … Meer weergeven 1. ^ Marshak 2009, p. 177. 2. ^ Vernon 2008, p. 1. 3. ^ Yardley 1989, pp. 1–5. 4. ^ Yardley 1989, p. 5. 5. ^ Yardley 1989, pp. 29–30. Meer weergeven Metamorphism is the set of processes by which existing rock is transformed physically or chemically at elevated temperature, without actually melting to any great degree. The importance of heating in the formation of metamorphic rock was … Meer weergeven Metamorphic rocks are classified by their protolith, if this can be determined from the properties of the rock itself. For example, if examination of a metamorphic rock shows that its protolith was basalt, it will be described as a metabasalt.
