This type of metamorphic was created by regional … WebThe type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith. During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or …

Web6.1 Metamorphism and Plate Tectonics Metamorphism is the change that takes place within a body of rock as a result of it being subjected to conditions that are different from those in which it formed. In most cases—but not all—this involves the rock being deeply buried beneath other rocks, where it is subjected to higher temperatures and pressures … WebSome metamorphism occurs when water flows through a rock without significant changes in temperature or pressure. This kind of metamorphism, hydrothermal metamorphism often produces low-temperature alteration of country rocks. For example, Figure 9.24 is a photo of a serpentinite from near the Golden Gate Bridge in San Francisco, and Figure …
WebUnlike metamorphism, metasomatism can significantly change the overall chemistry of the parent rock. Elements commonly added during metasomatism are iron, sodium, potassium, oxygen, and silica. Easily soluble elements, such as calcium and magnesium from limestones, are often dissolved and carried away, creating more room for new chemical … WebMay 6, 2024 · While rocks can be metamorphosed at depth in most areas, the potential for metamorphism is greatest in the roots of mountain ranges where there is a strong likelihood for burial of relatively young sedimentary rock to great depths, as depicted in Figure \(\PageIndex{2}\). An example would be the Himalayan Range.
