WebDec 4, 2024 · Metamorphic rocks form as the result of a solid-state transformation of preexisting rocks. Parent rock or protolith is the term for the preexisting rock that is metamorphosed. The main agents of metamorphism (which means “to change”) are heat, pressure, and chemically active fluids. WebApr 16, 2014 · Metamorphic Processes • Recrystallization: The most common process in the formation of metamorphic rocks is recrystallization. In this process the grains making up the protolith change shape and size. The identity of the mineral does not change during this process, only the texture. Recrystallization occurs due to heating of the protolith.
WebTypes of metamorphic processes. All of these factors vary widely and result in different types of metamorphism depending upon which factor is dominant. The three main types of metamorphism are: Contact (also known as thermal) metamorphism: this is produced by high temperature, low pressure, low strain and variable fluid pressure. It is normally ... WebAug 4, 2024 · Deformation microstructures of peak metamorphic conditions in ultrahigh-pressure (UHP) metamorphic rocks constrain the rheological behavior of deeply subducted crustal material within a subduction channel. However, studies of such rocks are limited by the overprinting effects of retrograde metamorphism during exhumation. Here, we …
