WebbMetamorphic rocks are formed through the transformation of pre-existing rocks in a process known as metamorphism (meaning “change in form”). The original rock, or protolith, is subjected to heat and pressure which cause physical, chemical and mineralogical changes to the rock. Protoliths may be igneous, sedimentary or pre … WebbMetamorphic source rocks, the rocks that experience the metamorphism, are called the parent rock or protolith, from proto – meaning first, and lithos- meaning rock. Most metamorphic processes take place deep underground, inside the earth’s crust.

WebbHeat is generated by the friction of sliding along such a shear zone, and the rocks tend to be mechanically deformed, being crushed and pulverized, due to the shearing. Cataclastic metamorphism is not very common and is restricted to a narrow zone along which the shearing occurred. Hydrothermal Metamorphism. Webb1 okt. 2011 · Schematic P-T-t paths for Barrovian metamorphism. Pressure-Temperature-time paths. This post is in the middle of a series on metamorphism.
