WebbThe 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 alteration … Webb12 apr. 2024 · The Takanuki metamorphic rocks have been subjected to Amphibolite to Granulite facies metamorphism by the medium-P Takanuki metamorphism in the Early …

WebbMetamorphism 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 than those under which it formed. Webb3. Sample R is highly desired in the energy industry because it is the most “clean” variety. Using your knowledge of metamorphic processes, how do you think this rock becomes so “clean” compared to its protolith? Anthracite is the most metamorphosed form of coal. Its formed due to higher than normal heating, and contains more fixed carbon than other … WebbMetamorphism of Different Protoliths Protoliths (other than already metamorphosed rocks) may be of either magmatic or sedimentary origin.
