The protolith subjected to metamorphism
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 … WebbThe parents rock subjected to metamorphism-can be igneous sedimentary or metamorphic rock.

The protolith subjected to metamorphism
Did you know?
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure of 100 megapascals (1,000 bar) or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. Th… WebbThe protolith subjected to metamorphism This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See …
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.

Webb27 maj 2024 · This article reports new geochemical, Sr-Nd-Hf-Pb and Re-Os data on the rocks of the Middle Paleoproterozoic (1.99 Ga) Tiksheozero ultramafic-alkaline-carbonatite complex confined to the northeastern margin of the Karelian Craton. We focus on the poorly studied silicate rocks. Based on petrographic and geochemical research, the … WebbMetamorphism 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 °F), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation.

High heat can cause rock minerals to recrystallize in the process of metamorphism. Rocks that are buried deep in Earth are subjected to equal pressure from all directions. This confining pressure can cause a phase chang e but does not fold rocks.
