Metamorphism is the process by which pre-existing rocks, known as protoliths, undergo physical and chemical changes due to variations in their environment, primarily temperature, pressure, and chemically active fluids, without the rock melting. Several factors influence the extent, type, and nature of metamorphism, and understanding these factors is crucial in petrology to interpret the history and evolution of the Earth's crust. Temperature is one of the most critical factors affecting metamorphism. As rocks are subjected to elevated temperatures, the minerals within them become unstable and recrystallize into new minerals that are stable under the new thermal conditions. The degree of metamorphism typically increases with temperature, ranging from low-grade metamorphism, where clays transform into chlorite, to high-grade metamorphism, where feldspars,
