What is Contact Metamorphism and Igneous Intrusions about?
The document discusses contact metamorphism, which occurs when heat from igneous intrusions alters surrounding rocks, leading to changes in mineral composition and the formation of a baked margin. It explains the processes involved, including thermal alteration and the formation of high-temperature minerals, as well as examples like the Sulitjelma Gabbro and Cliffe Hill Quarry. The document also highlights the importance of temperature and time in determining metamorphic grade and the chemical changes that
