Delve into the processes of metamorphism, examining the driving forces behind rock transformation, including confining pressure and differential stress. Discover various metamorphic textures and common rock types, such as garnet-mica schist. Learn about increasing metamorphic grades and different metamorphic environments, including contact, hydrothermal, and regional metamorphism. Investigate metamorphic zones, index minerals, and the formation of migmatites. Conclude by exploring the valuable resources derived from rocks and minerals, including metallic resources and fossil fuels for energy production.
