Regional vs Contact Metamorphism Explained by Elysha Henry is a document available to read on EtoBox.
Regional metamorphism occurs over large areas due to tectonic events and high pressure at depth, resulting in foliated metamorphic rocks like slate, schist, and gneiss. Contact metamorphism occurs on a smaller scale near intrusions of magma, where high heat causes metamorphism in country rocks depending on temperature, forming non-foliated rocks such as hornfels, marble, and quartzite. The key differences are that regional metamorphism is driven by pressure at depth while contact metamorphism is driven by h
