Schist

Schist is a type of metamorphic rock formed when existing rocks are subjected to intense heat and pressure deep within the Earth. This process causes the minerals in the rock to realign into thin, parallel layers, giving shist its characteristic foliated or flaky appearance. It often contains minerals like mica, which can make the rock shiny or reflective. Schist is commonly used in construction and decorative applications due to its durability and attractive layered look. Its formation reflects significant geological processes that transform the original rock over long periods, resulting in a visually distinctive and economically valuable resource.
