Schist is another type of metamorphic rock known for its distinct layered appearance. It forms from the alteration of shale or granite under high pressure and temperature conditions. The minerals in schist, such as mica, give it a shiny, reflective quality, making it visually striking. This rock is often used in construction and landscaping due to its durability and aesthetic appeal. Schist can vary in color, including shades of gray, green, and brown, depending on its mineral composition. Its unique texture and structure make it a popular choice for decorative stone in various applications.
