How is schist made
WebThe heating and compression of clay-rich, bed sedimentary rocks called shale creates a series of rock types of increasing metamorphic grade: slate, filite, schist and gneiss. During the metamorphism of the shales and sometimes during the volcanic ash layers, the metamorphism transforms platy clay minerals into small mica layers. WebThese make up “New” Appalachia—the shales, sandstones, limestones, and coals that were formed as sediments were deposited, stratified, and solidified over geologic time. During the Carboniferous Period (358.9 to 298.9 million years ago), this long process included the formation of some of the richest coal beds in the world.
