Regional metamorphism causes a layered or platy structure in rocks called foliation.

Regional metamorphism as its name suggests works over much larger areas. Regional pressure dominated metamorphism occurs over large areas during periods of mountain building. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Foliated rocks are the result of intense pressure and sometimes to a lesser degree are also the result of heat.
