A batholith is a pluton that can range from hundreds to thousand of cubic kilometers across and 10-30 km beneath the earth's surface. First during the creation process, buoyant magma starts to rise up towards the surface and gains passage into cracks left behind by faulting activities or by simply melting down the surrounding native rocks. Stocks are exposed over an area of less than 100 square kilometers, while batholiths are larger. The laccolith and lopolith are almost identical.
