A laccolith is a type of igneous intrusion that forms when magma is injected into the space between two rock layers and causes the overlying layer to bulge upward. This results in a dome-shaped mass of rock that is concave-upward, with a flat bottom and a rounded top. Batholiths are much larger intrusive bodies that form deep underground and are often exposed through erosion. Dikes are vertical or near-vertical intrusions of magma that cut through other rocks, while volcanic necks are solidified lava cores of extinct volcanoes that have been exposed by erosion.
