Laccolith
A small, igneous rock body emplaced at shallow depths by uplift and arching of the overlying, older strata is a laccolith.
The laccolith is an intrusive stone body with a dome-shaped upper surface and a level base.
The laccolith formed when the magma rising from the Earth's crust began to spread horizontally, separating the rock strata.
