[lak-uh-lahyt] . [lak-uh-lit-ik] , adjective | laccolith (lāk'ə-lĭth') Pronunciation Key
A body of igneous rock intruded between layers of sedimentary rock, resulting in uplift. Laccoliths are usually plano-convex in cross-section, having a flat bottom and a convex top, and are roughly circular in plan. They are usually connected to a dike and are typically up to 8 km (5 mi) in diameter and tens to hundreds of meters thick. See illustration at batholith. |
