Quizplus · Accepted Answer

A laccolith is a mushroom-shaped igneous intrusion that forms when magma intrudes between layers of sedimentary rock, near the surface, and creates a dome or bulge upwards. This process is indeed a local inflation of a horizontal sill, distinguishing it from other types of intrusions like dikes, batholiths, and volcanic necks.
