Question

Quizplus · Accepted Answer

A laccolith is a type of igneous intrusion that is characterized by a mushroom-like shape, with a flat bottom and a rounded top. It forms when magma is injected into a horizontal sedimentary layer, causing it to bulge upwards and form a dome-shaped structure. Unlike a dike, which is a vertical intrusion that cuts across layers of rock, a laccolith remains entirely within the layer of rock it was injected into. Unlike a volcanic neck, which is a remnant of a volcano's throat, a laccolith is not directly associated with volcanic activity. Finally, a batholith is a much larger, more extensive intrusion.
