What is a Lacolith?

Answer 1

When magma flows between rock layers and spreads upward, it sometimes pushes the overlying rock layers into a dome. The base of the intrusion is parallel to the rock layer beneath it.

Answer 2

A lacolith is a type of igneous intrusion where magma pushes up the overlying rock layers without actually breaking through the surface. This creates a dome-like structure with a flat base and a rounded top. Lacoliths are typically found in mountainous regions and are associated with the formation of volcanic or plutonic rocks.

Answer 3

when magma flows between rock layers and spreads upward, it some times pushes the overlaying rock layers into a dome.
