Word Origin and History for intrusions
Online Etymology Dictionary, © 2010 Douglas Harper
- The movement of magma through cracks in underground rocks within the Earth, usually in an upward direction.♦ Rocks that form from the underground cooling of magma are generally coarse-grained (because they cool slowly so that large crystals have time to grow) and are called intrusive rocks. Compare extrusion.
