In geology, an igneous intrusion (or intrusive body [1] or simply intrusion [2]) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. WebCommon coarse-crystalline rocks that cooled slowly in a magma chamber are granite or gabbro. In rocks that cool rapidly from lava after a volcanic eruption, these crystals may be too small to be visible with the naked …
