Definition: A pluton is a deep-seated intrusion of igneous rock, a body that made its way into pre-existing rocks in a melted form (magma) several kilometers underground, in the Earth's crust.
Volcanic rocks are rocks formed when lava cools and solidifies on the earth's surface. Volcanic rocks are also known as 'extrusive igneous rocks' because they form from the 'extrusion,' or eruption, of lava from a volcano.his differentiation between magma and lava is important when we consider the two classifications of igneous rock. This is because plutonic rocks are rocks formed when magma cools and solidifies below the earth's surface, and volcanic rocks are rocks formed when lava cools and solidifies on the earth's surface.
