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.
Intrusive (Plutonic) Igneous Rock: Intrusive igneous rock is formed when magma cools and solidifies within small pockets contained within the planetâs crust. As this rock is surrounded by pre-existing rock, the magma cools slowly, which results in it being coarse grained â i.e. mineral grains are big enough to be identifiable with the naked eye.
