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.
Obsidian is an example of an igneous rock that emerges as lava and cools, and granite is typically formed as a pluton under the crust. Sedimentary rock is formed after rocks of other types erode away from their beds and are transported to a common dump site. The character of sedimentary rocks is largely determined by the grains that go into it.
