A 'pluton' in
geology is an
intrusive igneous rock body that crystallized from a
magma below the surface of the
Earth. Plutons include
batholiths,
dikes,
sills,
laccoliths,
lopoliths, and other igneous bodies. In practice, "pluton" usually refers to a distinctive mass of igneous rock, typically kilometers in dimension, without a tabular shape like those of dikes and sills. Batholiths commonly are aggregations of plutons. The most common rock types in plutons are
granite,
granodiorite,
tonalite, and
quartz diorite.
The term originated from ''
Pluto'', the ancient Roman god of the underworld. The use of the name and concept goes back to the beginnings of the science of geology in the late 1700s and the then hotly debated theories of
Neptunism,
Vulcanism and
Plutonism regarding the origin of
basalt.
