- Geologists study plutonic igneous rocks to understand the history of volcanic activity in the area.
- plutonic rocks
- plutonic igneous
Examples
-
If this second, now apparently ruling, paradigm were correct, felsic plutonic rocks should be somewhat more mafic than their supposed complementary volcanic fractions, but this is not supported by the statistical evidence.
Academic text (2018) -
Are the microstructures in plutonic igneous rocks comparable to those in granulites?
Academic text (2018) -
Such fabrics are not generally observed in plutonic rocks, in which plagioclase crystals are instead generally elongated parallel to (010).
Academic text (2018) -
Ground behavior and tunneling conditions in approximately 400 feet of the Lower Tunnel were expected to differ significantly from the upper portion because of the anticipated presence of harder and more abrasive plutonic and metasedimentary rock units in the tunnel horizon.
Academic text (1996) -
The main argument against grain annexation and coalescence as the primary processes that result in the formation of coarse-grained textures in plutonic rocks is based on the likely extent of undercooling in large intrusions.
Academic text (2018) -
During solidification at rates typical of plutonic magmas (as mentioned above), the initial degree of undercooling is generally sufficiently small that grain growth is controlled by the kinetics of attachment at the solid-liquid interface.
Academic text (2018) -
Granite is a common type of plutonic rock formed from cooled magma below the Earth's surface.
-
The plutonic rocks show distinct mineral structures due to their formation deep underground.

Etymology
Plutonic comes from the Greek name Plouton (the god Pluto), whose home was the 'underworld' deep below the earth. So plutonic describes rocks that form deep under the Earth's surface (not at a volcano) and cool slowly to make large crystals.
