Of or pertaining to Pluto; Plutonian; hence, pertaining to the interior of the earth; subterranean.
Of, pertaining to, or designating, the system of the Plutonists; igneous; as, the Plutonic theory.
(ploo tahn' ic) - Igneous rocks that form from the cooling of magma in the interior of a planet or asteroid.
describes igneous rocks formed deep beneath the earth's surface
Plutonic rocks are igneous rocks that crystallize below the earth’s surface. They are characterized by visible crystals arranged in a three-dimensional interlocking mosaic.
of igneous rock that has solidified beneath the earth's surface; granite or diorite or gabbro
Related to the cooling of molten materials within the earth. A pluton is a body of hot material that rises within the earth because it is less dense that the material around it. When this material cools before breaking the surface, it forms plutonic, or intrusive, rocks.
An igneous rock, or relating to igneous rock, that crystallized below the surface of the earth. The crystals in a plutonic rock are the size of grains of sugar or larger.
pertaining to igneous rock formed at great depth. A plutonic rock is coarse-grained due to slow cooling underground.
Refers to rocks of igneous origin that have come from great depth.
Applies to igneous rocks formed beneath the surface of the Earth; typically with large crystals due to the slowness of cooling. Synonym of intrusive. Antonym of volcanic.
eruptive or igneous rock consolidated at depth.
having to do with a class of intrusive igneous rocks that have solidified far below the earth's surface; or or having to do with the theory that the present condition of the earth's crust is mainly due to igneous action. [AHDOS
