If magma makes it to the surface it will erupt and later crystallize to form an extrusive or volcanic rock. If it crystallizes before it reaches the surface it will form an igneous rock at depth called a plutonic or intrusive igneous rock.

The Miocene Searchlight pluton was tectonically tilted during the opening of the Colorado River Extensional Corridor in southern Nevada, exposing its ~10 km vertical extent. The pluton can be divided into three well- defined ... A comparable compositional transition of similar age is observed in this volcanic sequence,

Among igneous rocks, i.e. those formed from magma or molten rock, the most important difference may be between plutonic and volcanic rocks. ... In plutonic rocks, magma cools slowly and the crystals have time to grow large. They can grow very large indeed in a very slow cooling pluton. The rock with the largest crystals I...

In Richmond, boulders in the James River are remains of a vast area of molten rock known as a pluton -- a term in geology that refers to ancient magma -- liquid rock that hardens below the ... According to geologist Badger, some of the volcanic rocks in Shenandoah National Park date to between one and 1.2 billion years.

The Purvis Pluton is a calc-alkaline, east-west trending, moderate-sized (~3km3), volcanic arc-associated, sill-like multiphase dioritic to tonalitic intrusion with a strike length of 5.7 km and a thickness which ranges from 100-1200 meters.

Our evidence for overturn and downward displacement of these older volcanic strata during pluton emplacement is provocative given the expectation that such processes would be less ductile at these upper crustal levels.
