Plutonic rock

A rock formed at considerable depth by crystallization of magma and/or by chemical alteration. It is characteristically medium- to coarse-grained, of granitoid texture.

This category is also used for plutonic rock (phaneritic), mafic rock and plutonic rock (phanerit.

Alabama

Talladega Group; Lay Dam Formation, unnamed diamictite facies (Silurian?-Devonian): Talladega Group; Lay Dam Formation, unnamed diamictite facies - Unnamed diamictite facies of Lay Day Formation in Coosa and Chilton Counties consists of cobbles and boulders of carbonate, pelitic rocks, quartzite, chert, felsic plutonic rocks, and gneiss in a metagraywacke matrix.

California

pre-Cenozoic granitic and metamorphic rocks undivided (Early Proterozoic to Late Cretaceous): Granitic and metamorphic rocks, mostly gneiss and other metamorphic rocks injected by granitic rocks. Mesozoic to Precambrian.
Undated granitic rocks, unit 1 (Chocolate Mountains) (Oligocene to Miocene): Undated granitic rocks unit 1
Undated granitic rocks, unit 2 (Western Klamath Mountains) (Late Triassic to Early Jurassic): Undated granitic rocks unit 2
Undated granitic rocks, unit 3 (Southern California) (Jurassic(?) to Cretaceous(?)): Undated granitic rocks unit 3

Massachusetts

Massive quartz and silicified rock (Precambrian to Phanerozoic): Massive quartz and silicified rock .

Montana

Pre-Belt gneiss, schist, and related rocks (Archean Proterozoic(?) preCambrian-Proterozoic(?) preCambrian(?) Phanerozoic | Paleozoic(?) Mesozoic(?) Cenozoic | Cambrian(?) Ordovician(?) Silurian(?) Devonian(?) Carboniferous(?) Permian(?) Triassic(?) Jurassic(?) Cretaceous(?) Tertiary): Pre-Belt gneiss, schist, and related rocks: comprises all the rocks older than the Belt series except the Stillwater complex. These include the Cherry Creek group, consisting of interlaminated gneiss, schist, marble, and quartzite; and the Pony series of Tansley and others, consisting of gneiss and schist of both sedimentary and igneous origin. Recent work has resulted in the distinction of small masses of granitic and injected rocks now regarded as resulting from intrusion in Cretaceous or Tertiary time. Other such masses may have escaped recognition.

Rhode Island

vein quartz (Triassic?): vein quartz - En echelon and crosscutting veins (millimeter to meter widths) of massive quartz; crystal terminations common in vugs and open cavities. Contains local concentrations of cryptocrystalline jasper and quartz, and irregular distributions of hematite and goethite, some in botryoidal masses. Locally present are abundant rectangular crystals of barite (up to 2 cm), or hollow molds after dissolved barite. Age uncertain, but rocks lack deformation features present in nearby Pennsylvanian rocks of the Narragansett Basin; emplacement most likely postdates Alleghanian deformation

Older Precambrian metamorphic rocks in southeastern Utah (Precambrian)
Older Precambrian metamorphic rocks in southwestern Utah (Precambrian)
