Granitoid

Index Granitoid

A granitoid or granitic rock is a variety of coarse grained plutonic rock similar to granite which mineralogically is composed predominantly of feldspar and quartz. [1]

Anorogenic magmatism

In geology anorogenic magmatism is the formation, intrusion or eruption of magmas in other settings than convergent plate margins such as continental collision and subduction where orogeny is common.

Continent

A continent is one of several very large landmasses of the world.

Convergent boundary

In plate tectonics, a convergent boundary, also known as a destructive plate boundary, is a region of active deformation where two or more tectonic plates or fragments of the lithosphere are near the end of their life cycle.

Crust (geology)

In geology, the crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite.

Erosion

In earth science, erosion is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth's crust, and then transport it to another location (not to be confused with weathering which involves no movement).

Feldspar

Feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.

Granite

Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture.

Granodiorite

Granodiorite is a phaneritic-textured intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar.

Hotspot (geology)

In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle.

Mantle plume

A mantle plume is an upwelling of abnormally hot rock within the Earth's mantle, first proposed by J. Tuzo Wilson in 1963.

Orogeny

An orogeny is an event that leads to a large structural deformation of the Earth's lithosphere (crust and uppermost mantle) due to the interaction between plate tectonics.

New!!: Granitoid and Orogeny · See more »

Pluton

In geology, a pluton is a body of intrusive igneous rock (called a plutonic rock) that is crystallized from magma slowly cooling below the surface of the Earth.

New!!: Granitoid and Pluton · See more »

Quartz

Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.

New!!: Granitoid and Quartz · See more »

Quartz diorite

Quartz diorite is an igneous, plutonic (intrusive) rock, of felsic composition, with phaneritic texture.

New!!: Granitoid and Quartz diorite · See more »

Quartz monzonite

Quartz monzonite or adamellite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars.

New!!: Granitoid and Quartz monzonite · See more »

Rift

In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics.

New!!: Granitoid and Rift · See more »

Sial

In geology, the term 'sial' refers to the composition of the upper layer of the Earth's crust, namely rocks rich in silicates and aluminium minerals.

New!!: Granitoid and Sial · See more »

Subduction

Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced or sinks due to gravity into the mantle.

New!!: Granitoid and Subduction · See more »

Syenite

Syenite is a coarse-grained intrusive igneous rock with a general composition similar to that of granite, but deficient in quartz, which, if present at all, occurs in relatively small concentrations (.

New!!: Granitoid and Syenite · See more »

Trondhjemite

Trondhjemite is a leucocratic (light-colored) intrusive igneous rock.

New!!: Granitoid and Trondhjemite · See more »

Volcanic arc

A volcanic arc is a chain of volcanoes formed above a subducting plate, positioned in an arc shape as seen from above.

New!!: Granitoid and Volcanic arc · See more »

Volcanic rock

Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from magma erupted from a volcano.
