Granodiorite is a plutonic igneous rock formed by intrusion of silica rich magma which cools in batholiths or stocks below the earth s surface.

Is granite a plutonic intermediate rock.

Depending on their silica content they are called in ascending order of silica content gabbro diorite granite and pegmatite. Typical intermediate rocks include andesite dacite and trachyandesite among volcanic rocks and diorite and granodiorite among plutonic rocks.

Plutons range in. Therefore plutonic rocks have coarse grained crystals. Thus a representative plutonic rock would be granite while representative in turn of volcanic rock would be basalt besides the difference between the large crystals of the former and the microscopic crystals of the latter they contrast markedly in color. Principal minerals feldspar quartz hornblende micas.

Although there are many rocks that resemble granite they are not all true granites. The name comes from two related rocks to which granodiorite is an intermediate. Si saturated to oversaturated. A good example is granite which is a very hard plutonic rock.

Applying this definition requires the mineral identification and quantification abilities of a competent geologist. Granite is a felsic plutonic rock composing the base of most of the continental crust. Most common batholiths are quartz diorite tonalite granodiorite granite. The name for a particular plutonic rock depends on the mix of minerals in it.

In ascending order four types include gabbro dark in color not much silica diorite an intermediate amount of silica granite 68 percent silica and pegmatite. Felsic plutonic rocks granitoids characteristics. Pluton is the term used to describe a mass of plutonic rock. Differences between plutonic and volcanic rocks are more complex and more revealing of the geological evolution of the earth.

In igneous petrology an intermediate composition refers to the chemical composition of a rock that has 52 63 wt sio 2 being an intermediate between felsic and mafic compositions. Mineralogically granite contains quartz various feldspars and micas. It is usually only exposed at the surface after uplift and erosion have occurred. Granite is a plutonic rock in which quartz makes up between 10 and 50 percent of the felsic components and alkali feldspar accounts for 65 to 90 percent of the total feldspar content.

By quantity these are the by far most common rock types.
