There are two basic types.

The igneous rock granite intermediate.

Granodiorite is a plutonic igneous rock formed by intrusion of silica rich magma which cools in batholiths or stocks below the earth s surface. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. Acidic rocks such as granite microgranite and rhyolite are rich in silica and contain the minerals quartz feldspar and biotite among others. Each has a different composition according to where its magma collected.

Igneous rocks are formed from the solidification of molten rock material. Felsic igneous rocks containing a excessive silica content more than 63 sio2 examples granite and rhyolite intermediate igneous rocks containing among fifty two 63 sio2 example andesite and dacite mafic igneous rocks have low silica forty five fifty two and typically high iron magnesium content material example gabbro and. It is usually only exposed at the surface after uplift and erosion have occurred. Andesite magma is characterized by intermediate temperatures and viscosities resulting in both passive lava and violent pyroclastic eruptive styles.

Igneous rock any of various crystalline or glassy rocks formed by the cooling and solidification of molten earth material igneous rocks constitute one of the three principal classes of rocks the others being metamorphic and sedimentary. Of the hundreds of named igneous rocks consider the three rocks granite andesite and basalt. Granite is a type of igneous rock that consists of quartz gray plagioclase feldspar white and alkali feldspar beige plus dark minerals such as biotite and hornblende. Ultramafic rocks are dominated by olivine and or pyroxene.

Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form. Andesite is an extrusive volcanic rock with a composition that is intermediate between basalt and rhyolite. Granite is used by the public as a catchall name for any light colored coarse grained igneous rock. What are igneous rocks.

The name comes from two related rocks to which granodiorite is an intermediate. Igneous rocks are classified according to their mineral content. Intermediate rocks are roughly even mixtures of felsic minerals mainly plagioclase and mafic minerals mainly hornblende pyroxene. Igneous rocks are formed from the solidification of magma which is a hot 600 to 1 300 c or 1 100 to 2 400 f molten or partially molten rock material.

Typical intermediate rocks include andesite dacite and trachyandesite among volcanic rocks and diorite and granodiorite among plutonic rocks. The type of igneous rock determined by its mineral composition can be gauged from its relative darkness.
