Is Granite An Example Of Intrusive Igneous Rock

Intrusive rocks that crystallized at depths of several km.

Is granite an example of intrusive igneous rock.

At these depths magma is insulated by the rocks around it and cools very slowly growing large interlocking crystals. Molten rock that has erupted onto the earth s surface. Basalt and gabbro are the extrusive and intrusive names for mafic igneous rocks and peridotite is ultramafic with komatiite as the fine grained extrusive equivalent. Granite has mineral crystals that can be seen clearly with the naked eye.

Igneous rocks are formed from the solidification of molten rock material. It forms from the slow crystallization of magma below earth s surface. Granite is a light colored plutonic rock found granite dikes are clearly igneous and granite emplaced in the zinc gold and silver for example igneous rocks are formed and created by igneous rocks are divided into two types granite is a coarse grained intrusive rock which contains the. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

Igneous rocks are those that form via the process of melting and cooling. Granite is an intrusive type of igneous rock also since it is intrusive it cools very slowly and forms large crystals and coarse large grained igneous rock. What are igneous rocks. There are two basic types.

Granite is an intrusive igneous rock which means it crystallized from molten rock called magma miles underground. Komatiite is a rare rock because volcanic material that comes directly from the mantle is not common although some examples can be found in ancient archean rocks 2. Granite is the most common intrusive igneous rock as the continental crust is composed of granite. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite.

Intrusive or plutonic igneous rocks form when magma cools slowly below the earth s surface most intrusive rocks have large well formed crystals. Examples include granite gabbro diorite and dunite. Intrusive igneous rocks form when. The result is a coarse grained rock phaneritic example.

If the intrusive rock cooled underground but near the surface it is called subvolcanic or hypabyssal and often has visible but tiny mineral grains. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form.
