Is Granite An Example Of Intrusive Igneous Rock

Granite has mineral crystals that can be seen clearly with the naked eye.

Is granite an example of intrusive igneous rock.

Examples include granite gabbro diorite and dunite. 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. Igneous rocks are those that form via the process of melting and cooling. Molten rock that has erupted onto the earth s surface.

Intrusive or plutonic igneous rocks form when magma cools slowly below the earth s surface most intrusive rocks have large well formed crystals. If they erupt from volcanoes onto the surface as lava they are called extrusive rocks by contrast intrusive rocks are formed from magma that cools underground. Granite is an intrusive igneous rock which means it crystallized from molten rock called magma miles underground. The result is a coarse grained rock phaneritic example.

There are two basic types. What are igneous rocks. Intrusive igneous rocks form when. Granite is the most common intrusive igneous rock as the continental crust is composed of granite.

Magma crystallizes slowly underground. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. 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. At these depths magma is insulated by the rocks around it and cools very slowly growing large interlocking crystals.

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Igneous rocks are formed from the solidification of molten rock material. Intrusive rocks that crystallized at depths of several km. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form.

It forms from the slow crystallization of magma below earth s surface. 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.
