Intrusive igneous rocks form when.

Is granite an example of intrusive igneous rock.

It forms from the slow crystallization of magma below earth s surface. The result is a coarse grained rock phaneritic example. 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. 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.

Intrusive or plutonic igneous rocks form when magma cools slowly below the earth s surface most intrusive rocks have large well formed crystals. 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 has mineral crystals that can be seen clearly with the naked eye. At these depths magma is insulated by the rocks around it and cools very slowly growing large interlocking crystals.

There are two basic types. Molten rock that has erupted onto the earth s surface. 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. 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.

Igneous rocks are those that form via the process of melting and cooling. Magma crystallizes slowly underground. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. Igneous rocks are formed from the solidification of molten rock material.

What are igneous rocks. Granite is an intrusive igneous rock which means it crystallized from molten rock called magma miles underground. Intrusive rocks that crystallized at depths of several km. Granite is the most common intrusive igneous rock as the continental crust is composed of granite.

Examples include granite gabbro diorite and dunite. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.
