Is Granite A Common Igneous Rock

Intrusive means that it has moved into other rocks by force coming up from the mantle.

Is granite a common igneous rock.

Granite is the most widespread of igneous rocks underlying much of the continental crust. Granite is the best known igneous rock. Felsic rocks are less dense than mafic and ultramafic rocks and thus they tend to escape subduction whereas basaltic or gabbroic rocks tend to sink into the mantle beneath the granitic rocks of the continental cratons. Granite is possibly the most common igneous rock type known to the general public.

Granites can be predominantly white pink or gray in color depending on their mineralogy. There are two basic types. Many people recognize granite because it is the most common igneous rock found at earth s surface and because granite is used to make many objects that we encounter in daily life. Because it cools slowly crystals have time to form.

What are igneous rocks. Eventually the overlying rocks are removed exposing the granite. Granite has a felsic composition and is more common in recent geologic time in contrast to earth s ultramafic ancient igneous history. Intrusive rocks form from molten material magma that flows and solidifies underground where magma cools slowly.

Igneous rocks are formed from the solidification of molten rock material. Granite which is named for its granular or phaneritic texture has crystals that tend to be easily seen although they are generally small. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form. Granite is an intrusive igneous rock.

Plutonic means that it is magma that does not reach the surface of the earth and so cools very slowly underground. Granite is the most common intrusive plutonic igneous rock. It is a rock that has been used for centuries for many different purposes such as building material. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite.
