Is Basalt Granite

The magma was trapped deep in the crust took a long time to cool down and crystallize into solid rock.

Is basalt granite.

Under this definition gabbro basalt pegmatite schist gneiss syenite monzonite anorthosite granodiorite diabase diorite and many other rocks will be called granite granite counter tops. Strictly speaking granite is an. Magma breaks through the crust of the earth and erupts on the surface. Basalt is mafic while granite is felsic.

Granite counter tops in a new kitchen. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks. Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.

Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Basaltic crust is dark and thin and heavy while granite is light and accumulates into continent sized rafts which bob about like corks in this sea of basalt. This shield volcano is composed of basalt and has enormous calderas at the summit. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of earth.

Basalt and granite are two types of igneous rocks. As it turns out most of the ocean floor is basalt and most of the continents are granite. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock. Granite has a felsic composition and is more common in recent geologic time in contrast to earth s ultramafic ancient igneous history.

The difference between basalt and gabbro is that basalt is a fine grained rock while gabbro is a coarse grained 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.
