Common Mafic Rocks Are Granit

Felsic magma or lava is higher in viscosity than mafic magma lava.

Common mafic rocks are granit.

Because of their relatively low viscosity mafic lavas may travel great distances and flood the landscapes over which they flow. Many of the lunar rocks brought back to earth through the apollo missions are classified as gabbro with high amounts of olivine and other mafic minerals. Igneous rocks are called intrusive or plutonic when they cool and solidify beneath the surface because they form within the earth cooling occurs slowly such slow cooling allows time for large crystals to form therefore intrusive or plutonic igneous rocks have relatively large mineral crystals that are easy to see. The word mafic comes from ma for magnesium and f for ferrum or the latin for iron.

All are produced by partial melting of the uppermost asthenosphere. Mafic rocks are dark in color. Common mafic rocks include basalt dolerite and gabbro. Strictly speaking granite is an.

Peridotite is a common rock found in the deeper mantle of the earth and exhibits more olivine and less quartz than gabbro although both are considered mafic igneous rocks. 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. The most common felsic rock is granite which represents the purified end product of the earth s internal differentiation process. It is important to note that there are many intermediate steps in the purification process and many intermediate magmas which are produced during the conversion from mafic to felsic.

The most common felsic rock is granite. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Igneous rocks typically consist of approximately 12 major oxides totaling over 99 percent of the rock of the oxides silica sio 2 is usually the most abundant.

Chemical analyses of the most abundant components in rocks usually are presented as oxides of the elements. Felsic rocks are usually light in color and have specific gravities less than 3. Granite is the most common intrusive igneous rock figure 4 4. Felsic and mafic rocks division of igneous rocks on the basis of their silica content.

It is relating to denoting or containing a group of dark colored mainly ferromagnetic minerals such as pyroxene and olivine. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. Mafic lava flows are thin and sometimes called plateau or flood lavas.
