Is Granite Mafic Or Felsic

Granite is a felsic rock.

Is granite mafic or felsic.

Mafic rocks are dark in color. 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. Mafic rocks derive from basalt protoliths and some volcanogenic sediments. Felsic rocks can be produced by metamorphism of both igneous and sedimentary protoliths e g granite and arkose respectively and are rich in silicon sodium na potassium calcium aluminum and lesser amounts of iron and magnesium.

Felsic refers to silicate minerals magma and rocks which are enriched in the lighter elements such as silicon oxygen aluminium sodium and potassium. All felsic rocks contain a high percentage of silica. It is relating to denoting or containing a group of dark colored mainly ferromagnetic minerals such as pyroxene and olivine.

Rhyolite is not a mafic rock but a felsic rock high in silicates and similar to granite in composition. Mafic vs felsic mafic and felsic are categories into which igneous rocks are classified. For example granite contains around 70 of silica. Felsic rocks are composed of high levels of magma silicate materials and rocks which are also rich in potassium oxygen silicon and sodium.

Common mafic rocks include basalt dolerite and gabbro. The term felsic describes igneous rocks that are relatively rich in the elements that form quartz and feldspar. Common felsic minerals include quartz muscovite hornblende orthoclase and the sodium rich plagioclase feldspars. Granite is a great example of felsic rocks and muscovite quartz and some feldspar are the best examples of felsic minerals.

The most common felsic rock is granite which represents the purified end product of the earth s internal differentiation process. Felsic minerals are usually light in color and have specific gravities less than 3. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Felsic rocks are usually light in color and have specific gravities less than 3.

Felsic magma or lava is higher in viscosity than mafic magma lava. The word mafic comes from ma for magnesium and f for ferrum or the latin for iron. 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.
