Is Granite Mafic Or Felsic

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

Common mafic rocks include basalt dolerite and gabbro.

Is granite mafic or felsic.

The most common felsic rock is granite which represents the purified end product of the earth s internal differentiation process. 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. It is relating to denoting or containing a group of dark colored mainly ferromagnetic minerals such as pyroxene and olivine.

On the opposite side of the rock spectrum are the iron and magnesium rich mafic and ultramafic minerals. All felsic rocks contain a high percentage of silica. Felsic refers to silicate minerals magma and rocks which are enriched in the lighter elements such as silicon oxygen aluminium sodium and potassium. Rhyolite is not a mafic rock but a felsic rock high in silicates and similar to granite in composition.

Felsic minerals are usually light in color and have specific gravities less than 3. Granite is a felsic rock. Load more geology mining igneous rock volcanoes oceans and seas the difference between. 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.

Mafic vs felsic mafic and felsic are categories into which igneous rocks are classified. Felsic rocks are composed of high levels of magma silicate materials and rocks which are also rich in potassium oxygen silicon and sodium. 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 rocks 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. Mafic rocks are dark in color. The most common felsic rock is granite. For example granite contains around 70 of silica.

Common felsic minerals include quartz muscovite hornblende orthoclase and the sodium rich plagioclase feldspars. Mafic rocks derive from basalt protoliths and some volcanogenic sediments. The term felsic describes igneous rocks that are relatively rich in the elements that form quartz and feldspar.
