Is Granite Felsic Intermediate Or Mafic

Additionally they contain somewhat more gas than do the mafic magmas but not quite as much as the felsic magmas see below.

Is granite felsic intermediate or mafic.

A common mafic rock is basalt. Gabbro and basalt are mafic with an average silica content of 48 percent. Syenite diorite and monzonite are intermediate with an average silica content of 59 percent. 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.

Whereas magma mixing occurs when two ascending bodies of magma join and mix together into a composition that is intermediate to the two original magmas. Felsic intermediate mafic ultramafic. Diorite is the name given to intrusive intermediate rocks whereas andesite is the name given to extrusive intermediate rocks. There is little or no quartz.

All felsic rocks contain a high percentage of silica. Intermediate rocks are roughly even mixtures of felsic minerals mainly plagioclase and mafic minerals mainly hornblende pyroxene and or biotite. This is an order showing increased silica content. More general terms for these rocks are mafic felsic and intermediate.

The term felsic describes igneous rocks that are relatively rich in the elements that form quartz and feldspar. Due to the color of the minerals forming them the rocks are either light or dark. Mafic vs felsic mafic and felsic are categories into which igneous rocks are classified. For example granite contains around 70 of silica.

Part i volcanic extrusive rocks. Mafic rocks have about 50 percent silica and high amounts of iron magnesium and calcium and are dark in color. Basalt is an extrusive mafic volcanic rock. Which of the following is an aphanitic igneous rock.

Intermediate magmas are somewhat more viscous than the mafic magmas. It is commonly erupted as passive lava flows due to its low viscosity. Therefore rocks are divided into ultramafic mafic intermediate and felsic. Granite is a great example of felsic rocks and muscovite quartz and some feldspar are the best examples of felsic minerals.

Felsic rocks are composed of high levels of magma silicate materials and rocks which are also rich in potassium oxygen silicon and sodium. And peridotite is an ultramafic rock with an. Granite is a felsic rock. Felsic rocks are mostly feldspar especially k feldspar at least 10 quartz and less than 15 mafic minerals biotite hornblende.

Gabbro is mafic obsidian is felsic granite is felsic andesite is intermediate. The most common felsic rock is granite which represents the purified end product of the earth s internal differentiation process.
