Is Granite Mafic Felsic Or Intermediate

Rhyolite is not a mafic rock but a felsic rock high in silicates and similar to granite in composition.

Is granite mafic felsic or intermediate.

Mafic vs felsic mafic and felsic are categories into which igneous rocks are classified. Additionally felsic magmas may have very high gas contents. Mafic felsic and intermediate intrusive rocks. Part i volcanic extrusive rocks.

Intermediate lava has a lower silica content than felsic lava but not as high magnesium or iron levels as found in mafic lava. Intermediate 1472 1832 degrees fahrenheit. Granite is the name given to intrusive felsic rocks whereas rhyolite is the name given to extrusive felsic rocks. It is commonly erupted as passive lava flows due to its low viscosity.

Felsic intermediate mafic which of the following properties increases in the direction of the arrows in the sentence above. Therefore rocks are divided into ultramafic mafic intermediate and felsic. Basalt is an extrusive mafic volcanic rock. Felsic magmas are much more viscous than the intermediate magmas.

Melting temperature potassium content silica content viscosity. Typical intermediate rocks include andesite dacite and trachyandesite among volcanic rocks and diorite and granodiorite among plutonic rocks. Felsic intermediate mafic ultramafic. In igneous petrology an intermediate composition refers to the chemical composition of a rock that has 52 63 wt sio 2 being an intermediate between felsic and mafic compositions.

Due to the color of the minerals forming them the rocks are either light or dark. Gabbro is a mafic rock and has the same chemistry and mineralogy as basalt. What type of magma forms at mid ocean ridges. The lava flow has a medium viscosity as well and once cooled the resulting rock is known as andesite.

This is an order showing increased silica content. For example granite contains around 70 of silica. Diorite is an intermediate rock equivalent to andesite. Intrusive rocks are classified the same way extrusive rocks are according to the relative amounts of feldspars quartz and ferromagnesian minerals.

Basalt andesite ultramafic granite. Granite is a great example of felsic rocks and muscovite quartz and some feldspar are the best examples of felsic minerals. All felsic rocks contain a high percentage of silica.
