Caracteristics Of A Granite Rock Felsic

Granites can be predominantly white pink or gray in color depending on their mineralogy.

Caracteristics of a granite rock felsic.

For countertops the granite blocks are cut into granite slabs. Granite is a common type of granular and phaneritic felsic intrusive igneous rock. 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. Because they are made of lighter elements they tend to be more.

Felsic refers to silicate minerals magma and rocks which are enriched in the lighter elements such as silicon oxygen aluminium sodium and potassium. In reference to the coarse grained structure of such a holocrystalline rock the word granite comes from the latin granum a grain. Felsic rocks are igneous rocks that are rich in feldspar and silicon. Granite is an igneous rock that can be found in either the earth s crust or above ground.

Felsic rock felsic rocks include dacite rhyolite their intrusive equivalents of granodiorite and granite and a variety of less common rock types with higher or lower contents of na and k. Granites depending on their mineralogy can be predominantly white pink or gray in colour. From this rock stone is cut for building purposes. Applying this definition requires the mineral.

Granite is made up of mostly quartz and feldspar. The word felsic was made up from parts of those words. Granite is a plutonic rock in which quartz makes up between 10 and 50 percent of the felsic components and alkali feldspar accounts for 65 to 90 percent of the total feldspar content. The most common felsic rock is granite.

Felsic magma or lava is higher in viscosity than mafic magma lava. Felsic rocks are usually light in color and have specific gravities less than 3. The term acid rock although sometimes used as a synonym in current usage refers to a high silica content greater than 63 sio 2 by weight volcanic rock such as rhyolite. On the opposite side of the rock spectrum are the iron and magnesium rich mafic and ultramafic minerals and rocks.
