The Most Abundant Element In A Granite Is

Oxygen is the most abundant element in the earth s crust.
The most abundant element in a granite is. It forms from the slow crystallization of magma below earth s surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals. The principal constituent of granite is feldspar. Oxygen makes up 467 100 ppm parts per million of the earth s crust or 46 6.
In most granite the ratio of the dominant to the subdominant feldspar is less than two. The common accessory minerals include biotite zircon apatite sphene. This mineral composition usually gives granite a red pink gray or white color with dark mineral grains visible throughout the rock. In these zones the input of water rich oceanic crust causes partial melting at the base of the crust about 25 to 30 miles below the earth s surface.
Both plagioclase feldspar and alkali feldspar are usually abundant in it and their relative abundance has provided the basis for granite classifications. Granite is a natural source of radiation like most natural stones. It also exists as a compound in carbonates and phosphates. Granite is most often formed where oceanic plates dive beneath continental plates in tectonic environments called subduction zones.
