The Most Abundant Element In A Granite Is

Granite is most often formed where oceanic plates dive beneath continental plates in tectonic environments called subduction zones.

The most abundant element in a granite is.

It exists as a major compound of the silicate minerals where it combines with other elements. The principal constituent of granite is feldspar. This mineral composition usually gives granite a red pink gray or white color with dark mineral grains visible throughout the rock. Some granites contain around 10 to 20 parts per million ppm of uranium.

Both plagioclase feldspar and alkali feldspar are usually abundant in it and their relative abundance has provided the basis for granite classifications. In most granite the ratio of the dominant to the subdominant feldspar is less than two. It also exists as a compound in carbonates and phosphates. The resulting magma is less dense than material typically.

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. Popular answers 1 the essential minerals of granite are quartz k feldspar plagioclase of albite oligoclase composition. Oxygen makes up 467 100 ppm parts per million of the earth s crust or 46 6. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals.

Oxygen is the most abundant element in the earth s crust. Granite is a natural source of radiation like most natural stones.
