Other Minerals That Resemble Granite

Within the field of geology bowen s reaction series is the work of the petrologist norman l.

Other minerals that resemble granite. According to the generally accepted definition a granite must have at least 20. Quartz is a very common mineral in the earth s crust and is almost always well represented in granites. That light background color is punctuated by the darker accessory minerals. The rare and coarse porphyritic large crystals or phenocryst floating in a fine grained groundmass texture is presented by extremely large crystals of k feldspar compared to other minerals.

Second granite always consists of the minerals quartz and feldspar with or without a wide variety of other minerals accessory minerals. It forms from the slow crystallization of magma below earth s surface. Granite that contains large k feldspar grains of spherical shape pink or reddish color is known as porphyritic granite and rapakivi large rounded. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral.

Granite is mined as either crushed stone or dimension stone mainly using open pit mining methods. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Rocks themselves are made of clusters or mixtures of minerals and minerals and rocks affect landform development and form natural resources such as gold tin iron marble and granite. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

Bowen who summarized based on experiments and observations of natural rocks the sequence of crystallization of common silicate minerals from typical basaltic magma undergoing fractional crystallization i e. Crushed limestone is by far the most commonly used crushed rock in the u s representing 70 of total. Crushed granite represents 16 of the total crushed stone produced in the u s and it is the second most utilized crushed stone in the u s. The quartz and feldspar generally give granite a light color ranging from pinkish to white.

Crystallization wherein early formed crystals are removed from the magma by crystal. Unlike other materials granite s cost isn t the best indicator of its quality. Quartz is usually the last mineral to crystallize and fills in the extra space between the other minerals. Learn more about the properties and uses of granite in this article.

The minerals that are found in granite are primarily quartz plagioclase feldspars potassium or k feldspars hornblende and micas.
