Formation

Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.   
Luxullianite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture. It is found in large plutons on the continents, i.e. in areas where the Earth's crust has been deeply eroded.

Dunite vs Luxullianite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Dunite and Luxullianite Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Luxullianite is a rare type of granite, known for presence of clusters of radially arranged acicular tourmaline crystals which are enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Dunite vs Luxullianite information and Dunite vs Luxullianite characteristics in the upcoming sections.
