Formation

Formation

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

Anorthosite vs Vogesite 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 Anorthosite and Vogesite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar. 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 Anorthosite vs Vogesite information and Anorthosite vs Vogesite characteristics in the upcoming sections.

Anorthosite vs Vogesite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Anorthosite vs Vogesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Vogesite. Learn more about Anorthosite vs Vogesite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Vogesite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration.
