Formation

Formation
Ijolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.   
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.

Ijolite vs Anorthosite 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 Ijolite and Anorthosite Reserves. Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. 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 Ijolite vs Anorthosite information and Ijolite vs Anorthosite characteristics in the upcoming sections.

Ijolite vs Anorthosite 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. Ijolite vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Ijolite and Properties of Anorthosite. Learn more about Ijolite vs Anorthosite in the next section. The interior uses of Ijolite include Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Interior decoration and Kitchens whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Ijolite and Anorthosite, they have various applications in construction industry. The uses of Ijolite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Anorthosite include As dimension stone, Cement manufacture, For road aggregate.

More about Ijolite and Anorthosite

Here you can know more about Ijolite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ijolite and Anorthosite consists of mineral content and compound content. The mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Ijolite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Ijolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Ijolite is Banded and Foilated and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Ijolite vs Anorthosite. The hardness of Ijolite is 5.5-6 and that of Anorthosite is 5-6. The types of Ijolite are Not Available whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite.
