5.1 Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
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.

Migmatite 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 Migmatite and Anorthosite Reserves. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. 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 Migmatite vs Anorthosite information and Migmatite vs Anorthosite characteristics in the upcoming sections.

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

More about Migmatite and Anorthosite

Here you can know more about Migmatite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Anorthosite consists of mineral content and compound content. The mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Migmatite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Migmatite vs Anorthosite.
