5 Formation

5.1 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.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Anorthosite vs Metapelite 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 Metapelite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone. 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 Metapelite information and Anorthosite vs Metapelite characteristics in the upcoming sections.

More about Anorthosite and Metapelite

Here you can know more about Anorthosite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Metapelite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Metapelite is Banded. Properties of rock is another aspect for Anorthosite vs Metapelite. Hardness of Anorthosite and Metapelite is 5-6. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Metapelite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite is white while that of Metapelite is unknown. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Metapelite is 0.72 kJ/Kg K.
