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.
Teschenite 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 vs Teschenite 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 Teschenite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent. 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 Teschenite information and Anorthosite vs Teschenite characteristics in the upcoming sections.

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

More about Anorthosite and Teschenite

Here you can know more about Anorthosite and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Teschenite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Teschenite, 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, Teschenite is available in dark grey to black colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Anorthosite vs Teschenite. The hardness of Anorthosite is 5-6 and that of Teschenite is 7. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Teschenite are Igneous rock. 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 Teschenite is black. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Teschenite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Teschenite is impact resistant, pressure resistant, wear resistant.
