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.
Tachylite 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 Tachylite 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 Tachylite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. 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 Tachylite information and Anorthosite vs Tachylite characteristics in the upcoming sections.

Anorthosite vs Tachylite 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 Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Tachylite. Learn more about Anorthosite vs Tachylite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Anorthosite and Tachylite, 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 Tachylite include Cutting tool, Knives, Landscaping, Scrapers.

More about Anorthosite and Tachylite

Here you can know more about Anorthosite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Tachylite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Tachylite, 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, Tachylite is available in black, dark brown colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Tachylite is Glassy. Properties of rock is another aspect for Anorthosite vs Tachylite. The hardness of Anorthosite is 5-6 and that of Tachylite is 5.5. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Tachylite 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 Tachylite is vermilion. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Tachylite is 0.56 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 Tachylite is heat resistant, impact resistant, wear resistant.
