Basaltic Trachyandesite vs Tachylite


Definition

Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt  
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

Formation

Formation
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.  
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Tachylite vs Basaltic Trachyandesite 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 Tachylite and Basaltic Trachyandesite Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface. 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 Tachylite vs Basaltic Trachyandesite information and Tachylite vs Basaltic Trachyandesite characteristics in the upcoming sections.

More about Tachylite and Basaltic Trachyandesite

Here you can know more about Tachylite and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Basaltic Trachyandesite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Basaltic Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Tachylite is Glassy and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Tachylite vs Basaltic Trachyandesite. The hardness of Tachylite is 5.5 and that of Basaltic Trachyandesite is 6. The types of Tachylite are Volcanic glass whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tachylite is vermilion while that of Basaltic Trachyandesite is white to grey. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Basaltic Trachyandesite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tachylite is heat resistant, impact resistant, wear resistant whereas Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant.
