Definition

Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

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.

The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Tachylite vs Appinite 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 Appinite Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished. 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 Appinite information and Tachylite vs Appinite characteristics in the upcoming sections.

More about Tachylite and Appinite

Here you can know more about Tachylite and Appinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Appinite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Appinite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Tachylite is Glassy and that of Appinite is Dull, Banded and Foilated. Properties of rock is another aspect for Tachylite vs Appinite. The hardness of Tachylite is 5.5 and that of Appinite is 5-6. The types of Tachylite are Volcanic glass whereas types of Appinite are Igneous rock. 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 Appinite is white. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Appinite 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 Appinite is heat resistant, impact resistant.
