5 Formation
5.1 Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
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.

Andesite 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 Andesite and Tachylite Reserves. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. 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 Andesite vs Tachylite information and Andesite vs Tachylite characteristics in the upcoming sections.

Andesite 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. Andesite vs Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Andesite and Properties of Tachylite. Learn more about Andesite vs Tachylite in the next section. The interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Andesite and Tachylite, they have various applications in construction industry. The uses of Andesite in construction industry include Cobblestones, Construction aggregate, For road aggregate and that of Tachylite include Cutting tool, Knives, Landscaping, Scrapers.

More about Andesite and Tachylite

Here you can know more about Andesite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Tachylite consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Tachylite, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Tachylite is available in black, dark brown colors. Appearance of Andesite is Dull and Soft and that of Tachylite is Glassy. Properties of rock is another aspect for Andesite vs Tachylite. The hardness of Andesite is 7 and that of Tachylite is 5.5. The types of Andesite are Icelandite 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 Andesite is white while that of Tachylite is vermilion. The specific heat capacity of Andesite is 2.39 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.Andesite is heat resistant, pressure resistant, wear resistant whereas Tachylite is heat resistant, impact resistant, wear resistant.
