5.1 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.

Theralite 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.

Tachylite vs Theralite 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 Theralite Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline. 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 Theralite information and Tachylite vs Theralite characteristics in the upcoming sections.

More about Tachylite and Theralite

Here you can know more about Tachylite and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Theralite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Theralite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Theralite is available in dark grey to black colors. Appearance of Tachylite is Glassy and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Tachylite vs Theralite. The hardness of Tachylite is 5.5 and that of Theralite is 7. The types of Tachylite are Not Available whereas types of Theralite are Teschenite and Essexite. 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 Theralite is white. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Theralite is 0.74 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 Theralite is impact resistant, pressure resistant, wear resistant.
