Definition

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

Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

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.

Norite 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 Norite 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 Norite Reserves. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. 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 Norite information and Tachylite vs Norite characteristics in the upcoming sections.

More about Tachylite and Norite

Here you can know more about Tachylite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Norite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Norite is available in dark grey to black colors. Appearance of Tachylite is Glassy and that of Norite is Veined and Shiny. Properties of rock is another aspect for Tachylite vs Norite. The hardness of Tachylite is 5.5 and that of Norite is 7. The types of Tachylite are Volcanic glass whereas types of Norite are Ultramafic intrusive 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 Norite is black. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Norite is 0.52 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 Norite is impact resistant, pressure resistant, wear resistant.
