1.1 Definition

Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt

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

5.1 Formation

Pyrolite 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 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.

Pyrolite 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 Pyrolite and Tachylite Reserves. Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt. 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 Pyrolite vs Tachylite information and Pyrolite vs Tachylite characteristics in the upcoming sections.

Pyrolite 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. Pyrolite vs Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyrolite and Properties of Tachylite. Learn more about Pyrolite vs Tachylite in the next section. The interior uses of Pyrolite include Decorative aggregates and Interior decoration whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Pyrolite and Tachylite, they have various applications in construction industry. The uses of Pyrolite in construction industry include As dimension stone, Cobblestones and that of Tachylite include Cutting tool, Knives, Landscaping, Scrapers.

More about Pyrolite and Tachylite

Here you can know more about Pyrolite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Tachylite consists of mineral content and compound content. The mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Igneous Rocks. When we have to compare Pyrolite vs Tachylite, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Tachylite is available in black, dark brown colors. Appearance of Pyrolite is Rough and Shiny and that of Tachylite is Glassy. Properties of rock is another aspect for Pyrolite vs Tachylite. The hardness of Pyrolite is 5.5-6 and that of Tachylite is 5.5. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite 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 Pyrolite is white while that of Tachylite is vermilion. The specific heat capacity of Pyrolite is 1.25 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.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Tachylite is heat resistant, impact resistant, wear resistant.
