5 Formation

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.

Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Pyrolite vs Basalt 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 Basalt Reserves. Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. 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 Basalt information and Pyrolite vs Basalt characteristics in the upcoming sections.

More about Pyrolite and Basalt

Here you can know more about Pyrolite and Basalt. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Basalt 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 Basalt includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Pyrolite vs Basalt, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Basalt is available in black, brown, light to dark grey colors. Appearance of Pyrolite is Rough and Shiny and that of Basalt is Dull and Soft. Properties of rock is another aspect for Pyrolite vs Basalt. The hardness of Pyrolite is 5.5-6 and that of Basalt is 6. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite whereas types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Basalt is white to grey. The specific heat capacity of Pyrolite is 1.25 kJ/Kg K and that of Basalt 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.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Basalt is heat resistant, pressure resistant, wear resistant.
