5 Formation

5.1 Formation

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

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.

Peridotite 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 Peridotite and Theralite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Peridotite vs Theralite information and Peridotite vs Theralite characteristics in the upcoming sections.

More about Peridotite and Theralite

Here you can know more about Peridotite and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Theralite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene 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 Peridotite vs Theralite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Theralite is available in dark grey to black colors. Appearance of Peridotite is Rough and Shiny and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Peridotite vs Theralite. The hardness of Peridotite is 5.5-6 and that of Theralite is 7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite 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 Peridotite and Theralite is white. The specific heat capacity of Peridotite is 1.26 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Theralite is impact resistant, pressure resistant, wear resistant.
