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.

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

Peridotite vs Tonalite 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 Tonalite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. 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 Tonalite information and Peridotite vs Tonalite characteristics in the upcoming sections.

More about Peridotite and Tonalite

Here you can know more about Peridotite and Tonalite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Tonalite 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 Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Tonalite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Tonalite is available in black, brown, light to dark grey, white colors. Appearance of Peridotite is Rough and Shiny and that of Tonalite is Banded and Foilated. Properties of rock is another aspect for Peridotite vs Tonalite. The hardness of Peridotite is 5.5-6 and that of Tonalite is 6-7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Tonalite are Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite is white while that of Tonalite is bluish black. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Tonalite is 0.92 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 Tonalite is heat resistant, pressure resistant, water resistant.
