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.

Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Peridotite vs Rhyolite 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 Rhyolite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. Rhyolite is a fine-grained igneous rock which is rich in silica. 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 Rhyolite information and Peridotite vs Rhyolite characteristics in the upcoming sections.

More about Peridotite and Rhyolite

Here you can know more about Peridotite and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Rhyolite 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 Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Rhyolite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Rhyolite is available in grey, white, light black colors. Appearance of Peridotite is Rough and Shiny and that of Rhyolite is Banded. Properties of rock is another aspect for Peridotite vs Rhyolite. The hardness of Peridotite is 5.5-6 and that of Rhyolite is 6-7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. 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 Rhyolite is colorless. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Rhyolite is Not Available. 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 Rhyolite is heat resistant, wear resistant.
