5.1 Formation

Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

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

Pyroxenite 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 Pyroxenite and Rhyolite Reserves. Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine. 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 Pyroxenite vs Rhyolite information and Pyroxenite vs Rhyolite characteristics in the upcoming sections.

More about Pyroxenite and Rhyolite

Here you can know more about Pyroxenite and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyroxenite and Rhyolite consists of mineral content and compound content. The mineral content of Pyroxenite includes Amphibole, Augite, Bronzite, Chromite, Diopside, Enstatite, Garnet, Hornblende, Hypersthene, Magnetite, 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 Pyroxenite vs Rhyolite, the texture, color and appearance plays an important role in determining the type of rock. Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors whereas, Rhyolite is available in grey, white, light black colors. Appearance of Pyroxenite is Layered, Banded, Veined and Shiny and that of Rhyolite is Banded. Properties of rock is another aspect for Pyroxenite vs Rhyolite. The hardness of Pyroxenite is 7 and that of Rhyolite is 6-7. The types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites 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 Pyroxenite is white, greenish white or grey while that of Rhyolite is colorless. The specific heat capacity of Pyroxenite is Not Available 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.Pyroxenite is impact resistant, pressure resistant, wear resistant whereas Rhyolite is heat resistant, wear resistant.
