Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.   
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

Granulite vs Pyroxenite 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 Granulite and Pyroxenite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine. 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 Granulite vs Pyroxenite information and Granulite vs Pyroxenite characteristics in the upcoming sections.

Granulite vs Pyroxenite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Granulite vs Pyroxenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Pyroxenite. Learn more about Granulite vs Pyroxenite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Pyroxenite include Countertops, Decorative aggregates, Interior decoration and Kitchens. Due to some exceptional properties of Granulite and Pyroxenite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Pyroxenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Granulite and Pyroxenite

Here you can know more about Granulite and Pyroxenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Pyroxenite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Pyroxenite includes Amphibole, Augite, Bronzite, Chromite, Diopside, Enstatite, Garnet, Hornblende, Hypersthene, Magnetite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Pyroxenite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. Appearance of Granulite is Veined or Pebbled and that of Pyroxenite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Granulite vs Pyroxenite. The hardness of Granulite is 6-7 and that of Pyroxenite is 7. The types of Granulite are Not Available whereas types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite is white while that of Pyroxenite is white, greenish white or grey. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Pyroxenite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Pyroxenite is impact resistant, pressure resistant, wear resistant.
