Gneiss vs Pyroxenite

Gneiss 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 Gneiss and Pyroxenite Reserves. Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. 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 Gneiss vs Pyroxenite information and Gneiss vs Pyroxenite characteristics in the upcoming sections.

Gneiss 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. Gneiss vs Pyroxenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gneiss and Properties of Pyroxenite. Learn more about Gneiss vs Pyroxenite in the next section. The interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Pyroxenite include Countertops, Decorative aggregates, Interior decoration and Kitchens. Due to some exceptional properties of Gneiss and Pyroxenite, they have various applications in construction industry. The uses of Gneiss in construction industry include As dimension stone and that of Pyroxenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

Gneiss is available in black, brown, pink, red, white colors whereas, Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. Appearance of Gneiss is Foliated and that of Pyroxenite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Gneiss vs Pyroxenite. Hardness of Gneiss and Pyroxenite is 7. The types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss. 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 Gneiss is white while that of Pyroxenite is white, greenish white or grey. The specific heat capacity of Gneiss is 0.70 kJ/Kg K and that of Pyroxenite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant whereas Pyroxenite is impact resistant, pressure resistant, wear resistant.
