Definition
Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

Pyroxenite vs Marble 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. Pyroxenite vs Marble characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyroxenite and Properties of Marble. Learn more about Pyroxenite vs Marble in the next section. The interior uses of Pyroxenite include Countertops, Decorative aggregates, Interior decoration and Kitchens whereas the interior uses of Marble include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Pyroxenite and Marble, they have various applications in construction industry. The uses of Pyroxenite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Marble include As dimension stone.
More about Pyroxenite and Marble
Here you can know more about Pyroxenite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyroxenite and Marble 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 Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Pyroxenite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Pyroxenite is Layered, Banded, Veined and Shiny and that of Marble is Veined and Shiny. Properties of rock is another aspect for Pyroxenite vs Marble. The hardness of Pyroxenite is 7 and that of Marble is 3-4. The types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pyroxenite and Marble is white, greenish white or grey. The specific heat capacity of Pyroxenite is 0.84 kJ/Kg K and that of Marble is 0.88 kJ/Kg K. 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 Marble is heat resistant.
