Definition
Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

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.
Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Pyroxenite vs Wehrlite 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 Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyroxenite and Properties of Wehrlite. Learn more about Pyroxenite vs Wehrlite in the next section. The interior uses of Pyroxenite include Countertops, Decorative aggregates, Interior decoration and Kitchens whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Pyroxenite and Wehrlite, 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 Wehrlite include As dimension stone, Cobblestones.
More about Pyroxenite and Wehrlite
Here you can know more about Pyroxenite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyroxenite and Wehrlite 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 Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Pyroxenite vs Wehrlite, 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, Wehrlite is available in dark greenish - grey, green colors. Appearance of Pyroxenite is Layered, Banded, Veined and Shiny and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Pyroxenite vs Wehrlite. The hardness of Pyroxenite is 7 and that of Wehrlite is 5.5-6. The types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites whereas types of Wehrlite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pyroxenite and Wehrlite is white, greenish white or grey. The specific heat capacity of Pyroxenite is Not Available and that of Wehrlite is 0.63 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 Wehrlite is heat resistant, impact resistant, pressure resistant.
