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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Pyroxenite vs Talc carbonate 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 Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyroxenite and Properties of Talc carbonate. Learn more about Pyroxenite vs Talc carbonate in the next section. The interior uses of Pyroxenite include Countertops, Decorative aggregates, Interior decoration and Kitchens whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Pyroxenite and Talc carbonate, 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 Talc carbonate include Source of calcium.
More about Pyroxenite and Talc carbonate
Here you can know more about Pyroxenite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyroxenite and Talc carbonate 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 Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Igneous Rocks. When we have to compare Pyroxenite vs Talc carbonate, 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, Talc carbonate is available in colourless, grey, white colors. Appearance of Pyroxenite is Layered, Banded, Veined and Shiny and that of Talc carbonate is Soft. Properties of rock is another aspect for Pyroxenite vs Talc carbonate. The hardness of Pyroxenite is 7 and that of Talc carbonate is 1-2. The types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites whereas types of Talc carbonate 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 Talc carbonate is white, greenish white or grey. The specific heat capacity of Pyroxenite is Not Available and that of Talc carbonate is 0.92 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 Talc carbonate is heat resistant, wear resistant.
