Archaeological Significance
Formation
Monzogranite 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.
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

Monzogranite 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. Monzogranite vs Pyroxenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Monzogranite and Properties of Pyroxenite. Learn more about Monzogranite vs Pyroxenite in the next section. The interior uses of Monzogranite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, 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 Monzogranite and Pyroxenite, they have various applications in construction industry. The uses of Monzogranite 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.
More about Monzogranite and Pyroxenite
Here you can know more about Monzogranite and Pyroxenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzogranite and Pyroxenite consists of mineral content and compound content. The mineral content of Monzogranite includes Apatite, Biotite, Hornblende, Microcline, Perthite, Plagioclase, Quartz, Titanite, Zircon 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 Igneous Rocks. When we have to compare Monzogranite vs Pyroxenite, the texture, color and appearance plays an important role in determining the type of rock. Monzogranite is available in black, grey, orange, pink, white colors whereas, Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. Appearance of Monzogranite is Veined or Pebbled and that of Pyroxenite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Monzogranite vs Pyroxenite. The hardness of Monzogranite is 6-7 and that of Pyroxenite is 7. The types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite 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 Monzogranite is white while that of Pyroxenite is white, greenish white or grey. The specific heat capacity of Monzogranite is 0.79 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.Monzogranite is heat resistant, wear resistant whereas Pyroxenite is impact resistant, pressure resistant, wear resistant.
