Archaeological Significance
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.
Blue Granite is an igneous rock which is a variety of Larvikite and is known mainly for the presence of thumbnail-sized crystals of feldspar.

More about Pyroxenite and Blue Granite
Here you can know more about Pyroxenite and Blue Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyroxenite and Blue Granite 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 Blue Granite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Pyroxenite vs Blue Granite, 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, Blue Granite is available in black, brown, light to dark grey, white colors. Appearance of Pyroxenite is Layered, Banded, Veined and Shiny and that of Blue Granite is Shiny. Properties of rock is another aspect for Pyroxenite vs Blue Granite. The hardness of Pyroxenite is 7 and that of Blue Granite is 6-7. The types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites whereas types of Blue Granite are Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pyroxenite and Blue Granite is white, greenish white or grey. The specific heat capacity of Pyroxenite is 0.84 kJ/Kg K and that of Blue Granite is 0.79 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 Blue Granite is heat resistant, impact resistant, pressure resistant.
