Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Pyrolite 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.

Charnockite vs Pyrolite 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. Charnockite vs Pyrolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Pyrolite. Learn more about Charnockite vs Pyrolite in the next section. The interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Pyrolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Charnockite and Pyrolite, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Pyrolite include As dimension stone, Cobblestones.
More about Charnockite and Pyrolite
Here you can know more about Charnockite and Pyrolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Pyrolite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Pyrolite, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Pyrolite is available in dark greenish - grey colors. Appearance of Charnockite is Veined or Pebbled and that of Pyrolite is Rough and Shiny. Properties of rock is another aspect for Charnockite vs Pyrolite. The hardness of Charnockite is 6-7 and that of Pyrolite is 5.5-6. The types of Charnockite are Enderbite whereas types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Pyrolite is white. The specific heat capacity of Charnockite is Not Available and that of Pyrolite is 1.25 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Charnockite is heat resistant, wear resistant whereas Pyrolite is heat resistant, pressure resistant, wear resistant.
