Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Charnockite vs Peridotite 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 Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Peridotite. Learn more about Charnockite vs Peridotite 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 Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Charnockite and Peridotite, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Peridotite include As dimension stone, Cobblestones.
More about Charnockite and Peridotite
Here you can know more about Charnockite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Peridotite 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 Peridotite 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 Peridotite, 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, Peridotite is available in dark greenish - grey colors. Appearance of Charnockite is Veined or Pebbled and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Charnockite vs Peridotite. The hardness of Charnockite is 6-7 and that of Peridotite is 5.5-6. The types of Charnockite are Enderbite whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Peridotite is white. The specific heat capacity of Charnockite is Not Available and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
