Formation

Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

Charnockite vs Diorite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Charnockite and Diorite Reserves. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Charnockite vs Diorite information and Charnockite vs Diorite characteristics in the upcoming sections.

Charnockite vs Diorite 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 Diorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Diorite. Learn more about Charnockite vs Diorite 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 Diorite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Charnockite and Diorite, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Diorite include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate.

More about Charnockite and Diorite

Here you can know more about Charnockite and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Diorite 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 Diorite 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 Charnockite vs Diorite, 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, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Charnockite is Veined or Pebbled and that of Diorite is Shiny. Properties of rock is another aspect for Charnockite vs Diorite. Hardness of Charnockite and Diorite is 6-7. The types of Charnockite are Enderbite whereas types of Diorite are Plagioclase Diorite and Quartz Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite is white while that of Diorite is bluish black. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Diorite 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.Charnockite is heat resistant, wear resistant whereas Diorite is heat resistant, pressure resistant, wear resistant.
