Charnockite vs Troctolite

Definition

Definition

Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

Formation

Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Troctolite 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 Troctolite 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 Troctolite Reserves. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro. 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 Troctolite information and Charnockite vs Troctolite characteristics in the upcoming sections.

Charnockite vs Troctolite 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 Troctolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Troctolite. Learn more about Charnockite vs Troctolite in the next section.

Due to some exceptional properties of Charnockite and Troctolite, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Troctolite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Charnockite and Troctolite

Here you can know more about Charnockite and Troctolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Troctolite 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 Troctolite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Troctolite, 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, Troctolite is available in dark grey to black colors. Appearance of Charnockite is Veined or Pebbled and that of Troctolite is Veined and Shiny. Properties of rock is another aspect for Charnockite vs Troctolite. The hardness of Charnockite is 6-7 and that of Troctolite is 7. The types of Charnockite are Enderbite whereas types of Troctolite are Ultramafic rock. 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 Troctolite is black. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Troctolite 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 Troctolite is impact resistant, pressure resistant, wear resistant.
