Troctolite vs Greenschist

Definition

Definition

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
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

Formation

Formation

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.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

Troctolite vs Greenschist 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 Troctolite and Greenschist Reserves. 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. Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism. 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 Troctolite vs Greenschist information and Troctolite vs Greenschist characteristics in the upcoming sections.

Troctolite vs Greenschist 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. Troctolite vs Greenschist characteristics assist us to distinguish and recognize rocks.

More about Troctolite and Greenschist

Here you can know more about Troctolite and Greenschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Troctolite and Greenschist consists of mineral content and compound content. The mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc. You can also check out the list of all Igneous Rocks. When we have to compare Troctolite vs Greenschist, the texture, color and appearance plays an important role in determining the type of rock. Troctolite is available in dark grey to black colors whereas, Greenschist is available in dark greenish - grey, green colors. Appearance of Troctolite is Veined and Shiny and that of Greenschist is Layered and Shiny. Properties of rock is another aspect for Troctolite vs Greenschist. The hardness of Troctolite is 7 and that of Greenschist is 3.5-4. The types of Troctolite are Ultramafic rock whereas types of Greenschist are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Troctolite is black while that of Greenschist is white. The specific heat capacity of Troctolite is 0.84 kJ/Kg K and that of Greenschist 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.Troctolite is impact resistant, pressure resistant, wear resistant whereas Greenschist is impact resistant, pressure resistant, water resistant.
