Troctolite vs Norite


Definition

Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine  
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
Norite 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.

Norite 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 Norite and Troctolite Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. 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 Norite vs Troctolite information and Norite vs Troctolite characteristics in the upcoming sections.

Norite 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. Norite vs Troctolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Norite and Properties of Troctolite. Learn more about Norite vs Troctolite in the next section. The interior uses of Norite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Troctolite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Norite and Troctolite, they have various applications in construction industry. The uses of Norite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Troctolite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Norite and Troctolite

Here you can know more about Norite and Troctolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Troctolite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene 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 Norite vs Troctolite, the texture, color and appearance plays an important role in determining the type of rock. Norite is available in dark grey to black colors whereas, Troctolite is available in dark grey to black colors. Appearance of Norite is Veined and Shiny and that of Troctolite is Veined and Shiny. Properties of rock is another aspect for Norite vs Troctolite. Hardness of Norite and Troctolite is 7. The types of Norite are Ultramafic intrusive rock 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 Norite and Troctolite is black. The specific heat capacity of Norite is 0.52 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.Norite is impact resistant, pressure resistant, wear resistant whereas Troctolite is impact resistant, pressure resistant, wear resistant.
