Troctolite vs Hornblendite


Hornblendite vs Troctolite


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  
Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock

Troctolite vs Hornblendite 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 Hornblendite 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. Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock. 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 Hornblendite information and Troctolite vs Hornblendite characteristics in the upcoming sections.

More about Troctolite and Hornblendite

Here you can know more about Troctolite and Hornblendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Troctolite and Hornblendite consists of mineral content and compound content. The mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Troctolite vs Hornblendite, 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, Hornblendite is available in black, brown, green, grey colors. Appearance of Troctolite is Veined and Shiny and that of Hornblendite is Foliated. Properties of rock is another aspect for Troctolite vs Hornblendite. The hardness of Troctolite is 7 and that of Hornblendite is 6-7. The types of Troctolite are Ultramafic rock whereas types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite. 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 Hornblendite is white to grey. The specific heat capacity of Troctolite is 0.84 kJ/Kg K and that of Hornblendite 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 Hornblendite is heat resistant, pressure resistant, wear resistant.
