Harzburgite vs Troctolite


Troctolite vs Harzburgite


Definition

Definition
Harzburgite is a plutonic rock of the peridotite group consisting largely of 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

Harzburgite 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 Harzburgite and Troctolite Reserves. Harzburgite is a plutonic rock of the peridotite group consisting largely of 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 Harzburgite vs Troctolite information and Harzburgite vs Troctolite characteristics in the upcoming sections.
