Troctolite vs Scoria


Definition

Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities   
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
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.   
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.

Scoria 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 Scoria and Troctolite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Scoria vs Troctolite information and Scoria vs Troctolite characteristics in the upcoming sections.
