Trachyandesite vs Troctolite


Troctolite vs Trachyandesite


Definition

Definition
Trachyandesite is an extrusive igneous rock.   
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   

History

Etymology
From French trachyandésite, trachy + andésite andesite, a lava intermediate in composition between trachyte and andesite   
From German Troklotit, from Greek trōktēs, a marine fish (taken to be trout)

Formation

Formation
Trachyandesite 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.

Trachyandesite 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 Trachyandesite and Troctolite Reserves. Trachyandesite is an extrusive igneous rock.. 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.
