Troctolite vs Pseudotachylite

1 Definition
1.1 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
Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.

From German Troklotit, from Greek trōktēs, a marine fish (taken to be trout)
From pseudo- +‎ tachylite, a glassy rock generated by frictional heat within faults.

5 Formation
5.1 Formation
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Troctolite vs Pseudotachylite 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 Pseudotachylite 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. Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.. 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 Pseudotachylite information and Troctolite vs Pseudotachylite characteristics in the upcoming sections.

Troctolite vs Pseudotachylite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others.
