5 Formation

5.1 Formation

Teschenite 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.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

Teschenite vs Dunite 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 Teschenite and Dunite Reserves. Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. 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 Teschenite vs Dunite information and Teschenite vs Dunite characteristics in the upcoming sections.
