Basaltic Trachyandesite vs Epidosite

Epidosite

Add ⊕

Definition

Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt

Formation

Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Epidosite 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.

Basaltic Trachyandesite vs Epidosite 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 Basaltic Trachyandesite and Epidosite Reserves. Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. 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.
