Formation

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.

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

Epidosite vs Basanite 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 Epidosite and Basanite Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone. 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 Epidosite vs Basanite information and Epidosite vs Basanite characteristics in the upcoming sections.

More about Epidosite and Basanite

Here you can know more about Epidosite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Basanite consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Basanite , the texture, color and appearance plays an important role in determining the type of rock. Epidosite is available in black, brown, light to dark grey colors whereas, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Epidosite is Dull and Soft and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Epidosite vs Basanite . The hardness of Epidosite is 6 and that of Basanite is 7. The types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Epidosite is white to grey while that of Basanite is white. The specific heat capacity of Epidosite is 0.84 kJ/Kg K and that of Basanite is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Epidosite is heat resistant, pressure resistant, wear resistant whereas Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
