Andesite vs Granulite 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 Andesite and Granulite Reserves. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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 Andesite vs Granulite information and Andesite vs Granulite characteristics in the upcoming sections.

More about Andesite and Granulite

Here you can know more about Andesite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Granulite consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Granulite is available in black, brown colors. Appearance of Andesite is Dull and Soft and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Andesite vs Granulite. The hardness of Andesite is 7 and that of Granulite is 6-7. The types of Andesite are Icelandite whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Andesite and Granulite is white. The specific heat capacity of Andesite is 2.39 kJ/Kg K and that of Granulite is 0.14 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Andesite is heat resistant, pressure resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
