Andesite vs Evaporite 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 Evaporite Reserves. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution. 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 Evaporite information and Andesite vs Evaporite characteristics in the upcoming sections.

More about Andesite and Evaporite

Here you can know more about Andesite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Evaporite 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 Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Evaporite, 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, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Andesite is Dull and Soft and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Andesite vs Evaporite. The hardness of Andesite is 7 and that of Evaporite is 2-3. The types of Andesite are Icelandite whereas types of Evaporite 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 Evaporite is white. The specific heat capacity of Andesite is 2.39 kJ/Kg K and that of Evaporite is 0.92 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 Evaporite is heat resistant, pressure resistant.
