Sandstone vs Andesite 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 Sandstone and Andesite Reserves. Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. 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 Sandstone vs Andesite information and Sandstone vs Andesite characteristics in the upcoming sections.

More about Sandstone and Andesite

Here you can know more about Sandstone and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sandstone and Andesite consists of mineral content and compound content. The mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Sandstone vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Sandstone is Rough and that of Andesite is Dull and Soft. Properties of rock is another aspect for Sandstone vs Andesite. The hardness of Sandstone is 6-7 and that of Andesite is 7. The types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Sandstone and Andesite is white. The specific heat capacity of Sandstone is 0.92 kJ/Kg K and that of Andesite is 2.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Sandstone is heat resistant, impact resistant, pressure resistant whereas Andesite is heat resistant, pressure resistant, wear resistant.
