Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

Andesite vs Sandstone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Andesite vs Sandstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Andesite and Properties of Sandstone. Learn more about Andesite vs Sandstone in the next section. The interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Andesite and Sandstone, they have various applications in construction industry. The uses of Andesite in construction industry include Cobblestones, Construction aggregate, For road aggregate and that of Sandstone include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Andesite and Sandstone
Here you can know more about Andesite and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Sandstone 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 Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Sandstone, 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, Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Andesite is Dull and Soft and that of Sandstone is Rough. Properties of rock is another aspect for Andesite vs Sandstone. The hardness of Andesite is 7 and that of Sandstone is 6-7. The types of Andesite are Icelandite whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Andesite and Sandstone is white. The specific heat capacity of Andesite is 2.39 kJ/Kg K and that of Sandstone 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 Sandstone is heat resistant, impact resistant, pressure resistant.
