Definition
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle
  
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

Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
  
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

Peridotite 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. Peridotite vs Sandstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Sandstone. Learn more about Peridotite vs Sandstone in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Peridotite and Sandstone, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones 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 Peridotite and Sandstone
Here you can know more about Peridotite and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Sandstone consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene 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 Peridotite vs Sandstone, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey 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 Peridotite is Rough and Shiny and that of Sandstone is Rough. Properties of rock is another aspect for Peridotite vs Sandstone. The hardness of Peridotite is 5.5-6 and that of Sandstone is 6-7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite 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 Peridotite and Sandstone is white. The specific heat capacity of Peridotite is 1.26 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
