Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.
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
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

Granulite 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. Granulite vs Sandstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Sandstone. Learn more about Granulite vs Sandstone in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Granulite and Sandstone, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls 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 Granulite and Sandstone
Here you can know more about Granulite and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Sandstone consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Sandstone, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown 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 Granulite is Veined or Pebbled and that of Sandstone is Rough. Properties of rock is another aspect for Granulite vs Sandstone. Hardness of Granulite and Sandstone is 6-7. The types of Granulite are Not Available 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 Granulite and Sandstone is white. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
