Definition
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
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
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.

All about Sandstone and Granulite Properties
Know all about Sandstone and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Sandstone belongs to Sedimentary Rocks while Granulite belongs to Metamorphic Rocks.Texture of Sandstone is Clastic, Granular, Rough whereas that of Granulite is Granoblastic. Sandstone appears Rough and Granulite appears Veined or Pebbled. The luster of Sandstone is dull while that of Granulite is vitreous. Sandstone and Granulite are available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums and that of Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
