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
  
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
  
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

All about Sandstone and Gabbro Properties
Know all about Sandstone and Gabbro properties here. All properties of rocks are important as they define the type of rock and its application. Sandstone belongs to Sedimentary Rocks while Gabbro belongs to Igneous Rocks.Texture of Sandstone is Clastic, Granular, Rough whereas that of Gabbro is Phaneritic. Sandstone appears Rough and Gabbro appears Veined and Shiny. The luster of Sandstone is dull while that of Gabbro is not available. 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 Gabbro is available in dark grey to black 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 Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
