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
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Sandstone and Boninite Properties
Know all about Sandstone and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Sandstone belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Sandstone is Clastic, Granular, Rough whereas that of Boninite is Aphanitic to Porphyritic. Sandstone appears Rough and Boninite appears Dull and Soft. The luster of Sandstone is dull while that of Boninite is vitreous. Sandstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Boninite is available in bluish - grey, brown, green, grey 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 Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
