Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
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
Norite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

All about Norite and Sandstone Properties
Know all about Norite and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Norite belongs to Igneous Rocks while Sandstone belongs to Sedimentary Rocks.Texture of Norite is Phaneritic whereas that of Sandstone is Clastic, Granular, Rough. Norite appears Veined and Shiny and Sandstone appears Rough. The luster of Norite is while that of Sandstone is dull. Norite is available in dark grey to black colors whereas Sandstone is 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 Norite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
