Definition
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix
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
Borolanites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
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 Borolanite and Sandstone Properties
Know all about Borolanite and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Borolanite belongs to Igneous Rocks while Sandstone belongs to Sedimentary Rocks.Texture of Borolanite is Granular whereas that of Sandstone is Clastic, Granular, Rough. Borolanite appears Banded and Foilated and Sandstone appears Rough. The luster of Borolanite is greasy to dull while that of Sandstone is dull. Borolanite is available in brown, buff, cream, green, grey, pink, white 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 Borolanite are cemetery markers and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
