5.1 Formation

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

Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

All about Sandstone and Phonolite Properties

Know all about Sandstone and Phonolite properties here. All properties of rocks are important as they define the type of rock and its application. Sandstone belongs to Sedimentary Rocks while Phonolite belongs to Igneous Rocks.Texture of Sandstone is Clastic, Granular, Rough whereas that of Phonolite is Granular. Sandstone appears Rough and Phonolite appears Banded and Foilated. The luster of Sandstone is dull while that of Phonolite is greasy to dull. 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 Phonolite is available in brown, buff, cream, green, grey, pink, white 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 Phonolite are cemetery markers, creating artwork.
