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
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures

Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

All about Sandstone and Whiteschist Properties
Know all about Sandstone and Whiteschist properties here. All properties of rocks are important as they define the type of rock and its application. Sandstone belongs to Sedimentary Rocks while Whiteschist belongs to Metamorphic Rocks.Texture of Sandstone is Clastic, Granular, Rough whereas that of Whiteschist is Foliated. Sandstone appears Rough and Whiteschist appears Banded and Foilated. The luster of Sandstone is dull while that of Whiteschist is subvitreous to dull. Sandstone and Whiteschist are 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 Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums and that of Whiteschist are creating artwork, gemstone, jewelry, production of lime.
