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
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

All about Sandstone and Phyllite Properties
Know all about Sandstone and Phyllite properties here. All properties of rocks are important as they define the type of rock and its application. Sandstone belongs to Sedimentary Rocks while Phyllite belongs to Metamorphic Rocks.Texture of Sandstone is Clastic, Granular, Rough whereas that of Phyllite is Phyllitic Sheen, Slaty. Sandstone appears Rough and Phyllite appears Crinkled or Wavy. The luster of Sandstone is dull while that of Phyllite is phyllitic. 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 Phyllite is available in black to grey, light greenish 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 Phyllite are cemetery markers, commemorative tablets, creating artwork, writing slates.
