Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
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
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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 Metapelite and Sandstone Properties
Know all about Metapelite and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Metapelite belongs to Metamorphic Rocks while Sandstone belongs to Sedimentary Rocks.Texture of Metapelite is Foliated whereas that of Sandstone is Clastic, Granular, Rough. Metapelite appears Banded and Sandstone appears Rough. The luster of Metapelite is earthy while that of Sandstone is dull. Metapelite is available in dark greenish - grey, green, light green, light greenish grey 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 Metapelite are commemorative tablets, creating artwork and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
