Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
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

Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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.

All about Limestone and Metapelite Properties
Know all about Limestone and Metapelite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Metapelite belongs to Metamorphic Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Metapelite is Foliated. Limestone appears Rough and Banded and Metapelite appears Banded. The luster of Limestone is dull to pearly while that of Metapelite is earthy. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. The commercial uses of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper and that of Metapelite are commemorative tablets, creating artwork.
