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
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

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.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Metapelite and Dolomite Properties
Know all about Metapelite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Metapelite belongs to Metamorphic Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Metapelite is Foliated whereas that of Dolomite is Earthy. Metapelite appears Banded and Dolomite appears Glassy or Pearly. The luster of Metapelite is earthy while that of Dolomite is vitreous and pearly. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Metapelite are commemorative tablets, creating artwork and that of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
