Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation
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.
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 Whiteschist and Dolomite Properties
Know all about Whiteschist and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Whiteschist belongs to Metamorphic Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Whiteschist is Foliated whereas that of Dolomite is Earthy. Whiteschist appears Banded and Foilated and Dolomite appears Glassy or Pearly. The luster of Whiteschist is subvitreous to dull while that of Dolomite is vitreous and pearly. Whiteschist is available in colourless, green, grey, white colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Whiteschist are creating artwork, gemstone, jewelry, production of lime 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).
