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

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

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