Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Litchfieldite is a rare igneous rock which is coarse-grained, foliated and a variety of nepheline syenite, sometimes also called as nepheline syenite gneiss or gneissic nepeheline syenite

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Litchfieldite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Dolomite and Litchfieldite Properties
Know all about Dolomite and Litchfieldite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite belongs to Sedimentary Rocks while Litchfieldite belongs to Igneous Rocks.Texture of Dolomite is Earthy whereas that of Litchfieldite is Granular. Dolomite appears Glassy or Pearly and Litchfieldite appears Banded and Foilated. The luster of Dolomite is vitreous and pearly while that of Litchfieldite is greasy to dull. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas Litchfieldite is available in brown, buff, cream, 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 Litchfieldite are creating artwork.
