Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Alkali fledspar granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

All about Dolomite and Alkali Feldspar Granite Properties
Know all about Dolomite and Alkali Feldspar Granite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite belongs to Sedimentary Rocks while Alkali Feldspar Granite belongs to Igneous Rocks.Texture of Dolomite is Earthy whereas that of Alkali Feldspar Granite is Phaneritic. Dolomite appears Glassy or Pearly and Alkali Feldspar Granite appears Veined or Pebbled. The luster of Dolomite is vitreous and pearly while that of Alkali Feldspar Granite is dull to grainy with sporadic parts pearly and vitreous. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas Alkali Feldspar Granite is available in black, grey, orange, 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 Alkali Feldspar Granite are curling, gemstone, laboratory bench tops, tombstones.
