Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
  
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 Basanite and Dolomite Properties
Know all about Basanite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Dolomite is Earthy. Basanite appears Glassy or Pearly and Dolomite appears Glassy or Pearly. The luster of Basanite is waxy and dull while that of Dolomite is vitreous and pearly. Basanite is available in black, brown, green, grey, red, white colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms 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).
