Basanite  and Dolomite


Dolomite and Basanite 


Definition

Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone   
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation

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).
