Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
  
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 Hawaiite and Dolomite Properties
Know all about Hawaiite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Hawaiite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Dolomite is Earthy. Hawaiite appears Dull and Soft and Dolomite appears Glassy or Pearly. The luster of Hawaiite is not available while that of Dolomite is vitreous and pearly. Hawaiite is available in black, brown, light to dark grey colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Hawaiite are creating artwork, sea defence 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).
