Formation
Formation
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
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 Aplite and Dolomite Properties
Know all about Aplite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Aplite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Aplite is Granular, Graphic whereas that of Dolomite is Earthy. Aplite appears Veined or Pebbled and Dolomite appears Glassy or Pearly. The luster of Aplite is dull to pearly to subvitreous while that of Dolomite is vitreous and pearly. Aplite is available in black, grey, orange, pink, white colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones 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).
