5 Formation

5.1 Formation

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

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 Siltstone and Dolomite Properties

Know all about Siltstone and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Siltstone and Dolomite belong to Sedimentary Rocks.Texture of Siltstone is Clastic whereas that of Dolomite is Earthy. Siltstone appears Rough and Dolomite appears Glassy or Pearly. The luster of Siltstone is dull while that of Dolomite is vitreous and pearly. Siltstone is available in brown, red, reddish brown colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Siltstone are raw material for the manufacture of mortar, soil conditioner 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).
