5.1 Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

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 Claystone and Dolomite Properties

Know all about Claystone and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Claystone and Dolomite belong to Sedimentary Rocks.Texture of Claystone is Clastic whereas that of Dolomite is Earthy. Claystone appears Rough and Dull and Dolomite appears Glassy or Pearly. The luster of Claystone is dull while that of Dolomite is vitreous and pearly. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Claystone are pottery 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).
