5.1 Formation

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

All about Dolomite and Sandstone Properties

Know all about Dolomite and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite and Sandstone belong to Sedimentary Rocks.Texture of Dolomite is Earthy whereas that of Sandstone is Clastic, Granular, Rough. Dolomite appears Glassy or Pearly and Sandstone appears Rough. The luster of Dolomite is vitreous and pearly while that of Sandstone is dull. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses 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) and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
