Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

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.

Claystone vs Dolomite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Claystone vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Dolomite. Learn more about Claystone vs Dolomite in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Claystone and Dolomite, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Dolomite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Claystone and Dolomite
Here you can know more about Claystone and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Dolomite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. 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. Appearance of Claystone is Rough and Dull and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Claystone vs Dolomite. Hardness of Claystone and Dolomite is 3.5-4. The types of Claystone are Not Available whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Dolomite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Dolomite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
