Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Claystone vs Evaporite 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 Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Evaporite. Learn more about Claystone vs Evaporite in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Claystone and Evaporite, 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 Evaporite 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.
More about Claystone and Evaporite
Here you can know more about Claystone and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Evaporite 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 Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Evaporite, 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, Evaporite is available in green, grey, silver, white colors. Appearance of Claystone is Rough and Dull and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Claystone vs Evaporite. The hardness of Claystone is 3.5-4 and that of Evaporite is 2-3. The types of Claystone are Claystone whereas types of Evaporite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Evaporite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Evaporite 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 Evaporite is heat resistant, pressure resistant.
