Definition
Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Archaeological Significance
Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Dunite vs Claystone 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. Dunite vs Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dunite and Properties of Claystone. Learn more about Dunite vs Claystone in the next section. The interior uses of Dunite include Decorative aggregates and Interior decoration whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Dunite and Claystone, they have various applications in construction industry. The uses of Dunite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Claystone 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.
More about Dunite and Claystone
Here you can know more about Dunite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Claystone consists of mineral content and compound content. The mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Dunite is Rough and Shiny and that of Claystone is Rough and Dull. Properties of rock is another aspect for Dunite vs Claystone. Hardness of Dunite and Claystone is 3.5-4. The types of Dunite are Dunite whereas types of Claystone are Claystone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite and Claystone is white. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Claystone 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.Dunite is heat resistant, pressure resistant, wear resistant whereas Claystone is heat resistant, impact resistant.
