Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Claystone vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Serpentinite. Learn more about Claystone vs Serpentinite in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Claystone and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Claystone and Serpentinite
Here you can know more about Claystone and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Serpentinite 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 Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Serpentinite, 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, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Claystone is Rough and Dull and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Claystone vs Serpentinite. The hardness of Claystone is 3.5-4 and that of Serpentinite is 3-5. The types of Claystone are Claystone whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
