Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Claystone vs Epidosite 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 Epidosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Epidosite. Learn more about Claystone vs Epidosite in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration. Due to some exceptional properties of Claystone and Epidosite, 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 Epidosite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Claystone and Epidosite
Here you can know more about Claystone and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Epidosite 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 Epidosite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Epidosite, 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, Epidosite is available in black, brown, light to dark grey colors. Appearance of Claystone is Rough and Dull and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Claystone vs Epidosite. The hardness of Claystone is 3.5-4 and that of Epidosite is 6. The types of Claystone are Not Available whereas types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Epidosite is white to grey. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Epidosite is Not Available. 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 Epidosite is heat resistant, pressure resistant, wear resistant.
