Formation
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 is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Epidosite 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. Epidosite vs Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Epidosite and Properties of Claystone. Learn more about Epidosite vs Claystone in the next section. The interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels 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 Epidosite and Claystone, they have various applications in construction industry. The uses of Epidosite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone 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 Epidosite and Claystone
Here you can know more about Epidosite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Claystone consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, 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 Epidosite vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Epidosite is available in black, brown, light to dark grey colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Epidosite is Dull and Soft and that of Claystone is Rough and Dull. Properties of rock is another aspect for Epidosite vs Claystone. The hardness of Epidosite is 6 and that of Claystone is 3.5-4. The types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Claystone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Epidosite is white to grey while that of Claystone is white. The specific heat capacity of Epidosite is Not Available 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.Epidosite is heat resistant, pressure resistant, wear resistant whereas Claystone is heat resistant, impact resistant.
