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

More about Claystone and Trachyandesite
Here you can know more about Claystone and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Trachyandesite 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 Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all . When we have to compare Claystone vs Trachyandesite, 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, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Claystone is Rough and Dull and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Claystone vs Trachyandesite. The hardness of Claystone is 3.5-4 and that of Trachyandesite is 4-5. The types of Claystone are Not Available whereas types of Trachyandesite are Basaltic Trachyandesite. 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 Trachyandesite is light to dark brown. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Trachyandesite is 0.84 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 Trachyandesite is heat resistant, pressure resistant, wear resistant.
