Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Claystone and Andesite
Here you can know more about Claystone and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Andesite 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Claystone is Rough and Dull and that of Andesite is Dull and Soft. Properties of rock is another aspect for Claystone vs Andesite. The hardness of Claystone is 3.5-4 and that of Andesite is 7. The types of Claystone are Not Available whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Andesite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
