Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Mudstone and Andesite
Here you can know more about Mudstone and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Andesite consists of mineral content and compound content. The mineral content of Mudstone 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 Mudstone vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Mudstone 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 Mudstone is Rough and Dull and that of Andesite is Dull and Soft. Properties of rock is another aspect for Mudstone vs Andesite. The hardness of Mudstone is 2-3 and that of Andesite is 7. The types of Mudstone are Marl, Shale and Argillite 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 Mudstone and Andesite is white. The specific heat capacity of Mudstone is 0.39 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.Mudstone is heat resistant, impact resistant whereas Andesite is heat resistant, pressure resistant, wear resistant.
