Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

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.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

The uses of Mudstone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Appinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Mudstone and Appinite
Here you can know more about Mudstone and Appinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Appinite 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 Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Appinite, 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, Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Mudstone is Rough and Dull and that of Appinite is Dull, Banded and Foilated. Properties of rock is another aspect for Mudstone vs Appinite. The hardness of Mudstone is 2-3 and that of Appinite is 5-6. The types of Mudstone are Marl, Shale and Argillite whereas types of Appinite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Appinite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Appinite is Not Available. 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 Appinite is heat resistant, impact resistant.
