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.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Mudstone vs Granulite 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. Mudstone vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Granulite. Learn more about Mudstone vs Granulite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Mudstone and Granulite, they have various applications in construction industry. 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 Granulite include As dimension stone, Building houses or walls.
More about Mudstone and Granulite
Here you can know more about Mudstone and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Granulite 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 Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Mudstone is Rough and Dull and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Mudstone vs Granulite. The hardness of Mudstone is 2-3 and that of Granulite is 6-7. The types of Mudstone are Marl, Shale and Argillite whereas types of Granulite 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 Granulite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
