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
  
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

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.
  
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Mudstone vs Quartzite 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 Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Quartzite. Learn more about Mudstone vs Quartzite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Mudstone and Quartzite, 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 Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.
More about Mudstone and Quartzite
Here you can know more about Mudstone and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Quartzite 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 Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Mudstone is Rough and Dull and that of Quartzite is Lustrous. Properties of rock is another aspect for Mudstone vs Quartzite. The hardness of Mudstone is 2-3 and that of Quartzite is 6-7. The types of Mudstone are Marl, Shale and Argillite whereas types of Quartzite 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 Quartzite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
