Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.
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

Archaeological Significance
Formation
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 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 vs Mudstone 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. Granulite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Mudstone. Learn more about Granulite vs Mudstone in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Granulite and Mudstone, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Granulite and Mudstone
Here you can know more about Granulite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Mudstone consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Granulite vs Mudstone. The hardness of Granulite is 6-7 and that of Mudstone is 2-3. The types of Granulite are Metamorphic rock whereas types of Mudstone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Mudstone is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Mudstone is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Mudstone is heat resistant, impact resistant.
