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
Luxullianite is a rare type of granite, known for presence of clusters of radially arranged acicular tourmaline crystals which are enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica.

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.
Luxullianite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture. It is found in large plutons on the continents, i.e. in areas where the Earth's crust has been deeply eroded.

Mudstone vs Luxullianite 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 Luxullianite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Luxullianite. Learn more about Mudstone vs Luxullianite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Luxullianite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Mudstone and Luxullianite, 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 Luxullianite include As dimension stone.
More about Mudstone and Luxullianite
Here you can know more about Mudstone and Luxullianite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Luxullianite 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 Luxullianite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Luxullianite, 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, Luxullianite is available in black, grey, orange, pink, white colors. Appearance of Mudstone is Rough and Dull and that of Luxullianite is Veined or Pebbled. Properties of rock is another aspect for Mudstone vs Luxullianite. The hardness of Mudstone is 2-3 and that of Luxullianite is 6-7. The types of Mudstone are Marl, Shale and Argillite whereas types of Luxullianite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Luxullianite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Luxullianite is 0.79 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 Luxullianite is heat resistant, wear resistant.
