Definition
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.
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
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 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.

More about Luxullianite and Mudstone
Here you can know more about Luxullianite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Luxullianite and Mudstone consists of mineral content and compound content. The mineral content of Luxullianite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, 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 Igneous Rocks. When we have to compare Luxullianite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Luxullianite is available in black, grey, orange, pink, white colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Luxullianite is Veined or Pebbled and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Luxullianite vs Mudstone. The hardness of Luxullianite is 6-7 and that of Mudstone is 2-3. The types of Luxullianite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite 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 Luxullianite and Mudstone is white. The specific heat capacity of Luxullianite is 0.79 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.Luxullianite is heat resistant, wear resistant whereas Mudstone is heat resistant, impact resistant.
