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.
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Luxullianite and Serpentinite
Here you can know more about Luxullianite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Luxullianite and Serpentinite 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 Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Luxullianite vs Serpentinite, 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, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Luxullianite is Veined or Pebbled and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Luxullianite vs Serpentinite. The hardness of Luxullianite is 6-7 and that of Serpentinite is 3-5. The types of Luxullianite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Luxullianite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Luxullianite is 0.79 kJ/Kg K and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
