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.
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

More about Luxullianite and Boninite
Here you can know more about Luxullianite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Luxullianite and Boninite 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 Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Luxullianite vs Boninite, 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, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Luxullianite is Veined or Pebbled and that of Boninite is Dull and Soft. Properties of rock is another aspect for Luxullianite vs Boninite. The hardness of Luxullianite is 6-7 and that of Boninite is 7. The types of Luxullianite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite whereas types of Boninite are Basalt. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Luxullianite and Boninite is white.
