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.
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
