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 sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Etymology
From the village of Luxulyan in Cornwall, England, where this variety of granite is found
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Luxullianite and Turbidite Properties
Know all about Luxullianite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Luxullianite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Luxullianite is Granular, Phaneritic whereas that of Turbidite is Mud-rich, Sandy. Luxullianite appears Veined or Pebbled and Turbidite appears Dull and Banded. The luster of Luxullianite is dull to grainy with sporadic parts pearly and vitreous while that of Turbidite is metallic. Luxullianite is available in black, grey, orange, pink, white colors whereas Turbidite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Luxullianite are creating artwork, curling, gemstone, laboratory bench tops, tombstones and that of Turbidite are cemetery markers, creating artwork.
