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.
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From the village of Luxulyan in Cornwall, England, where this variety of granite is found
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Luxullianite and Conglomerate Properties
Know all about Luxullianite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Luxullianite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Luxullianite is Granular, Phaneritic whereas that of Conglomerate is Clastic. Luxullianite appears Veined or Pebbled and Conglomerate appears Shiny and Rounded. The luster of Luxullianite is dull to grainy with sporadic parts pearly and vitreous while that of Conglomerate is dull. Luxullianite is available in black, grey, orange, pink, white colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Luxullianite are creating artwork, curling, gemstone, laboratory bench tops, tombstones and that of Conglomerate are cemetery markers, in aquifers, tombstones.
