Chalk and Luxullianite

1 Definition
1.1 Definition
Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers
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.

5 Formation
5.1 Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
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.

All about Chalk and Luxullianite Properties

Know all about Chalk and Luxullianite properties here. All properties of rocks are important as they define the type of rock and its application. Chalk belongs to Sedimentary Rocks while Luxullianite belongs to Igneous Rocks.Texture of Chalk is Clastic or Non-Clastic whereas that of Luxullianite is Granular, Phaneritic. Chalk appears Soft and Luxullianite appears Veined or Pebbled. The luster of Chalk is dull while that of Luxullianite is dull to grainy with sporadic parts pearly and vitreous. Chalk is available in grey, white, yellow colors whereas Luxullianite is available in black, grey, orange, pink, white colors.
