5 Formation
5.1 Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

All about Granulite and Chalk Properties

Know all about Granulite and Chalk properties here. All properties of rocks are important as they define the type of rock and its application. Granulite belongs to Metamorphic Rocks while Chalk belongs to Sedimentary Rocks.Texture of Granulite is Granoblastic whereas that of Chalk is Clastic or Non-Clastic. Granulite appears Veined or Pebbled and Chalk appears Soft. The luster of Granulite is vitreous while that of Chalk is dull. Granulite is available in black, brown colors whereas Chalk is available in grey, white, yellow colors. The commercial uses of Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones and that of Chalk are alumina refineries, creating artwork, drawing on blackboards, gymnasts, athletes and mountain climbers use for grip, in aquifers, paper industry, production of lime, raw material for manufacture of quicklime, slaked lime, soil conditioner, whiting, whiting material in toothpaste, paint and paper.
