Formation
Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
Monzonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Chalk and Monzonite Properties
Know all about Chalk and Monzonite properties here. All properties of rocks are important as they define the type of rock and its application. Chalk belongs to Sedimentary Rocks while Monzonite belongs to Igneous Rocks.Texture of Chalk is Clastic or Non-Clastic whereas that of Monzonite is Phaneritic. Chalk appears Soft and Monzonite appears Shiny. The luster of Chalk is dull while that of Monzonite is subvitreous to dull. Chalk is available in grey, white, yellow colors whereas Monzonite is available in black, brown, light to dark grey, white colors. The commercial uses of Chalk and Monzonite 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.
