Monzonite and Chalk

Monzonite

Chalk

Definition

Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase

Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers

Formation

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.

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

All about Monzonite and Chalk Properties

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