Definition
Monzogranite is a type of igneous rock and belongs to biotite granite rocks that are considered to be the final fractionation product of magma
Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture

Formation
Monzogranite 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.
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

All about Monzogranite and Chert Properties
Know all about Monzogranite and Chert properties here. All properties of rocks are important as they define the type of rock and its application. Monzogranite belongs to Igneous Rocks while Chert belongs to Sedimentary Rocks.Texture of Monzogranite is Porphyritic whereas that of Chert is Banded, Rough. Monzogranite appears Veined or Pebbled and Chert appears Glassy or Pearly. The luster of Monzogranite is dull to grainy with sporadic parts pearly and vitreous while that of Chert is waxy and dull. Monzogranite is available in black, grey, orange, pink, white colors whereas Chert is available in black, brown, green, grey, red, white colors. The commercial uses of Monzogranite are cemetery markers, commemorative tablets, creating artwork, curling, tombstones and that of Chert are creating artwork, gemstone, in fire-starting tools, jewelry, to ignite fire, used in flintlock firearms.
