Definition
Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture
Monzogranite is a type of igneous rock and belongs to biotite granite rocks that are considered to be the final fractionation product of magma

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

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