Definition
Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).
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
Nephelinite 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.
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 Nephelinite and Monzogranite Properties
Know all about Nephelinite and Monzogranite properties here. All properties of rocks are important as they define the type of rock and its application. Nephelinite and Monzogranite belong to Igneous Rocks.Texture of Nephelinite is Aphanitic whereas that of Monzogranite is Porphyritic. Nephelinite appears Skeletal and Monzogranite appears Veined or Pebbled. The luster of Nephelinite is vitreous to metallic while that of Monzogranite is dull to grainy with sporadic parts pearly and vitreous. Nephelinite is available in black, brown, colourless, green, grey, white colors whereas Monzogranite is available in black, grey, orange, pink, white colors. The commercial uses of Nephelinite are creating artwork, soil conditioner, source of magnesia (mgo) and that of Monzogranite are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
