Monzogranite and Trondhjemite


Trondhjemite and Monzogranite


Definition

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   
Trondhjemite is a leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites.

Formation

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.   
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.
