Definition
Enderbite rock is an igneous rock which belongs to the Charnockite rock series
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
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.
