1.1 Definition

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.

Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

5 Formation

5.1 Formation

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

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
