1 Definition

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.

Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities

5.1 Formation

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

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
