- Extensive areas within continental platforms are formed of basement, a complex of metamorphic and igneous rocks of Palaeozic or Precambrian age.
- Granulites are like their textural equivalents, granular igneous rocks, in being mosaics of interlocking crystals of roughly equal size.
- The same structural features, sometimes less easily recognized, are found in igneous and metamorphic rocks.
