- Monazite clusters occur in a variety of host minerals, including cordierite, quartz, biotite and andalusite.
- From Pliocene time the shallow emplacement of intrusive bodies resulted in thermal metamorphism (forming, for example, biotite, cordierite, andalusite, K-feldspar and corundum in pelites) and hydrothermal activity.
