LATE CARBONIFEROUS
The gold mineralisation at Mount Wright is associated with a Permo-Carboniferous rhyolite which intrudes the Early to Middle |
Ordovician Millaroo Granite in the eastern portion of the Ravenswood Batholith. |
The bulk of the mineralisation is hosted by altered and brecciated rhyolite with a small amount hosted by granite breccia. This |
mineralisation is thought to be a mineralised diatreme breccia lying above an originally volatile-charged rhyolite intrusive. |
