- Permian and Triassic plutonic complexes comprise monzonite, granite, granodiorite or tonalite with minor gabbro and diorite.
- Implicit in this emplacement model is that the Permian and Triassic plutonic complexes are tabular granites with length and width dimensions that are much greater than their thickness.
- Low-angle unconformities can be observed between the Triassic and Jurassic rocks at outcrop scale.
- Uppermost Permian and Triassic terrestrial sediments conformably overlie the terminal volcanic rocks.
- In the Mesozoic section, a Triassic basin, up to 1800 m thick and roughly circular in map view, is centred SW of the present uplifted Bishri block.
