The evident unconformable contacts in Timber Brook and in the lower reaches of North River, where windows through the Carboniferous sequence reveal underlying units of diorite, granodiorite, gneiss and mylonite, lie to the east of the main block of thrusted rocks, and appear to be unrelated to the thrust contacts identified here.
The southern limit of the Chidue Formation rocks is marked by a wide mylonite zone striking at 290 degrees and dipping 45 degrees to the southwest.
The gabbro-diorite intrusion is within silicified felsic schist and mylonite of a linear zone referred to as the Pistol Bay Corridor.
The project area includes the Roopena Fault and Kalinjala Mylonite structures, which offer potential sites for economic deposits sourced from Hiltaba granites to the north and in the eastern portion of the project area.
Of course rock is created from the bottom up, but the accepted explanation is an anomaly in which complete plates were forced up and over shallower ones using a layer of fine-grained mylonite limestone as a lubricant.

The schists also show that extreme deformation has occurred and mylonite bands are common.
The Vickers Target is an elliptical, 1 kilometre diameter, gabbro-diorite intrusive complex within silicified schist and mylonite of the Pistol Bay Corridor.
These rocks are typically more deformed than those in the western belt and in places discrete mylonite zones are present, which appear to correspond to the "gneissoid" beds of Fletcher (1881).
This rock unit, along with a thick sequence of supracrustals, forms the hanging wall to a quartz sericite altered mylonite zone.
