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.
In this paper we report U-Pb age data on titanite from an augen granitoid mylonite
in the eastern part of the DPDZ.
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.
Such rocks can be seen in mylonite
shales spread in thrust formations on top of Saanavuori.

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
