Abstract
An overturned angular fold in the Currabubula Formation at Tulcumba Ridge has a north‐south axial trace exposed along the western side of this ridge. The geometry and position of this fold adjacent to the Mooki Thrust is consistent with its formation as a fault‐propagation fold involving a thrust step‐up angle of ∼ 30° from a decollement. Overturned strata also occur adjacent to the Mooki Thrust near the Rocky Creek Syncline to the north and to the south on Gunnan Ridge and in the Werrie Syncline. Overturning of strata in these areas may be the result of fault‐propagation folding. It is suggested that folding in the Tamworth Belt involves thin‐skinned deformation that is dominantly fault‐related.
