Abstract
A previously unrecognized fold structure some 10 by 25 km, consisting of a steeply southward‐plunging syncline and anticline, has been mapped in the Woolomin Beds north of Woodsreef, New South Wales. This is an F2 structure which may be interpreted as a drag fold formed as a result of sinistral motion along the Peel Fault about the time of the Carboniferous‐Permian boundary. Prior to this, earlier isoclinal folding with a bedding‐plane cleavage is thought to have been associated with the overthrusting of the Woolomin Beds over the sediments of the Tamworth Trough to the west.
