... the paleo-Pacific subduction dynamics at the Gondwanan margin and the formation of curved orogenic belts in general. Here we present new constraints on the role of vertical-axis block rotations in the New England oroclines using paleocurrent indicators from the core of the oroclinal structure (the Nambucca...

...-type granitoids, high-temperature metamorphism, exhumation of metamorphic complexes, extensional faulting, and development of rift basins. One of these basins is the Early Permian Nambucca block, which is situated in the “core” of the oroclinal structure, but its origin and time of deposition...

... occurred during the Early to Middle Permian (280-265 Ma). They relate this to the intense deformation of the Nambucca block ( Leitch 1978 ; Coney et al. 1990 ), and infer a north-to-south 450-500 km relative movement above a sub-horizontal décollement ( Korsch et al. 1990 ).
