Abstract

This is a comment on and discussion of the model proposed by Glen and Roberts (2012) for the formation of oroclines in the New England Orogen, Eastern Australia (view paper here). In particular, evidence is presented that shows that the Manning and Hastings Oroclines, an integral part of their model, do not exist.

Keywords: New England Orogen, orocline, megafold rotation, Permian
