- Description
- The Manning Orocline is an enigmatic structure that has been the subject of much speculation with those advocating its existence to those sceptical of its existence (Lennox et al., 2013). In their recent contribution, Li and Rosenbaum (2014) provide evidence for this structure by analysing the geometry of the structural fabrics in the Armidale–Walcha area, an area that they suggest, comprises a less deformed part of the subduction–accretion complex of the southern New England Orogen. We will present evidence in the following sections that show that pre-oroclinal structures have not been obliterated and that the area of interest has inherited a complex structural-metamorphic history related to the Carboniferous subduction–accretion history of the rocks. In addition, we will show that careful petrographic and field studies are essential to confirm the type and timing of cleavage formation before any model can be proposed. Finally, we will comment on some statements and interpretations presented in the paper but not on others that have been addressed in Lennox et al. (2013).
