Reply to discussion by C. L. Fergusson (2014) on 'Refining accretionary orogen models for the Tasmanides of eastern Australia' by R. A. Glen

摘要

While it is good to see that my paper on the evolution of the Tasmanides (Glen 2013) has spurred Fergusson (2014) into restating his views of supra-subduction zone activity in the Lachlan Orogen, I confess to being mystified as to why he bothered to formalise these opinions in a Discussion, which repeats his previous interpretations on the evolution of that orogen. Glen (2013) cited in several places that Fergusson was a proponent of the multiple, synchronous back-arc subduction zone models for which I suggested there were seven significant obstacles, the main one being the absence of linked arcs. All up, Glen (2013) cited 14 papers by Fergusson.
