Things We Sometimes Overlook after Ocean Closure: Examples from the Phanerozoic of Eastern Australia |
The prevailing ‘consensus’ explanation for Phan-erozoic development of eastern Australia envisages a ‘retreating accretionary orogen’ in which episodic slab retreat resulted in development of offshore island arcs in front of marginal basins. Periodically, this was fol-lowed by intervals of plate-coupling during which these basins close and the arcs are retro-thrust back onto the continental margin. Implicit in this model is the notion that all elements developed in an upper plate location upon the accretionary margin and that west-dipping subduction beneath eastern Gondwana was a long-lived phenomenon. |
