Orogenesis in Paleo‐Mesoproterozoic Eastern Australia: A response to Arc‐Continent and Continent‐Continent Collision During Assembly of the Nuna Supercontinent

Northern and southern Australia preserve a common record of 1790–1655 Ma intracontinental rifting and backarc extension culminating in formation of a marginal sea that subsequently collapsed following a 1650–1640 Ma reversal in plate motion and onset of arc‐continent collision. Arc‐continent collision was accompanied by intermediate‐pressure Barrovian‐type metamorphism (6–8 kb) and widespread crustal thickening as reflected in a clockwise...
