Lower to upper Middle Ordovician quartz-rich turbidites form the bedrock of the Lachlan Orogen in the southern Tasmanides of eastern Australia and occupy a present-day deformed volume of ∼2–3 million km 3 . We have used U–Pb and Hf-isotope analyses of detrital zircons in biostratigraphically constra...
