Presented at the IAGR Conference in Adelaide 2012.
Outlines the Ordovician to Silurian evolution of North Queensland and concludes that the tectonic setting is related to the development of continental ribbons formed during subduction roll-back and subsequently re-amalgamated to the eastern margin of Gondwana.
Compares the tectonic setting with Proterozoic Australia.
