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.
