Abstract

The Mossman Orogen is introduced here as a broad-scale crustal element, embracing the development and deformation of voluminous marine sedimentary and igneous rocks at the northeastern Australian continental margin in the Silurian and Devonian. It occupies the northern end of the Tasmanides and is positioned generally to the east of the Neoproterozoic-Ordovician Thomson Orogen. Its development postdates an episode of crustal contraction, the Benambran Orogeny, which has widespread expression in pre-Silurian rocks of the Thomson Orogen in central and northern Queensland. Its development was terminated by general folding and faulting of its component strata during a crustal shortening episode that is regarded here as part of the Tabberabberan Orogeny, which commenced near the end of the Devonian. The Tabberabberan Orogeny in the northern Tasmanides occurred during the late Devonian - early Tournaisian (Henderson 1980, p. 21 ; Glen 2005), rather than Middle Devonian as in the southern Tasmanides (Foster & Gray 2000; Glen 2005). The Mossman Orogen overlaps in time, but is spatially separate from, the New England Orogen , which is thought to extend along its eastern margin.
