The project aims were to understand the regional structure of the Dundas Trough and to apply this understanding to ore deposit and exploration models. So far the Devonian structural history has been well determined for four regional sections and at Rosebery and Mt Lyell. The Cambrian structure has been partly determined with a clear Middle Cambrian extensional phase followed by a compressional or wrench phase in the Late Cambrian. The significance of these Cambrian events must be considered in the light of the synchronous compressional tectonics in South Australia and Northern Victoria Land. Tasmania was in an active tectonic zone in the Late Cambrian.
