Abstract

All the aims of the project have been met. The structural history determined has been tested over a large part of Western Tasmania and produces a workable structural synthesis. The Rosebery structural study has resolved many anomalies in the mine and produced an overview with some exploration significance. Several of the major controversies of the Mt Lyell field have been addressed and it is now possible to correlate structures with discrete events and place the mineralising events in their correct context. A study of the North Farrell mines supported earlier conclusions that this deposit is a Devonian granite-related vein system and provided additional detail on the nature of the fault controlled dilation. The geometry of the Cambrian extension which controlled VHMS formation has been defined over the Dundas Trough. This geometry has several significant features for exploration. In particular, there is a strong spatial association of economic mineralisation with transfer faults.
