Abstract
Historically the emphasis on unraveling the structural geodynamic history of the Eastern Goldfields Superterrane of the Western Australian Yilgarn Craton has been on compression. A systematic study of: structural overprinting relationships; links with the rock record and architecture, reveals extension has been the dominant tectonic mode of the geodynamic history of the Eastern Goldfields. Extension was associated with: the deposition of the greenstone sequence; the emplacement of voluminous granites; the onset of Au mineralisation; dextral trans-tension and subsequent orogenic collapse. While compression or transpression structures host the majority of Au mineralisation these events are restricted to short protracted periods of time.
