Abstract
The western sub-province of the Paleozoic Lachlan Orogen in Victoria is dominated by thick turbidite sequences overlying Cambrian basement volcanics. The region was subjected to multiple Cambrian to Late Devonian regional deformation events, followed by extensive post-tectonic granitic magmatism. The western Lachlan Orogen is considered a typical 'orogenic' gold province and hosts a large number of goldfields, including the world-class Bendigo-Ballarat goldfields. A variety of geochronological methods (e.g. U-Pb zircon; Re-Os sulfide; 40Ar/ 39Ar whole-rock, mica) have been used to constrain the timing of gold mineralisation, and the relationship to metamorphism/deformation/ magmatism.
