The Devonian Narraburra Granite in southern New South Wales is located on the western margin of the Bogan Gate Synclinorium in the Temora Rift and is associated with other post- or late orogenic sodic granites and tholeiitic and transitional basic intrusive rocks. This region represents the rifted boundary between the Wagga-Omeo and Kosciusko Terranes. The granite is peralkaline (Al2O3/Na2O + K2O = 0.95–0.96), contains aegirine and arfvedsonite, and is only the third occurrence of peralkaline granite recorded in the Lachlan Fold Belt of southeastern Australia.
