Interpreted as Archean paleo - rift zones, one of these runs N - S through the Eastern Goldfields Superterrane (broadly coincident with the Kurnalpi Terrane) and is associated with the high grade ca. 2690 Ma Teutonic Bore, Jaguar and Bentley deposits, plus sub - economic VHMS mineralization further south. To date, only small, historic Cu deposits (e.g. Anaconda) and barren pyritic lenses have been recognised in the older 2.7 Ga plume - dominated lower stratigraphy of the Eastern Goldfields.||Type of material:||Conference Publication||Publisher:||Taylor & Francis||Keywords:||Gallium; Volcanic-hosted massive sulfide; Australia||Language:||en||Status of Item:||Peer reviewed||Conference Details:||35th International Geological Congress, Cape Town, South Africa, 27 August -04 September 2016|
