[QUOTE="user 4386, post: 584456, member: 4386"] Mostly too far north for the last glacial periods. A few glaciers on higher areas in Tasmania and Kosciusko range. And even Antarctica lacked ice for some time prior to the latest - present- ice age (started about 2 My ago). Have to go back to the Permian (250 My) - rumoured to be some near Bacchus Marsh but I doubt it. Might be some that age in NSW but if so, insignificant. Could speculate that some around Beechworth- but also insignificant if so. Few alluvial goldfields in Australia formed more than 60 My ago, give or take (Palaeocene-Eocene). A few formed in Cretaceous in NSW, approx. 150 My (eg edge of Sydney Basin), but they were fossil rivers, not glacial. Same age at Tibooburra. Age chart attached.....sorry it is a PDF so cant do [/QUOTE]
