An abrupt change in Nd isotopic composition in Australian basins at 1655Ma: Implications for the tectonic evolution of Australia and its place in NUNA

The Australo-Antarctic Columbia to Gondwana transition

“…1670 Ma the driver of rifting ceased. Lambeck et al (2012) interpreted a change from more evolved to more juvenile sediment sources for the eastern Australian basins at ca 1650 Ma.…”

Crustal architecture and geodynamics of North Queensland, Australia: Insights from deep seismic reflection profiling

“…The eastern part is much more reflective than the western part, and the boundary between the two parts has an open sigmoidal shape with a dip to the west. Recent work on the Etheridge Group (see , indicates that there is a major change in provenance between the lower and upper parts of the Group, which occurred at about 1650 Ma (Lambeck et al, 2010(Lambeck et al, , 2012. Above this boundary, exposed rocks of the upper Etheridge Group young to the west, and have been mapped as being conformable with the lower Etheridge Group.…”

The Victoria and Birrindudu Basins, Victoria River region, Northern Territory, Australia: a SHRIMP U–Pb detrital zircon and Sm–Nd study

“…Such relatively juvenile ca 1650 Ma material has been recognised across northern Australia, the Mount Isa and Broken Hill regions (e.g. Barovich & Hand 2008;Lambeck et al 2009Lambeck et al , 2012.…”
