Low δ 18 O zircon grains in the Neoarchean Rum Jungle Complex, northern Australia: An indicator of emergent continental crust

Hollis, J A; Van Kranendonk, M J; Cross, Andrew; Kirkland, C L; Armstrong, Richard; Allen, C M

Description

The timing of widespread continental emergence is generally considered to have had a dramatic effect on the hydrological cycle, atmospheric conditions, and climate. New secondary ion mass spectrometry (SIMS) oxygen and laser-ablation-multicollector-inductively coupled plasma-mass spectrometry (LA-MC-ICP-MS) Lu-Hf isotopic results from dated zircon grains in the granitic Neoarchean Rum Jungle Complex provide a minimum time constraint on the emergence of continental crust above sea level for the...[Show more]
