Provenance and tectonic development of the late Archaean Gawler Craton, Australia; U-Pb zircon, geochemical and Sm-Nd isotopic implications

Swain, G; Woodhouse, Ailsa; Hand, Martin; Barovich, K.; Schwarz, M; Fanning, Christopher


Integrated Sensitive High Mass Resolution Ion Microprobe (SHRIMP) U-Pb zircon, geochemical and Sm-Nd isotopic data from the late Archaean Gawler Craton, southern Australia, constrain major basin-forming and magmatic processes to the interval 2560-2500 Ma. This terrane represents a convergent margin associated with the second half of a full global Wilson cycle, during which continental fragments formed between 2780 and 2590 Ma amalgamated with younger cratons, perhaps forming the Earth's first...[Show more]
