Triassic asymmetric subduction rollback in the southern New England Orogen (eastern Australia): the end of the Hunter-Bowen Orogeny

Li, P-F.; Rosenbaum, Gideon; Rubatto, Daniela

Description

The New England Orogen, the youngest subduction-related component in the Australian continent, records a prolonged history of west-dipping subduction from the Devonian to the Triassic. From mid-late Permian (ca 265 Ma) to Upper Triassic (ca 235 Ma), the New England Orogen was subjected to pronounced contractional deformation (Hunter-Bowen Orogeny) and widespread I-type calc-alkaline magmatism. We obtained zircon U-Pb ages from seven granitic samples within the I-type magmatic system. The new...[Show more]
