The contorted New England Orogen (eastern Australia): New evidence from U-Pb geochronology of early Permian granitoids

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

Description

A series of sharp bends (oroclines) are recognized in the Paleozoic to early Mesozoic New England Orogen of eastern Australia. The exact geometry and origin of these bends is obscured by voluminous magmatism and is still debated. Here we present zircon U-Pb ages that confirm the lateral continuation of early Permian (296-288 Ma) granitoids and shed new light on the oroclinal structure. Orogenic curvature is defined by the alignment of early Permian granitoids parallel to the structural grain of...[Show more]
