U-Pb zircon geochronology of Silurian-Devonian granites in southeastern Australia: implications for the timing of the Benambran Orogeny and the I-S dichotomy

Ickert, Ryan; Williams, Ian

Description

Despite extensive geochemical study and their importance to granite studies, the geochronology of Silurian to early-Devonian granitic rocks of southeastern Australia is poorly understood. In order to provide an improved temporal framework, new ion microprobe U-Pb zircon ages are presented from these rocks, and previous work is critically reviewed. Geochronological control is best in the Berridale Batholith, where S- and I-type granites have a close spatial relationship. In this region, there is...[Show more]
