Grenville-age magmatism at the South Tasman Rise (Australia): A new piercing point for the reconstruction of Rodinia

A U-Pb zircon sensitive high-resolution ion microprobe age of 1119.4 ± 8.5 Ma, obained from a quartz syenite dredged from the South Tasman Rise (Australia), provides the first direct evidence of the presence of Grenville-age magmatic rocks along the cent
