We present new U-Pb sensitive, high-resolution ion microprobe (SHRIMP) dates for zircon from eclogite facies samples from northern New Caledonia, which have important consequences for the Late Cretaceous to Eocene tectonic evolution of the southwest Pacific region. Two high-pressure metapelites contain zoned zircon crystals. Cores of these crystals represent inherited magmatic zircon grains, which yield an age of 85 Ma in both samples. Igneous zircon domains from a metamorphosed mafic cumulate...[Show more]
