dc.description.abstract | Geochemical & Nd¡VHf isotopic data are reported for dolerite samples from the Neoproterozoic (755 Ma) Mundine Well dyke swarm in northwestern Australia. These dolerites are tholeiitic in composition, crystallised from a common parental magma. Although the dolerite magma underwent varying degrees of crustal contamination during ascent & emplacement, the uncontaminated parental melt possessed geochemical & Nd isotopic characteristics, such as Nb/La?1.5, Nb/Th?15, Nb/U?50, Nd(T)?5, & Hf(T)?9 (estimated by extrapolation from geochemical correlations), that closely resemble plume-derived ocean island basalts. These features are also similar to those of dolerite dykes of similar age from Seychelles & South China.We propose that these late Neoproterozoic mafic suites may have been generated by melting of a vast asthenospheric mantle superplume that developed beneath, & led to breakup of, the Rodinia supercontinent. | en |
