In situ determination of U-Pb ages and Sr-Nd-Hf isotopic constraints on the petrogenesis of the Phalaborwa carbonatite Complex, South Africa

► A comprehensive zircon and baddeleyite U-Pb age determination is conducted for the Phalaborwa Complex. ► The various phases were synchronously emplaced at ~ 2060 Ma. ► The Complex has high initial Sr and low initial Nd and Hf isotopic compositions. ► The primary carbonatitic magma was derived from an enriched mantle. ► The Phalaborwa carbonatite magmatism was triggered by a mantle plume related to the Bushveld event.
