Detrital zircon from two basement blocks (Kubor and Bena Bena) in the central Highlands of Papua New Guinea has an age signature that strongly suggests a northern Australian provenance. Samples of the Omung Metamorphics, southeastern Kubor Block, together yield principal zircon populations with ages of ca 1.8 Ga (∼10% of the total), ca 1.55 Ga (∼10%), 470-440 Ma (∼15%), ca 340 Ma (∼10%) and 290-260 Ma (∼40%). Two tonalite stocks of the Kubor Intrusive Complex, which intrude the Omung...[Show more]
