Description
New U-Pb zircon SHRIMP dates are presented for two critical meta-igneous rock units from the Scottburgh area, central Mzumbe Terrane, Natal Sector of the Namaqua-Natal Metamorphic Province ("Natal belt"). A sample of the oldest syntectonic granitic orthogneisses of the Mzumbe Terrane, the Mzimlilo Granite, gave a date of 1147 ± 8 Ma. This is interpreted to represent the crystallisation age and thus gives a reliable minimum estimate of the age of the first, collision-related tectono-metamorphic...[Show more]
