The Naauwpoort quartz porphyry formed during local synsedimentary volcanism towards the end of the initial rifting phase in the central Damara belt of Namibia. SHRIMP U-Pb analysis of zircons from the Naauwpoort rhyolite dates this volcanism at 752±7 Ma whilst evaporation Pb-Pb analysis on the Kawakeup metarhyolite, a correlative unit from the southern Swakop terrane, suggests a minimum date of ~705 Ma. The pre-D2 Okongava Diorite provides a SHRIMP zircon date of 558±5 Ma which is much younger than previously thought. Inherited zircon cores in the diorite document the presence of ~2 Ga zircons in the source origin of the diorite.
