Three new U-Pb zircon ages are reported for early Damaran, rift-related, igneous rocks in northern Namibia. An age of 756 ± 2 Ma for the Oas quartz syenite intrusion, western Welwitschia Inlier, provides a minimum age for lower Nosib Group terrigenous sedimentation in that area. An ash-flow tuff near the top of the Lower Naauwpoort Formation (upper Nosib Group) in the Summas Mountains and a rhyolite lava flow in the Upper Naauwpoort Formation (lower U gab Group) directly north of the Summas Mountains have statistically identical ages of 746 ± 2 and 747 ± 2 Ma, respectively. The age equivalence indicates that the contact between the sampled Upper and Lower Naauwpoort Formations represents either a brief hiatus or a tectonic repetition. Rift-related magmatism in northern Namibia is similar in age to that in northwest India, the Trans-Antarctic Mountains, and the northern Cordillera and southern Appalachians of North America.
