Amphibolites of the central zone: New shrimp U-Pb ages and implications for the evolution of the Damara Orogen, Namibia

Longridge, Luke; Kinnaird, Judith A.; Gibson, Roger L.; Armstrong, Richard

Description

New SHRIMP U-Pb zircon and titaniie data are presented for two amphibolites from the Central Zone of the Damara Orogen, Namibia. These data (the first ages for amphibolites in the Central Zone) show that amphibolites are derived from both Palaeoproterozoic (2026.9 ± 2.3 Ma-sample ACAM-1) and Pan-African (557.2 ± 7.4 Ma-sample LKR021) precursors emplaced into the Palaeoproterozoic Abbabis Complex basement in the Central Zone. The younger amphibolites are interpreted as part of a mafic to...[Show more]
