Zircon geochronology of the Oribi Gorge Suite, KwaZulu-Natal, South Africa: constraints on the timing of trans-current shearing in the Namaqua-Natal Belt

Eglington, B.M.; Thomas, R J; Armstrong, Richard; Walraven, F

Description

The Oribi Gorge Suite is a voluminous suite of rapakivi granite-chamockite plutons which occur in the Mzumbe and Margate terranes of the eastern (Natal) sector of the Mesoproterozoic Namaqua-Natal Belt of Southern Africa. Previous geochronological studies have provided contradictory results for the age of emplacement of the suite. New single zircon evaporation dates and detailed SHRIMP zircon analyses for three of the plutons confirm the previously observed complexity with two episodes of...[Show more]
