New age constraints on the tectonogenesis of the Kheis Subprovince and the evolution of the eastern Namaqua Province
Mapping and stratigraphic analysis of the rocks adjacent to the Kaapvaal Craton east of Upington has suggested that the area previously defined as the Kheis Subprovince was deformed and metamorphosed not during the so-called Eburnean "Kheis Orogeny" but as the result of a considerably younger event. U-Pb zircon SHRIMP ages on sedimentary as well as volcanic and plutonic rocks show that the arenitic successions that dominate the area were derived from a provenance similar in geochronological...[Show more]
