Age of Metavolcanic rocks at the northern margin of the Namaqua-Natal Metamorphic Province in the Karas Mountains, Namibia, defined by SHRIMP U-Pb dating of zircons

Evans, D.M.; Windrim, D.P.; Armstrong, Richard

Description

Mapping in the Karas Mountains area of southern Namibia has shown the presence of a major lithotectonic boundary at the northern margin of the Namaqua-Natal Metamorphic Province. The area is subdivided into the Northern Volcanic Zone largely comprising mafic, intermediate and felsic volcanic and intrusive rocks metamorphosed to greenschist to amphibolite facies, and the Southern Sedimentary Zone, dominated by pelitic rocks, metamorphosed at amphibolite to granulite facies, and intruded by...[Show more]
