... zircon ages from a leucogabbronorite in the Zebra Mountain lobe in Namibia (1385 ± 25 Ma) and from a syenodiorite (1376 ± 2 Ma). The latter may be equivalent to aplitic and pegmatitic syenitic segregations within the white anorthosites described by Köstlin (1967 , 1974) , suggesting that felsic...
