    • Linking the basement geology along the Africa-South America coasts in the South Atlantic 

      Konopasek, Jiri; Slama, Jiri; Košler, Jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-13)
      The match of geological units of the dissected Kaoko-Dom Feliciano-Gariep orogenic system exposed along the coasts of the South Atlantic is poorly understood. Two suites of intrusive rocks crop out in the Angra Fria Bay area, a part of the Coastal Terrane of the Kaoko Belt in Namibia. U–Pb zircon dating of three samples from the younger suite provided ages of 574 ± 6, 586 ± 3 and 584 ± 7 Ma, similar ...

    • The onset of flysch sedimentation in the Kaoko Belt (NW Namibia) – Implications for the pre-collisional evolution of the Kaoko–Dom Feliciano–Gariep orogen 

      Konopásek, Jiří; Hoffmann, Karl Heinz; Sláma, Jiří; Košler, Jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-17)
      <p>Detrital zircon provenance study of a metamorphosed sedimentary succession in the eastern part of the Kaoko Belt in Namibia has revealed two distinct sources for the Neoproterozoic sedimentation along the southwestern Congo Craton margin. The lower part of the succession shows detrital zircon ages consistent with erosion of Paleoproterozoic basement of the Congo Craton with an inferred Mesoproterozoic ...
