| Summary: | Abstract: The function of this study is to present preliminary paleomagnetic results so that a further in-depth study can be attempted in the future. Geochronological results suggest various separate ages of emplacement, with reliable ages at ~188 Ma, ~186 Ma, ~181 Ma and ~176 Ma. The paleomagnetic investigation yielded moderate inclinations for the high temperature components from the magnetometer. From the 8 dykes/sites that provided good results, the following paleopole was calculated: Plat = -52.1° & Plong = 181.0°, A95 = 13°, N = 8. Reconstructions comparing the paleomagnetic studies from the Mesoproterozoic and Mesozoic (including this thesis) suggest that separation between Africa and Antarctica occurred earlier than the generally accepted age of ~180 Ma, supported by early – ~210-206 Ma (Curtis et al., 2008; Morake, 2019; Riley et al., 2009) – dyke emplacement in Dronning Maud Land.
