Our study broadly confirms the established APWP, but reveals some previously unidentified complexities in the time interval ~2.05 Ga to ~1.87 Ga. A primary remanence direction from the lower part of the Swaershoek Formation provides a paleomagnetic pole of (36.5° north, 051.3° east, K = 23.4, A95 = 10.9) for the Waterberg unconformity-bounded sequence I (WUBS-I) at ~2.05 Ga. A large shift in pole position takes place from the lower Swaershoek into the upper Swaershoek Formation and overlying Alma Formation of Waterberg unconformity-bounded sequence II (WUBS-II; pole at −10.5° north, 330.4° east, K = 25.0, A95 = 9.8), confirming the existence of a major unconformity and/or rapid continental motion within the span of Swaershoek deposition.
