Abstract
Recalibration of the Pliocene and early Pleistocene geomagnetic time scale using the K‐Ar dated fluvial sequence of the Turkana Basin in East Africa agrees with calibrations based on astronomical calculations. Ages estimated here are: Olduvai Subchron, 1.78–1.96 Ma; Réunion Subchrons, 2.11–2.15 Ma and 2.19–2.27 Ma; Matuyama‐Gauss boundary, 2.60 Ma; Kaena Subchron 3.02–3.09 Ma; Mammoth Subchron, 3.21–3.29 Ma; Gauss‐Gilbert boundary, 3.57 Ma.This publication has 19 references indexed in Scilit:
