摘要：
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; Reunion 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.
