McDougall, I., Brown, F.H., Cerling, T.E. and Hillhouse, J.W. (1992). A reappraisal of the geomagnetic polarity time scale to 4 MA using data from the Turkana Basin, East Africa. Geophysical Research Letters 19: doi: 10.1029/92GL02714. issn: 0094-8276.

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; R¿union 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. ¿American Geophysical Union 1992
