Abstract

"The scheme currently used in east Africa for Pleistocene stratigraphic correlation is based on climate. This basis is thought to be undersirable because it consists of second-order concepts rather than of primary, objective units and because its unconventional character inhibits correlation between east Africa and other regions. Furthermore the conceptual sequence of pluvial and interpluvial Pleistocene climates is not fully supported by the field evidence described thus far. Local support exists for the Gamblian and post-Gamblian wet climates, and at one locality a wet phase of pre-Gamblian age is admissible. The other units of the current scheme require factual support before they can be accepted. Is is suggested that a more conventional basis of Pleistocene correlation in east Africa is desirable."
