GAMBLIAN PLUVIAL STAGE

major division of Pleistocene rocks and time in Africa (the Pleistocene Epoch began about 1,600,000 years ago and ended about 10,000 years ago). The Gamblian Pluvial, a moist period that began about 30,000 years ago and lasted about 20,000 years, followed the Kanjeran Pluvial Stage and preceded the Makalian Wet Phase, from each of which it was separated by a period of drier conditions. The Gamblian has been equated in time with the major portion of the Wrm Glacial Stage of Europe. Three phases of the Gamblian have been recognized in depositional features along prominent lakeshores. Dates for the various phases of the stage are well established on the basis of radiometric techniques. During the Gamblian, eastern Africa was the scene of prominent Earth movements.
