ABSTRACT
Geomorphological evidence provides a useful starting point in the investigation of Quaternary environments. Geomorphological evidence has frequently been cited in support of readvances of the Late Devensian ice sheet. The production of a map illustrating the distribution of the principal landforms is often the first stage in the investigation of the Quaternary history of an area. The pronounced oscillations in global climate that occurred during the Quaternary led to major changes in the types and rates of operation of geomorphological processes. There is abundant geomorphological and lithological evidence to show that major climatic changes have affected the tropical, subtropical and warm temperate regions of the world during the Quaternary. Geomorphological evidence for the existence of pluvial lakes and for oscillations in water level includes abandoned clifflines, shorelines, beaches, bars and deltas, as well as abandoned watercourses that acted as overflows at times of high lake-level.
