The History of the Study of Landforms or the Development of Geomorphology: Volume 5: Geomorphology in the Second Half of the Twentieth Century
CONTAINS OPEN ACCESS
This volume is the fifth in the definitive series, The History of the Study of Landforms or the Development of Geomorphology. Volume 1 (1964) dealt with contributions to the field up to 1890, Volume 2 (1973) with the concepts and contributions of William Morris Davis and Volume 3 (1991) covered historical and regional themes during the ‘classic’ period of geomorphology (1890–1950). Volume 4 (2008) concentrated on studies of geomorphological processes and Quaternary geomorphology between 1890 and 1965; by the end of this period, process-based studies had become dominant. Volume 5 builds on this platform, covering in detail the revolutionary changes in approach that characterized the study of geomorphology in the second half of the twentieth century. It is divided into three sections: the first deals with changes in approach and method; the second with changes in ideas and the broader scientific context within which geomorphology is studied; and the final section details advances in research on processes and landforms. The volume's objective is to describe and analyse many of the developments that provide a foundation for the rich and varied subject matter of twenty-first century geomorphology.

This chapter reviews the progress made between the years 1965 and 2000 in temporal techniques and their importance for the study of landforms. The chapter begins with discussion of advances in chronostratigraphy and of the important contributions to geomorphology that came from palaeoenvironmental reconstruction, notably through the study of marine sediments and ice cores. A more detailed discussion then follows of developments and advances in dating methods, grouped by radiometric and radiometric-related, incremental, age-equivalent markers, and relative, with emphasis on the ways in which the new techniques opened up new avenues in the study of landforms.
