Dating the Quaternary, which covers approximately the last 2 million years, has experienced considerable progress over the past few decades. On the one hand, this resulted from the necessity to obtain a valid age concept for this period which had seen tremendous environmental changes and the advent of the genus Homo. On the other hand, instrumental improvements, such as the introduction of highly sensitive analytical techniques, gave rise to physical and chemical innovations in the field of dating. This rapid methodological development is still in full progress. The broad spectrum of chronometric methods applicable to young rocks and artifacts also becomes increasingly intricate to the specialist. Hence, it is my goal to present a comprehensive, state-of-the-art sum mary of these methods. This book is essentially designed as an aid for scientists who feel a demand for dating tasks falling into this period, i. e., Quaternary geologists and archaeologists in the broadest sense. Since it has been developed from a course of lectures for students of geological and archaeological sciences, held at the University of Heidelberg, it certainly shall serve as an introduction for students of these disciplines.
