The main focus of the book is the last deglaciation - a period of intense and rapid climatic changes which affected the global climate approximately 20,000 to 50,000 years ago. Special emphasis is placed on the timing of the last deglaciation in order to provide a common absolute chronological framework for the numerous researchers in the field. Accordingly, results obtained from the various scientific disciplines, relevant for the chronological problem, are reviewed and discussed: from glaciology, varved clay sedimentology, paleomagnetism, dendrochronology and radiochronology (14C and U/Th).

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Time is a major factor in Quaternary science. Without a trustworthy chronometer any interpretation of changes in proxy data of stratigraphical origin is on weak ground. In fact, any attempt at a sound reconstruction of timing and rates of past climatic change as well as the response of the biosphere can only be achieved on the basis of a reliable chronology. Moreover, all correlations and comparisons through time on a continental or global scale depend heavily on the reliability of the time-scale used. Therefore the establishment of an absolute time-scale is a fundamental goal. In this contribution we refer to the term 'absolute time-scale' as a time-scale consisting of ages determined on the basis of sidereal years. Traditional stratigraphical methods of absolute dating include the Swedish glacial varve chronology, already developed early in this century by De Geer (1912) and since then continuously improved (e.g. Stromberg 1985; Cato 1987). Unfortunately, however, a spatial correlation with other stratigraphies outside Fennoscandia is difficult. Artikel-Nr. 9783642760617
