Stockholm UniversitySweden

Nils-Axel Mörner took his PhD in Quaternary Geology at Stockholm University in 1969. He was head of a personal institute at Stockholm University and the Swedish National Council on Paleogeophysics & Geodynamics (P&G) from 1991 up to his retirement in 2005. He has written hundreds of research papers and a number of books. He is a global traveller and has undertaken field studies in all continents. Several students have taken their doctoral degree at the P&G institute, which became an international centre for paleoseismics, neotectonics, paleomagnetism and global sea level changes. He was president of the INQUA Neotectonics Commission (1981-1989) and president of the INQUA Commission on Sea Level Changes and Coastal Dynamics (1999-2003). From 1996 he has been deeply engaged in paleotsunami research in Sweden and the Maldives. In 2008 he was awarded the Golden Condrite of Merit (from Algarve University) “for his irreverence and contribution to our understanding of sea level change”.

Chronology is the backbone of history, and there is a wise saying stating there is no history without a chronology. Earths evolutionary history is built up by geochronology, i.e. time benchmarks upon which the geological history is built up step by step over its total time period of about 4.5 billion years. The first marker in this history is the Jack Hills zircon from Australia dated at about 4.4 GA. The most detailed records come from seasonal changes within annual varves. Stratigraphy provides the basic chronological ordering of layers by layers, units by units, fossil assemblage by assemblage, varves by varves, growth zone by growth zone, etc. The radiometric techniques implied the introduction of absolute age determinations. This book includes a combination of methodological presentations and related case studies, from where we learn about practical problems and achievements. Therefore, the book should be of basic interest both for scientists in their practical in field and laboratory, as well as for general educational purpose.
