• Format: PDF

Produktbeschreibung

This introductory textbook introduces the basics of dating, the range of techniques available and the strengths and limitations of each of the principal methods. Coverage includes: * the concept of time in Quaternary Science and related fields * the history of dating from lithostratigraphy and biostratigraphy * the development and application of radiometric methods * different methods in dating: radiometric dating, incremental dating, relative dating and age equivalence Presented in a clear and straightforward manner with the minimum of technical detail, this text is a great introduction for both students and practitioners in the Earth, Environmental and Archaeological Sciences. Praise from the reviews: "This book is a must for any Quaternary scientist." SOUTH AFRICAN GEOGRAPHICAL JOURNAL, September 2006 "...very well organized, clearly and straightforwardly written and provides a good overview on the wide field of Quaternary dating methods..." JOURNAL OF QUATERNARY SCIENCE, January 2007
