Quaternary Dating Methods


Product Description
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.

Quaternary Dating Methods Review
Mike Walker does us a huge favor in writing such a detailed, technical account of modern dating methods that range from tree rings (dendochronology) to isotopes (radiometric dating). He starts off with a history on dating methods and the search to find a reliable "clock" that range from using chronologies to isotopes. He then talks about certainties, precision, accuracy of dating methods and how scientists decide when to trust and when not to trust a certain date resulting from an instrument or dating technique. Throughout the book, Mike Walker carries the reader through and describes instruments and machines used in dating methods like for example, the 5-Mv Accelerator Mass Spectrometer used for Radiocarbon Dating objects.It should be noted that this book deals with methods used for up to the Quaternary period dating, not beyond. That is, it is these methods are used for dates up to around 2.5 million years ago. No further.
There are numerous examples that are in-depth, for each dating method discussed in the book. For example, actual tree ring data (dendochronology) used to detect and estimate climate changes throughout Europe, Asian, and North America. Or Radiocarbon dating examples such as results of a few skulls of Mexican Palaeo-Americans with confidence levels and also results of the estimated ages of the Shroud of Turin as a result of Radiocarbon Dating.
Furthermore, Mike mentions and discusses the errors and examples of erroneous results from each of the dating methods found in this book. Also he discusses results that give way to certain philosophies such "apparent young age" results from U-Series dating. He is not afraid to talk about some conflicts within dating methods themselves such as 24 dates received for paintings at Cosquet Caves that range from 28,000 to 19,000 years ago. The interval of a 9,000 years means high uncertainty compared to the normal uncertainty ranges of less than 1,000 when the object is in the 1,000 to 60,000 years-ago ranges.
Here is the general basic setup of the chapters:
1. summary of Dating Methods themselves
2. instruments or machines used to obtain the data
3. problems and sources of error with the Dating methods
4. applications and actual dating of land, artifacts, and hominids
Overall, there is lots of information here for anyone who is interested in how certain anyone can be about ages claimed in the fields of science. Bravo for Mike Walker.

Hope this encourages people to buy this. This book too deserves a wide audience.
For further reading on dating methods (mostly Radiometric) and their foundations please look at Isotopes: Principles and Applications,Stable Isotope Geochemistry, Principles of Stable Isotope Geochemistry and others.
On a related note, anyone interested in the natural philosophy, evidence, and history of the age of the earth please read The Age of the Earth, Ancient Earth, Ancient Skies: The Age of Earth and its Cosmic Surroundings, and also read Radioisotopes and the Age of the Earth: A Young-Earth Creationist Research Initiative to balance the research by reading varying view points.
