This volume provides an overview of (1) the physical and chemical foundations of dating methods and (2) the applications of dating methods in the geological sciences, biology, and archaeology, in almost 200 articles from over 200 international authors.It will serve as the most comprehensive treatise on widely accepted dating methods in the earth sciences and related fields.This new date agreed with the appearance of the new skull.Tests by other scientists using paleomagnetism and fission tracks confirmed the lower date.A key point is that it is no longer necessary simply to accept one chemical determination of a rock’s age.Age estimates can be cross-tested by using different isotope pairs.Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.These skeptics do not provide scientific evidence for their views.

Dating methods are used to determine the timing and rate of various processes, such as sedimentation (terrestrial and marine), tectonics, volcanism, geomorphological change, cooling rates, crystallization, fluid flow, glaciation, climate change and evolution.The volume includes applications in terrestrial and extraterrestrial settings, the burgeoning field of molecular-clock dating and topics in the intersection of earth sciences with forensics.The content covers a broad range of techniques and applications.So by 1980 there was a new, remarkably concordant date for the KBS tuff, and this became the one that was widely accepted.

Which illustrates that, contrary to popular belief, the dating methods are not the primary way that ages are decided. Their results are always ‘interpreted’ to agree with other factors, such as the evolutionary interpretation of geology and fossils.

Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.
