Results from different techniques, often measured in rival labs, continually confirm each other.

Every few years, new geologic time scales are published, providing the latest dates for major time lines.

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.

It will serve as the most comprehensive treatise on widely accepted dating methods in the earth sciences and related fields.Using new samples of feldspar and pumice they ‘reliably dated’ the tuff at 2.61 million years, which agreed nicely.Later, this date was confirmed by two other dating methods (paleomagnetism and fission tracks), and was widely accepted.All these labors have not led to a single unexpected finding such as a human fossil from the time of the dinosaurs, or a Jurassic dinosaur in the same rocks as Silurian trilobites.Paleontologists now apply sophisticated mathematical techniques to assess the relative quality of particular fossil successions, as well as the entire fossil record.
