"This book begins with an introduction to the theory and methodology behind the construction of the new time scale. The main part of the book is devoted to the scale itself, systematically presenting the standard subdivisions at all levels using a variety of correlation markers. Extensive use is made of stable and unstable isotope geochronology, geomathematics, and orbital tuning to produce a standard geologic scale of unprecedented detail and accuracy with a full error analysis. A wallchart summarizing the whole time scale, with paleogeographic reconstructions throughout the Phanerozoic is included in the back of the book. The time scale will be an invaluable reference source for academic and professional researchers and students."--BOOK JACKET.
