Request a sales quoteThe Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy.
This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field.
- The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access
- Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility
- Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events
- Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)
Professionals in industry (oil/gas/petrochemical industry), academic libraries, faculty chairs, graduate students/researchers. All geoscientists, more specifically biochronologists, evolutionary biologists, geo-engineers, space geo engineers, astronomers. Geoscience students, university teachers; all stratigraphic and paleontologic, quaternary geoscientists; individuals

Felix Gradstein
Felix Gradstein is Professor Emeritus at Oslo University, Norway and visiting Research Fellow, University of Portsmouth, UK. From 2000 to 2008, he was chair of the International Commission on Stratigraphy. Under his leadership major progress was made with the formal definition of chronostratigraphic units from Precambrian through Quaternary. For his fundamental work concerning the Geologic Time Scale, geochronology in general, quantitative stratigraphy and micropaleontology, the European Geosciences Union awarded him in 2010 the Jean Baptiste Lamarck Medal. He is Chair of the Geologic Time Scale Foundation and teaches courses in quantitative stratigraphy and the geologic time scale.

J.G. Ogg
JAMES OGG (Professor at Purdue University, Indiana, USA) was Secretary General of the International Commission on Stratigraphy (2000-2008), and is currently serving as coordinator of that ICS stratigraphy information service. His Mesozoic Stratigraphy Lab group works on aspects of climate cycles, magnetic polarity correlations and integration of stratigraphic information. Their TimeScale Creator array of visualization tools for extensive databases in global and regional Earth history was used to generate many of the diagrams in this book.

Mark D. Schmitz
MARK SCHMITZ is Professor of Geochemistry at Boise State University, Idaho, USA, and has extensive research interests in the development and application of radiogenic isotope geochemistry and high-precision U-Pb geochronology to problems of Earth systems evolution. He has been an active member of the Earth Time community and was co-editor and author for the Geologic Time Scale 2012. He seeks to enrich the radioisotopic calibration of the time scale through targeted dating of stratigraphically important volcanic event beds and the construction of robust chronostratigraphic models through geologic time. His extensive database with over 300 standardized radiogenic isotope ages (mainly U/Pb and Ar/Ar) is vital to this book.

GABI OGG applied micropaleontology to Jurassic-Cretaceous correlations before concentrating on public outreach in geosciences. She coordinated the extensive array of graphics in this book, and is the webmaster for the Geologic TimeScale Foundation (https://timescalefoundation.org) and for the TimeScale Creator visualization and database suites (https://timescalecreator.org). In addition to co-authoring the Concise Geologic TimeScale (GTS2016) and The Geologic Time Scale (GTS2012) books, she has produced numerous posters and time scale cards for public audiences.
