The Anthropocene Working Group (AWG) is charged with this task as a component body of the Subcommission on Quaternary Stratigraphy (SQS) which is itself ...
The Anthropocene is a proposed geological epoch, and debates about whether it should be included in the geological time scale are ongoing. Some argue that the impact of humans is significant enough to warrant a separate epoch, while others argue that it is too early to add the Anthropocene to the geological time scale.One of the most widely used standard charts showing the relationships between the various intervals of geologic time is the International Chronostratigraphic Chart, which is maintained by the International Commission on Stratigraphy (ICS). Britannica Quiz.Mar 4, 2022 · The latest version of the International Chronostratigraphic Chart (2022/02) was published on on the International Commission on Stratigraphy (ICS). The chart (Fig.2) can be downloaded from the ICS’ website: For example, a spike in iridium levels laid down in rock strata across the planet roughly 66 million years ago aligned with the end of the reign of the dinosaurs.This was enough to convince geologists to close the chapter on a period known as the Cretaceous and open a new one called the Paleogene.
At the 34 th International Geological Congress, in 2012 in Brisbane, over 6000 delegates found the redesigned International Chronostratigraphic Chart of the International Commission on Stratigraphy (ICS) in their conference packages. The ICS Chart is a hierarchy of chronostratigraphic units (e.g. Systems, Series, andOf the more than 115 intervals of geologic time indicated on the International Chronostratigraphic Chart, 80 are associated with a specific physical site. ….

Abstract The proposal that the 'Anthropocene' should be ratified as a unit of the International Chronostratigraphic Chart/Geological Time Scale deserves serious consideration by the International Commission on Stratigraphy (ICS).
