The AWG is a task group of the Subcommission on Quaternary Stratigraphy (SQS), a component body of the International Commission on Stratigraphy (ICS) that is responsible for maintaining and refining the International Chronostratigraphic Chart, which serves as the basis for the Geological Time Scale (GTS).Epoch data from the International Commission on Stratigraphy (v2022/10) Description. A dataset containing the boundary ages, abbreviations, and colors for the epochs of the Geologic Time Scale. Based on The ICS International Chronostratigraphic Chart (v2022/10), by Cohen, Finney, Gibbard, and Fan. Usage epochs Formatinternational chronostratigraphic chart on www.stratigraphy.org International Commission on Stratigraphy v 2014/02A geologic epoch is the fourth largest unit of time for the geologic time scale (Figure 1). Geologic epochs are also referred to as "series" (the chronostratigraphic name) or simply "epochs". Epochs tend to be 13 to 35 million of years in length. Epochs are subsections of longer periods and consist of groups of shorter ages.Epoch names are often "Upper", "Middle", or "Lower".

The definitions of chronostratigraphic units form the basis of the International Chronostratigraphic Chart (ICC) and standardize the geological time scale—e.g., when specific periods, epochs, and ages begin and end and how they can be identified in strata.Protocols established by the ICS to formalize chronostratigraphic units require the definition of a global …May 30, 2023 · Its primary objective is to define precisely global units (systems, series and stages) of the International Chronostratigraphic Chart that, in turn, are the basis for the units (periods, epochs and age) of the International Geological Time Scale; thus setting global standards for the fundamental scale for expressing the history of the Earth. ….
