The International Commission on Stratigraphy (ICS) has a long tradition of producing international charts that communicate higher-order divisions of geological time and actual knowledge on the absolute numerical ages of their boundaries. The primary objective of ICS is to define precisely a global standard set of time-correlative units (Systems, Series, and Stages) for stratigraphic ...PDF | Chronostratigraphy is both a set of stratigraphic concepts, and a set of guiding principles by which time represented in rocks, subdivides Earth's... | Find, read and cite all the research...The International Commission on Stratigraphy (ICS) has a long tradition of producing international charts that communicate higher-order divisions of geological time and actual knowledge on...INTERNATIONAL CHRONOSTRATIGRAPHIC CHART International Commission on Stratigraphy Colouring follows the Commission for the Geological Map of the World (www.ccgm.org) Chart drafted by K.M.

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".Except where otherwise noted, content on this site is licensed under a Creative Commons Attribution CC BY Licence.

This increasing simplicity is apparent, when the current ICC (Cohen et al. 2013 updated, based on Remane 2000) is compared with its antecedent, the GCC (Global Chronostratigraphic Chart) of Cowie and Bassett (1989) (Text-fig. 1a, b). This comparison, however, also reveals the absence in the ICC (Text-fig. 1b) of the previous ...
