 Publications: International Stratigraphic Chart Published
This edition of the chart, which was co-published with UNESCO, embodies the recent work of many Subcommissions of the IUGS International Commission on Stratigraphy (ICS) to define and standardize international stratigraphic nomenclature.
You may also download the International Stratigraphic Chart (3,147KB) to view it online or save it for off-line viewing or printing.
It gives a clear picture of the state of international stratigraphic nomenclature, including drawing clear distinctions between formal, semi-formal, and informal units, and between internationally approved and recommended chronostratigraphic units provisionally designated for international use.

 Quaternary
Some people do not recognize the Quaternary and consider it an informal term, included in the Neogene, as can be seen from the 2003 edition of the International Stratigraphic Chart, published by the International Commission on Stratigraphy.
An occasional alternative usage places the start of the Quaternary at the onset of North Pole glaciation approximately 3 million years ago and includes portions of the upper Pliocene.
The term Quaternary (fourth) was proposed by Jules Desnoyers in 1829 to address sediments of France's Seine Basin that seemed clearly to be younger than Tertiary Period rocks.

The lower Paleozoic comprises the Cambrian, Ordovician and Silurian {international stratigraphic chart, pdf file}.
These were deformed and metamorphosed during the Brabantian Deformation Phase, which possibly lasted from the Silurian to the Middle Devonian.
As such the Brabant Massif forms a distinct and compact unit.

However, this new version of the chart is more than a simple update of the first edition.
