INTERNATIONAL CHRONOSTRATIGRAPHIC CHART
INTERNATIONAL CHRONOSTRATIGRAPHIC CHART. An interactive version of the International Chronostratigraphic Chart, based on its Semantic Web representation. For comments/issues and this visualisation's code, please see its Git Code Repository.
Versioned charts and detailed information on ratified GSSPs are available at the website http://www.stratigraphy.org. The URL to this chart is found below. Numerical ages are subject to revision and do not define units in the Phanerozoic and the Ediacaran; only GSSPs do.
International Commission on Stratigraphy (ICS) - IUGS
The primary objective of the International Commission on Stratigraphy (ICS) is to precisely define 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 …
Geologic Time Scale - Major Divisions of Geologic Time Chart
The chart shows major chronostratigraphic and geochronologic units. It reflects ratified unit names and boundary estimates from the International Commission on Stratigraphy (Ogg, 2009). Map symbols are in parentheses.
Chronostratigraphy - Wikipedia
Chronostratigraphy is the branch of stratigraphy that studies the ages of rock strata in relation to time. The ultimate aim of chronostratigraphy is to arrange the sequence of deposition and the time of deposition of all rocks within a geological region, and eventually, the …
International Chronostratigraphic Chart | icgc
The International Chronostratigraphic Chart describes the geological time in which the history of the Earth is inscribed. It combines a numerical scale that uses as a unit a million years (chronometric scale) and a scale in relative time units (chronostratigraphic scale).
Statigraphic subdivisions, numerical ages, Global Boundary Stratotype Section and Points (GSSP) and Global Standard Stratigraphic Ages (GSSA) are those provided on the 2022/02 version of International Chronostatigra-phic Chart drafted by K.M. Cohen, D.A.T Harper, P.L. Gibbard and N. Car International Commission on Stratigraphy, February 2022.
