The ICS International Chronostratigraphic Chart

  title={The ICS International Chronostratigraphic Chart},
  author={Kim M. Cohen and Stanley C. Finney and Philip L. Gibbard and Junxuan Fan},
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 successions worldwide. These units are, in turn, the basis for the Periods, Epochs and Ages of the Geological… 

Global chronostratigraphical correlation table for the last 2.7 million years, version 2019 QI-500

The table provides a correlation of chronostratigraphical subdivisions of late Cenozoic geological time, spanning the last 2.7 million years. The formal division of the Quaternary is the

Partitioning the Quaternary

Ordovician integrative stratigraphy and timescale of China

In this chapter, starting with a brief review of the research history and current status in the studies of the Ordovician chronostratigraphy in China, the subdivision of the Ordovician System,

The Geological Society of America Geologic Time Scale

The Geological Society of America has sponsored versions of the geologic time scale since 1983. Over the past 30 years, the Geological Society of America Geologic Time Scale has undergone substantial

Ice-volume-forced erosion of the Chinese Loess Plateau global Quaternary stratotype site

The International Commission on Stratigraphy (ICS) utilises benchmark chronostratigraphies to divide geologic time. The reliability of these records is fundamental to understand past global change.

Ice-volume-forced erosion of the Chinese Loess Plateau global Quaternary stratotype site

It is shown that the interpretation of a benchmark archive in China has been inaccurate, and that ice volume primarily controls desert dynamics, sediment preservation, and precipitation at the site, which demonstrates the dominant influence of ice volume on desert expansion, dust dynamics and sediment preservation.

Cyclostratigraphy, stratigraphic gaps and the duration of the Hettangian Stage (Jurassic): insights from the Blue Lias Formation of southern Britain

Abstract The lithostratigraphic characteristics of the iconic Blue Lias Formation of southern Britain are influenced by sedimentation rates and stratigraphic gaps. Evidence for regular sedimentary

The contribution of fossils to chronostratigraphy, 150 years after Albert Oppel

The 150th anniversary of the death of Albert Oppel (1831–65) provided the opportunity to celebrate this outstanding stratigrapher with a Thematic Issue dedicated to the importance of fossils for

A new stratigraphic framework for the Miocene – Lower Pliocene deposits offshore Scandinavia: A multiscale approach

Here, we present an updated stratigraphic subdivision of the Oligocene to Pleistocene succession (880–610 m) in the newly proposed type well for the Molo Formation, the industrial 6407/9‐5 well,

The reality of GSSPs

  • S. Finney
  • Environmental Science, Geography
  • 2013
The proposal that chronostratigraphic and geochronologic units are un-necessary and confusing is based on a mistaken concept of GSSPs. Each GSSP does represent a specific point in time, and two

Inauguration of the GSSP for the Jurassic System

  • Environmental Science, Geography
  • 2012
Formal definition of the Triassic-Jurassic boundary at a Global Stratotype Section and Point (GSSP) for the base of the Jurassic System proved to be difficult because of several geological factors.

International Stratigraphic Guide: A Guide to Stratigraphic Classification, Terminology, and Procedure

This reprint of the 1994 volume was produced at the request of the IUGS International Commission on Stratigraphy and updated and expanded the discussions, suggestions, and recommendations of the first edition, expansions necessitated by the growth and progress of stratigraphic ideas and the development of new Stratigraphic procedures since release of thefirst edition.

Quantitative radiometric and biostratigraphic calibration of the Pennsylvanian–Early Permian (Cisuralian) time scale and pan-Euramerican chronostratigraphic correlation

A quantitative biostratigraphic and radiometric calibration is presented for the Pennsylvanian through Early Permian global time scale, based upon high-precision, isotope dilution–thermal ionization

The Geological Time-Scale

RECENTLY Dr. K. I. Mayne, Dr. R. St. J. Lambert and D. York1 proposed an extended geological time-scale which would place the middle of the Upper Cambrian at about 650 million years ago compared with

Calibrating the End-Permian Mass Extinction

High-precision geochronologic dating constrains probable causes of Earth's largest mass extinction and reveals that the extinction peak occurred just before 252.28 ± 0.08 million years ago, after a decline of 2 per mil (‰) in δ13C over 90,000 years, and coincided with a δ 13C excursion that is estimated to have lasted ≤20,000 Years.

Summary Twelve rocks for which calculated isotopic ages are mutually consistent and for which there is some biostratigraphic control have been used in the construction of a Permian time-scale. On the

The Global Boundary Stratotype Section and Point (GSSP) of the Carnian Stage (Late Triassic) at Prati di Stuores/Stuores Wiesen Section (Southern Alps, NE Italy)

The Global boundary Stratotype Section and Point (GSSP) for the base of the Carnian Stage (Late Triassic) is defined on the north flank of the Cordevole Valley, on the southern slopes of the crest

The global stratotype sections and points for the bases of the Selandian (Middle Paleocene) and Thanetian (Upper Paleocene) stages have been defined in the coastal cliff along the Itzurun Beach at
