Unifying Cenozoic chronostratigraphy and geochronology: applying the rules

Newsletters on Stratigraphy, 2023
The International Chronostratigraphic Chart (ICC), as the basis of the International Geological Time Scale, is the primary product of the International Commission on Stratigraphy (ICS), itself the principal commission of the International Union of Geological Sciences (IUGS).

Tephrochronology and chronostratigraphy of the Miocene Chilcatay and Pisco formations (East Pisco Basin, Peru)

, 2020
Strata of Chilcatay and Pisco formations exposed in the Ica Desert (East Pisco Basin, southern Peru) preserve one of the most complete and rich records of Miocene marine vertebrates of the world. Despite its exceptional importance, the chronostratigraphy

Chronostratigraphy

2021
Chronostratigraphy is both a set of stratigraphic concepts, and a set of guiding principles by which time represented in rocks, subdivides Earth’s geological history. Chronostratigraphy is composed of a set of hierarchical stratigraphic units (i.e. System, Series, Stage, Substage and Chronozone for chronostratigraphic units) that are used to subdivide ...

High-precision U–Pb CA–ID–TIMS dating and chronostratigraphy of the dinosaur-rich Horseshoe Canyon Formation (Upper Cretaceous, Campanian–Maastrichtian), Red Deer River valley, Alberta, Canada

, 2020
The non-marine Horseshoe Canyon Formation (HCFm, southern Alberta) yields taxonomically diverse, late Campanian to middle Maastrichtian dinosaur assemblages that play a central role in documenting ...

Acritarchs from the Duolbagáisá Formation (Cambrian Series 2, Miaolingian) on the Digermulen Peninsula, Finnmark, Arctic Norway: towards a high-resolution Cambrian chronostratigraphy

Geological Magazine, 2020
New information on acritarchs from the Duolbagáisá Formation, Digermulen Peninsula, Arctic Norway, enable recognition of the three Cambrian Series 2 acritarch-based zones: the Skiagia ornata–Fimbriaglomerella membranacea, Heliosphaeridium dissimilare ...

The chronostratigraphy of the Anthropocene in southern Africa: Current status and potential

South African Journal of Geology, 2021
The process for the formal ratification of the proposed Anthropocene Epoch involves the identification of a globally isochronous stratigraphic signal to mark its starting point.

Chronostratigraphy and terrestrial palaeoclimatology of Berriasian–Hauterivian strata of the Cedar Mountain Formation, Utah, USA

Special Publications, 2019
This paper presents breakthroughs in the chronostratigraphy of the heretofore poorly constrained Yellow Cat Member of the Cedar Mountain Formation, which is an important record of terrestrial environments, ecosystems and global change in the ancient ...

Chronostratigraphy and Biostratigraphy

Geological Magazine, 1965
AbstractComments are given on a number of papers dealing with principles and procedure in stratigraphic classification which have appeared in British journals during 1963–65. It is emphasized that a clear distinction should be made between biostratigraphic units—bodies of rock strata characterized by certain palaeontological features and bounded by the

A history of chronostratigraphy

Stratigraphy, 2007
ABSTRACT Chronostratigraphy has a “prehistory” beginning with Leonardo’s and Steno’s twofold relative geologic time division. It developed further with Marsili’s (1728), Lehmann’s (1756), Arduino’s (1759-60) and Werner’s (1787) threefold, fourfold, and fivefold divisions respectively. Meanwhile, the initial steps were being taken in understanding Earth’
