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 ...

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’

Weichselian chronostratigraphy and correlations

Boreas, 1981
The glacial history of the Fennoscandian ice cap beyond some 20,000 years B.P. is fairly poorly known because of the absence of a reliable dating control. The Eemian Interglacial of Europe is not dated at all. The Weichselian Glaciation seems to be characterized by three main glaciation maxima separated by two main interstadial periods (of quite ...

Permian chronostratigraphy in Kansas

Geology, 1990
Correlations between the type Permian System of Russia and North American strata have been difficult for decades because of biostratigraphic and nomenclatural confusion. Consequently, a standard Permian section was established in west Texas that is widely accepted throughout North America. Series of the North American standard section are, in ascending

Chronostratigraphy beyond the GSSP

Stratigraphy, 2007
The introduction of the GSSP concept has been successful to the extent that it has fostered a considerable amount of stratigraphic studies. It has also led to a re-thinking of stratigraphic principles and practices. Chronostratigraphy as practiced today attempts to reconcile two opposite philosophical principles, the rock-time model of Hedberg and the ...

Chronostratigraphy of Upper Eocene Microspherules

PALAIOS, 1989
Impact-glass microspherules occur at numerous localities in rocks that can be dated as late Eocene. There is debate as to whether the discovered microspherule layers are the result of two or three impact events. Standard biostratigraphic techniques have been employed to date the microspherule layers.
