Quaternary chronostratigraphy of south Spitsbergen

Polar Research, 1987
Recent detailed investigations of Quaternary sediments in south Spitsbergen enabled us to choose several key areas in this region (Lindner et al. 1984, 1986; Butrym et al. 1987). Samples collected in these areas were thermoluminescence and radiocarbon dated, and applied for a chronostratigraphic scheme of the Quaternary for this part of Svalbard (Fig ...

Quaternary Lives

Geologija, 2007
After a short-lived »ban«, the Quaternary has again been formalized as a chronostratigraphic unit, consisting of the Pleistocene and the Holocene.

Pliocene integrated chronostratigraphy from the Anno Formation, Awa Group, Boso Peninsula, central Japan, and its paleoceanographic implications

Progress in Earth and Planetary Science, 2019
The Pliocene climate is one of the best analogs for the climate of a globally warmer future. Here, we present a new Pliocene integrated chronostratigraphy from the Anno Formation in the uppermost Awa Group, which is distributed throughout the Boso ...

The ‘Anthropocene Proposal’: A Possible Quandary and A Work-Around

Quaternary, 2019
The debates about naming the unfolding times of anthropogenic global change the ‘Anthropocene’ are ultimately debates about the ‘human condition’.

Uppermost Albian biostratigraphy and chronostratigraphy

Carnets de Géologie, 2009

Constraining shifts in North Atlantic plate motions during the Palaeocene by U-Pb dating of Svalbard tephra layers

Scientific Reports, 2017
Radioisotopic dating of volcanic minerals is a powerful method for establishing absolute time constraints in sedimentary basins, which improves our understanding of the chronostratigraphy and evolution of basin processes.

Usolka section (southern Urals, Russia): a potential candidate for GSSP to define the base of the Gzhelian Stage in the global chronostratigraphic scale

Geologija, 2006
Conodont species Streptognathodus simulator Ellison, 1941 has been proposed recently to define the Kasimovian-Gzhelian boundary in the global chronostratigraphic scale.The species distributed globally and traditionally has been used as a marker of the ...

Chronostratigraphy and tectono‐sedimentary history of the Eastern South Pyrenean foreland basin (Ripoll Syncline, North‐East Spain)

The Depositional Record
This paper contributes to an understanding of the tectono‐sedimentary evolution of the South Pyrenean foreland system by reviewing the chronostratigraphic framework of the basin infill in its eastern sector. Six sections are analysed and cross‐correlated

Late Holocene Abrupt Changes in the Fluvial Dynamics of the Tiber Valley Catchment (Rome, Italy): An Impact of the 4.2 Event?

Quaternary
In the present work, we investigate the post-glacial aggradation of three tributary valleys draining the left hydrographic basin of the Tiber River in central Rome: the Murcia, Caffarella, and Grottaperfetta valleys.
