Quaternary stratigraphy of Norden, a proposal for terminology and classification
TLDR
In this paper, a proposal for a common chronostratigraphical classification of the Quaternary in Norden (and partly continental NW Europe) is made, based on the sequence of glacials/interglacials.Abstract:
Principles and terminology for classification of the Quaternary are discussed, including lithostratigraphy, biostratigraphy. morphostratigraphy, climatostratigraphy and chronostratigraphy. The main conclusion is a proposal for a common chronostratigraphical classification of the Quaternary in Norden (and partly continental NW Europe). The Quaternary is subdivided into the Pleistocene and the Holocene Series. The Pleistocene is further subdivided into several provisional stages (Weichselian, Eemian, etc.), based on the sequence of glacials/interglacials. but with the boundaries preferably defined by stratotypes. The Late Weichselian and the Flandrian (Holocene) are subdivided into chronozoncs (Bolling, Older Dryas, Allerod, Younger Dryas, Preboreal, Boreal, Atlantic, Subboreal, Subatlantic) with the boundaries dcfined in conventional radiocarbon years.read more

TL;DR: In this article, stable isotope analyses performed on Lateglacial lacustrine calcareous deposits in The Netherlands provide a terrestrial oxygen-isotope record, comparable to that from the Greenland ice core.

Palaeoenvironmental changes inferred from malacofaunas in the Lateglacial and early Holocene fluvial sequence at Conty, northern France
TL;DR: In this article, the molluscan succession is put into a chronostratigraphic framework supported by numerous radiocarbon dates, and the authors reconstruct environmental changes from a Lateglacial and early Holocene sequence at Conty, northern France.

Late-glacial and holocene malacofaunas from archaeological sites in the Somme valley (North France)
TL;DR: The first malacological successions covering the Late-glacial period and the early Holocene are reported from archaeological sites in northern France as mentioned in this paper, which are related to the regional lithostratigraphy, Upper Palaeolithic/Mesolithic archaeology and to a radiocarbon chronology.

TL;DR: In this article, a box model of the Great Lakes is used to estimate meltwater flow into the North Atlantic between 8000 and 14,000 calendar years B.P. Controls on the model include the oxygen isotopic composition of meltwaters and lake waters as measured in the shells of ostracodes.

TL;DR: The Late Glacial in the Italian Alps and in the Po Plain: stratigraphy, vegeta- tion history and human peopling as mentioned in this paper is recon- structed on the base of high-resolution stratigraphic successions.

Half-life of Radiocarbon
TL;DR: The Fifth Radiocarbon Dating Conference, meeting at Cambridge (see p. 943 of this issue of Nature), adopted the following resolution as discussed by the authors, which determined the 1.1 − 3 of the half-life of carbon-14.

Late Quaternary foraminifera from Vendsyssel, Denmark and Sandnes, Norway
Abstract: Rolf W. Feyling-Hanssen: Weichselian interstadial Foraminifera from the Sandnes-Jæren area. Five shallow borings in the town of Sandnes, south of Stavanger, revealed clay deposits with marine fossils under a cover of sandy till with large blocks of Archaen rocks. This clay is called the Sandnes Clay. It is stiff and pre-consolidated, and disturbed only in the uppermost part. Four foraminiferal zones were distinguished, 1) the labradoricum-norcrossi assemblage, 2) the upper zone with scattered specimens, 3) the asklundi-bartletti assemblage, 4) the lower zone with scattered specimens. The assemblages are usually dominated by Elphidium clavatum and Cassidulina crassa, and turn out to be of Middle Weichselian (Middle Wisconsin) interstadial age. Deposits of corresponding age were found in the district of Jæren and on the island of Karmøy.

Radiocarbon dating of marine shells, including a discussion of apparent age of Recent shells from Norway
TL;DR: In this paper, the authors concluded that shell dates are reliable when handled carefully and gave apparent ages from 340±75 to 550±80 years, indicating that apparent age is not a significant problem in dating of Norwegian shells.
Late-glacial flora and periglacial phenomena in the Netherlands
TL;DR: In the East of Holland, in the Province of Overijssel, there is a region that, from the point of view of landscape, is one of the most beautiful and the most interesting we know in this country as discussed by the authors.
