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

Landslide Fens as a Sensitive Indicator of Paleoenvironmental Changes Since the Late Glacial: A Case Study of the Polish Western Carpathians
TL;DR: In this article, the authors reconstructed and interpreted the paleoenvironmental changes recorded in landslide fen sediments using multiproxy analysis of the sequences using pollen, lithological (loss on ignition, grain size and petrography) analyses of samples accurately dated by numerous radiocarbon (14C) dates.

TL;DR: In this paper, the authors reconstruct patterns of ice flow and retreat of the southwestern Scandinavian Ice Sheet, from 2900 field observations of glacial striae and elevation measurements of 60 ice-marginal-deltas from a high-resolution LiDAR DEM.

Geomagnetic variations recorded in Older (? 23 000 B.P.) and Younger Yoldia Clay (? 14 000 B.P.) at Nørre Lyngby, Denmark
TL;DR: In this paper, the authors present detailed palaeomagnetic results from a rapidly deposited 12.5m Younger Yoldziz Clay sequence of age around 14000 B.P. at the coast cliff at N$rre Lyngby (northern Jutland, Denmark) and a 2m Older Yoldia Clay sequence with age between 23 000 and 40 000 B.p.

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.
