摘要:

A Nordic Union for research workers in the Quaternary has been founded during a meeting on the island of Öland in the Baltic and in the ‘Hall of the Union’ in the Royal Castle of Kalmar. The aim of the Union is to forward co‐operation between scientists inNorden(Denmark, Finlnnd, Iceland, Norway, and Sweden), especially by cncouraging larger rcsearch project, joint field cxcursions and symposia, and by studying educational and labour‐market

摘要:

Lodgement till and flow till are depositcd in quite different environments. In Weichselian depmits, they can be distinguishcd by the setting of the sediments, the fabric, geotechnical characters, and the morphological appearance. These indications support each other. Of the outlined methods, the morphological is the most convenient in practice. Since flow till normally exists together with meltwater sediments it is suggested that systematic morphological mapping will be time‐saving and most profitable for the prospecting of economically important clay, sand, and gravel deposit

摘要:

The investigation is based on diatem‐ and pollen analyses of a main profile from the ancient lagoon Barsebäcksmossen. The chronology is bared on C14‐‐dating.Seven transgressions are indicated, viz. 5200–4800 B.C., 4600–4400 R.C., 4150–3900 B.C., 3800–3700 B.C., 3600–3500 B.C., 3100–2950 H.C. and 2050–1850 B.C. Thc trangressions 4150–3900 B.C., 3800–3700 B.C. and 3600–3500 B.C. may only represent fluctuations during a ‘complex’ transgresssion. The transgresssion in Barsebäcksmtrssen are correlated with the transgresssion established by Berglund in the Baltic Sea and by Mörner in the Kattegatt sea.A change in the date of the pollen‐zone boundary AT 1/AT 2 from 4500

摘要:

The occurrence of seals in the Finnish prehistoric fauna and in the Baltic since the end of the last glaciation is discussed on the basis of subfossil remains in refuses at cultural sites, and stray finds. The species represented are the harp (Phoca groenlandicaMüller), the ringed seal (Phoca hispidaSchreb.), and the grey seal (Halicoerus grypus(Fabr.)), of which the latter two are native in the recent fauna, whereas the former has since become extinct in the Baltic. The earliest seals, which probably immigrated to the Yoldia Sea, were ringed seals, whereas the subfossil harp seals are solely found in sediments of the Litorina Sea stage

摘要:

14C‐dated percentage and absolute late‐glacial pollen diagrams from (1) Blelham Bog, north‐west England and (2) Cam Loch, north‐west Scotland arc subdivided into chronozones Bølling, Older Dryas, Allerød, and Younger Dryas as proposed for the Late‐Weichselian sequence by Mangerud et al.,Boreas3 (1974), with boundaries defined in conventional14C years. It is shown how these chronozone boundaries coincide in the two British pollen diagrams with boundaries between pollen assemblage zones which are interpreted as the results of environmental (climatic) changes. Differences between the pollen zones found in western Britain and those of the classic South Scandinavian profiles, which are interpreted as the consequence of regional differentiation in the vegetation of north‐west Europe circa 14,500 to 10,000 years ago, pose serious problems in the correlation of Late‐Weichselian and Late‐Devensian subdivisions on the basis of pollen assemblage zones, but a chronostratigraphical classification makes it possible to compare the Late‐Devensian profiles from western Britain with the Late‐Weichselian subdivisions of Mangerud et al., in which ‘chronozone boundaries seem to be climatically conditioned withi
