Pollen and sediment stratigraphic analyses of a transect of core sequences are used to reconstruct Holocene lake-level changes in Lake Igelsjon, southern Sweden. The pattern of changes seen in the records is related to climatic/hydrological changes a

Fourteen lake basins on and west of Mt. Billingen have been analysed with respect to different stratigraphic methods: pollen, diatoms, other microfossils, 14C datings, lithology, grain-size distribution and chemical characteristics. The aim has been

The investigation is based on diatem- and pollen analyses of a main profile from the ancient lagoon Barsebacksmossen. The chronology is bared on C14--dating. Seven transgressions are indicated, viz. 5200–4800 B.C., 4600–4400 R.C., 4150–3900 B.C

basin. This period of balance between uplift and sea level rise was preceded by a relative uplift rate of 5 m/lW yr and followed by as high rates as 7-8 m/100 yr, possibly caused by a delayed uplift effect and perhaps also a local fall in sea level c

The deglaciation pattern at Mt. Billingen, within the Middle Swedish end moraine zone, and its relationship with dramatic water level changes in the Baltic Ice Lake is a classic topic of Swedish Quaternary Geology. Based on data west of Mt. Billingen

Holocene lake-level fluctuations in Lake Bysjon are reconstructed from recorded changes in the sediment limit and the content of reworked minerogenic matter in the sediment. These recorded changes are related to past lake-level fluctuations by correl

A study of past lake-level changes in Lake Xinias covering the last 40 000 years was presented in an earlier paper. In that paper, changes during the Holocene were only briefly dealt with, because of poor sedimentary representation. In this paper a s

The investigation of Lake Xinias, Greece, deals with lake-level changes since about 40 000 B.P. Particular effort was made to obtain a reconstruction of lake level during the Last Glacial Maximum, at about 18 000 B.P. The reconstruction was based on

A macrofossil-rich glaciomarine–marine–lacustrine sediment from a soft-water lake in southwestern Sweden has provided an opportunity to 14C date different components of its sediments. Bulk sediment dates are 100 to 500 yr older than fragile terre
