A Cromerian Complex palaeolake sediment sequence from the Zidini site, south-eastern Latvia

2013

Abstract This study is based upon palaeobotanical reinvestigation of the Pleistocene deposit strata revealed by test drillings in the buried valley at the Zidini site, southeastern Latvia. Up to 100 m thick lake sediment strata covered by three different till layers have been found in three 120–171 m deep test drillings. New palynological and plant macroremain analysis for sediment samples from core No. 43 have been done. These results and data from the earlier investigations at Zidini were compared. Clearer insights into depositional environment and vegetation change during the accumulation of sediments in the palaeolake have been acquired. According to recent studies and correlation of ob…

Upper Pleistocene biostratigraphy and traces of glaciotectonics at the Satiki site, western Latvia

2007

Structural, lithological, palynological and plant macroremain investigations of test-boring cores and gravel pit walls at the Satiki site suggest that gyttja and sandy gyttja units of basin sediments were deposited during the Felicianova (Eemian) Interglacial. A pollen diagram reflects the characteristic forest succession of the Eemian Interglacial: Betula, Pinus, Ulmus, Corylus, Quercus, Fraxinus, Tilia, Carpinus, Picea and Pinus. Forests of broadleaved trees and thermophilous plants dominated in the surroundings of the lake during the interglacial climatic optimum. The basin sediments contain a large number of warmth-demanding water plants such as Salvinia natans and Trapa sp. Paleobotani…
