A paleomagnetic record for the Grande Pile lacustrine sequence deposited during the last interglacial-glacial cycle has been constructed based on continuous sampling of a 15-m-long oriented core (GPXX). The present work is intended to assess
A complex interglacial sequence of lacustrine sediments has been found near the village of Turbuta in NW Romania. Mollusk, plant macrofossil, and pollen analyses reflect climatic and environmental changes around the last interglacial climatic
Here the AA. report the preliminary results of Cs 137 measurements on the lacustrine sediments of Dalian Lake, Qinghai Province, China. The objectives were to determine sediment accumulation rates and trace environmental changes in the surrounding

The aim of this study is to characterize the response of a lacustrine multiple-barred nearshore to a sequence of storm and non-storm events at the intermediate scale. The feedback mechanisms between the pre-existing morphology and the wave forcing
are identified and the consequence of those feedbacks to the behaviour of the nearshore environment over a sequence of storm events is explored at Burley Beach on the southeastern shore of Lake Huron, over the ice-free season of 2001/2002.

A design for a sediment flux sensor is provided for use in sedimentation studies in lacustrine and shallow marine environments. The sensor utilizes an optical system to measure sediment accumulation with a data logger. Unlike other passive
Physicochemical, mineralogical, and geochemical characteristics of lacustrine sediments of the Konya Basin, Turkey, and their significance in relation to climatic change
Physicochemical, mineralogical, and geochemical characteristics of 279 highly calcareous lacustrine sediment samples obtained from a 30 m drilling core in the western part of the Great Konya Basin, Turkey were studied. The results suggest
that gypsum-rich layers were formed under shallow, saline waters, possibly associated with warm to hot and dry environments such as the Last Interglacial epoch and the early Holocene. The sediments characterized by relatively high amounts of non-salt sediments
, in which gypsum did not accumulate, could be deeper water phases formed under the cold and/or wet environments such as the glacial epochs.
The physical settings of the rhythmite exposures in the Peshawar basin are discussed herein and evidence is presented that supports the hypothesis that these sediments were deposited as a result of periodic catastrophic floods, not lacustrine
Quatre sous-environnements distincts de dépôt de travertins et de stromatolites fossilifères sont identifiés dans trois bassins lacustres de haute altitude (El Peinado, Las Coladas et Las Peladas), dans l'Altiplano andain sud, au nord-ouest de
Le bassin lacustre d'Acerno est un paléolac tectonique qui s'est formé dans les Apennins du sud au début du Pléistocène moyen. L'analyse pollinique réalisée sur la séquence lacustre (environ 100 m) a permis de reconstituer l'histoire de la
The objective of this paper is to study the vegetation history of southern Chocó from a C 14 dated lacustrine sediment record to obtain a first impression of the environmental history of this ecosystem.
The AA. examine evidence for climatic change at the Aubrey Clovis site, north-central Texas, over the past 14,000 yr. The primary emphasis of this paper will be on stable isotopic evidence from pedogenic and lacustrine carbonates from the study site
