This paper reports the chronology as established by the uranium-series dating on a core drilled from Badwater Basin in Death Valley. To assess the source of uranium in these lacustrinedeposits, the AA. have also analyzed uranium and its isotopic
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
Sediment yield from glacio-lacustrine calcareous deposits during the postglacial period in the Combe d'Ain (Jura, France)
The middle valley of the river Ain (Jura) cuts through glacio-lacustrinedeposits laid down in an ice-dammed lake during the most recent glacial advance. The high values of sediment yield are ascribed to the amenability of glacio-lacustrinedeposits
The effect of glacial lacustrine relationships on the deposits of the Huron Lobe during Late Wisconsinian, south eastern Michigan in Moraines and varves. Origin/Genesis/Classification.
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

reported for two other calcareous formations that are exposed around several basins, documenting their difference in nature and origin with the deposits that are the main subject of this study. The results indicate that a lacustrine rather than purely
This report describes a mainly petrographical study of calcareous deposits that are associated with pan basins in eastern central Namibia, aimed at establishing the mode of development of this common type of formation. Some observations are also
pedogenic origin should also be considered for calcareous deposits that commonly occur along pan margins in other parts of southern Africa.
Deposits found in seasonal groundwater-fed lakes (turloughs) on the limestone lowland of Ireland were investigated, and of ninety turloughs surveyed, forty-six contained calcareous deposits known as marl, consisting of more than 60% calcium
carbonate. This paper discusses the origin and age of these deposits.
lacustrinedeposits. Morphological, lithological, deformational characteristics of these deposits and the drainage system of the area all suggest that the deposits were formed due to uplift and southward tilting of the Bozdağ horst. These deposits
This study investigates the origin and regional tectonic implications of high-altitude Plio-Quaternary fluvial deposits developed over the Bozdağ horst. A total of 23 deposits occur near the modern drainage divide comprising fluvial to occasionally
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

, and the mineralogical and geochemical characteristics of the deposited dust. Sediment supply to the lake source deposits involves fluvio-lacustrine transport of clays, with fluvial transport and salt weathering of silts and aeolian transport of sands. Subsequent aeolian
Harmettan dust deposition rates measured at Kano northern Nigeria during 1976-1979 range from 137 to 181 t/km/y. The characteristics and geomorphic history of the Chad Basin source deposits are inferred from the broad particle-size range
Opinions differ as to whether the true red clays mostly deposited on Upper Pannonian lacustrine sediments are dated as Pliocene or early Quaternary. Biostratigraphic and lithostratigraphic data show that these non-rewashed residual deposits of red
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
or mechanical sediment trapping systems, the sediment flux sensor records the time of deposition precisely and therefore is useful for investigating the linkages between external processes (hydrological) and sedimentation.
