Origin and stratigraphy of Holocene sediments, Souris and Des Lacs glacial-lake spillways, north-central North Dakota
… erosive. </p><p> This study is concerned with Holocene sediments that have filled the Souris and Des Lacs Valleys in Ward and Renville Counties. Most of the discussion is focused on the Souris Valley. Twelve cross sections were constructed from data gathered in the field, from the U.S. Army …

Stratigraphy and Site Formation at the Sanders Site (45 KT 315), Kittitas County, Washinton
… landform stability are marked by soil formation. Sediments preserved on-site appear to contain a relatively complete record of the Holocene, whereas across the creek at 45KT726, the earlier Holocene sediments have been stripped away by fluvial processes. Periods of landform stability and soil …

A multiproxy paleoenvironmental reconstruction of Late Quaternary marine sediments: Sunda Shelf, Southern South China Sea
… material) indicated the nearshore core was Holocene (ca. 10,000-6,000 cal years BP) in age while the offshore core was deposited prior to the last glacial maximum (ca. 45,000 cal years BP and possibly older) during marine isotope stage (MIS) 3 (ca. 60,000 - 30,000 yrs BP) within the late …

The response of wetlands to sea level rise: Ecologic, paleoecologic, and taphonomic models
… rise may be similar to trends interpreted from Holocene sediments, a paleoecologic analysis of wetland peats may provide a predictive model for wetland succession. Three areas of focus are necessary to achieve predictive power, however: ecologic, sedimentalogic, and taphonomic. No single …

Palaeoenvironmental reconstruction in South Africa's year-round rainfall zone using multiproxy geochemical analyses on lake sediments from Swartvlei
… lakes in the south coast of South Africa contain sediments with good records of palaeoenvironmental changes. Swartvlei is the largest of the lakes in the Wilderness Embayment and is connected to the Indian Ocean via an estuary. The lake is believed to have been formed during sea-level regressions …

Siesmic Stratigraphy of Upper Pleistocene gravel and holocene mudbelt deposits between wreck point and the kamma river on the western shelf of South Africa
… of the deposition of Quaternary and Holocene sediments along the west coast of Southern Africa between Wreck Point at approximately 28º50.00′S and the Kamma River at approximately 29º20.00′S, based primarily on seismic stratigraphy. The high resolution airgun seismic survey performed …

Massenbilanzen holozäner Sedimente am südlichen und mittleren Oberrhein
Die vorliegenden Arbeit befasst sich mit den holozänen Sedimenten, die seit Beginn des Ackerbaus vor etwa 7500 Jahren im südlichen Oberrheintiefland in Form von Auenlehmen und Kolluvien abgelagert wurden. Ziel war es, diese Sedimente in ihrer räumlichen Ausdehnung und Mächtigkeit zu erfassen und …

Investigating sediment size distributions and size-specific Sm-Nd isotopes as paleoceanographic proxy in the North Atlantic Ocean: reconstructing past deep-sea current speeds since Last Glacial Maximum
To explore whether the dispersion of sediments in the North Atlantic can be related to modern and past Atlantic Meridional Overturning Circulation (AMOC) flow speed, particle size distributions (weight%, Sortable Silt mean grain size) and grain-size separated (0–4, 4–10, 10–20, 20–30, 30–40 and …

Late glacial and Holocene marine geology, palaeoceanography and palaeoecology of the Northern Isles of Scotland
… in which human populations develop. During the Holocene, much of the northwestern North Sea has experienced low sediment accumulation rates, inhibiting the investigation regional palaeoenvironmental change using traditional marine sediment proxies. However, on the DY150 research cruise (2022), …

The geologic history of Lake of the Woods, Minnesota, reconstructed using seismic-reflection imaging and sediment core analysis
… of the best-preserved sequences of Lake Agassiz sediments are found in remnant lake basins where erosional processes are less pronounced than in adjacent higher-elevation regions. Lake of the Woods (LOTW), Minnesota, is among the largest of the Lake Agassiz remnant lakes and is an ideal location …
