Quaternary geology of Sargent County, North Dakota
… general geologic history of the county for the Quaternary Period. </p><p> A geologic map of the county was prepared using field data, topo graphic maps, aerial stereopairs, and soil maps. A map showing surface sediment origin was subsequently made using the available field and laboratory …

Quaternary geology of the southern part of the Grand Forks and Bemidji quadrangles
<p>Northwestern Minnesota is an area at the southwestern edge of the Canadian Shield that is mantled by thick Pleistocene sediment. The Pleistocene material included a variety of glacial, shoreline, offshore, fluvial, and eolian sediment.</p> <p>The lithology of the glacial sediment reflects the …

The Evolution of the Profile Paradigm in the History of Pedology and Quaternary Geology: Concepts and Applications
… a region that has been studied closely by Quaternary geologists. The PWP subsolum contains a C horizon concept of more precisely defined scope than that traditionally used in pedology. In the traditional sense the interval between the solum and bedrock is designated as the C, whether …

Quaternary geology of the Campbellford, Trenton, Consecon, Tweed, Belleville, Wellington, Sydenham, Bath, and Yorkshire Island map-areas, Ontario /
Sediment relationships observed during geological mapping in southeastern Ontario indicate a relatively simple deglaciation history for the area during late Wisconsin time. The ice from the north (part of the Lake Simcoe lobe) and the Lake Ontario ice lobe, which were coalesced during most of late …

Quaternary geology and glacial history of the Haliburton region, south central Ontario, Canada: A model for glacial and proglacial sedimentation
The pattern of glacigenic sedimentation in the Haliburton region suggests that stagnation is an important element in the regional style of deglaciation in areas of moderate bedrock relief (50-150 m), such as the shield terrane of southern Ontario. The record of subglacial processes and sub-ice …

Quaternary geology of the German North Sea and Western Irish Sea Mud Belt: revised stratigraphies, geotechnical properties, sedimentology and anthropogenic impacts
The climatic development of the Mid to Late Quaternary (last 400,000 years) is characterised by fluctuation between glacial and interglacial periods leading to the present interglacial, the Holocene. In comparison to preceding periods it was believed the Holocene represented a time of relative …

Alluvial cycles and early agricultural settlement phases in the Jordan Valley
The parallel development of archaeology and Quaternary geology in several regions of the world is reviewed, and common problems in dating and correlating alluvial sequences are discussed. Buried archaeological remains and radiometric dates provide a chronological framework for the sequence of Late …

The Geologic and Archaeological History of the Dickie Carr Site 41PR26
… comparison is made with respect to the Late Quaternary geology of the upper Trinity River basin, Texas to interpret the geologic data. Two stratigraphic units were identified that record the Pleistocene-Holocene transition. The buried lower unit is comprised of terrace, floodplain, and …

Examination of the impact of the natural environment on levee sustainability, An
… include, amongst others, the configuration of Quaternary Geology with respect to the levee alignment, the hydrogeological nature of the alluvial aquifer beneath the levee, and soil physical properties. A binary logistic regression was then applied to the dataset to evaluate the correlation …

Pleistocene geology of the Grand Forks-Bemidji area, northwestern Minnesota
… is a report of a reconnaissance study of the Quaternary geology of an area in northwestern Minnesota. Surface geology was studied in an area extending from Grand Forks, North Dakota, in the northwest to Bemidji, Minnesota, in the southeast, an area of 10 723 square kilometres (4140 square …

Quaternary landscape evolution, pedology, and geoarchaeology in central Texas.
… Buttermilk Creek provides a view of late Quaternary landscape evolution in central Texas along a low-order tributary. The late Quaternary history of central Texas is a complex story of climate and hydrologic changes, sediment supply, and human interaction. From >60 ka near the transition …

Pollen analysis, chronology and palaeomagnetism of three Late Weichselian sites in southern Sweden
Three sites, Torreberga in Skåne, Farslycke in Blekinge and Lake Bolmen in Småland, with Late Weichselian lake sediments were studied with respect to pollen analysis and palaeomagnetism. The chronologies are based on pollen stratigraphical correlations, radiocarbon dating and, for two of the sites, …

Environmental and climatic aspects of the early to mid Holocene calcareous tufa and land mollusc fauna in southern Sweden
Although deposition of freshwater calcium carbonates, tufa, has occurred in large areas with carbonate soil or bedrock in Sweden, no tufa formation has been observed in Sweden. To better understand the factors controlling tufa formation in southern Sweden, bio- and lithostratigraphical studies were …

The Quaternary evolution of the mid-Norwegian continental margin
… reflection datasets are used to examine the Quaternary Naust Formation on the mid-Norwegian continental shelf and slope, both at a high level of detail and over a huge areal extent of over 150,000 km2. First, the analysis of broad-scale margin architecture demonstrates the gradual development …

Weichselian glaciations in the middle Notec River region, northwest Poland
This thesis presents results of studies on the ice flow pattern and ice movement mechanism during the Weichselian glaciations in the middle Notec River area, NW Poland. A new lithostratigraphy of the study area has been established, based on correlation of stratigraphical position, clast lithology, …

Quaternary stratigraphy of the Lake Sakakawea area, Mclean County, North Dakota
<p> The Quaternary stratigraphy of central North Dakota is best exposed along the nearly continuous, 20-meter-high, vertical bluffs of Lake Sakakawea in the Missouri River trench. The following lithostratigraphic units (in ascending order) are exposed just north of Riverdale, North Dakota, and can …
