This book was released on 2017-11-18 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Late Quaternary Sediments of Lake Michigan The maps revealed that the glaciolacustrine Equality Formation is dis continuous in Lake Michigan; however, in an area southwest of Grand Haven, Michigan, it displays a thickening that probably represents an offshore exten sion of the Allendale Delta of the glacial Grand River. The two lower members of the overlying Lake Michigan Formation are thickest in the deepwater basins of Lake Michigan. These lower members are composed of an extremely fine grained red glaciolacustrine clay deposited from suspension. In contrast, the upper three units of the Lake Michigan Formation are thickest in a belt along the eastern side of the lake and consist of gray clay resulting from erosion within the Lake Michigan drainage basin by waves and streams. A large influx of sediments from streams in western Michigan and possible redistribution of shoreline erosion debris by lake currents causes the accumulation of gray clay to be greatest on the eastern side of the lake.

Available in PDF, EPUB and Kindle. Book excerpt: Late Quaternary histories are investigated here for sediment cores from Lakes Huron and Michigan, using the oxygen- and carbon-isotope compositions of biogenic carbonates and the oxygen- and hydrogen-isotope compositions of porewater. Age models for these cores are based on sedimentological information, and where possible, radiocarbon and pollen dates. The Michigan Basin cores provide a thick record of the late Pleistocene, whereas the Huron Basin cores primarily record Holocene deposition. Taken together, the histories recorded in biogenic carbonates from these sediments provide a clear account of lakewater isotopic changes - and their significance - over much of the history of the Great Lakes Basin. Biogenic carbonates, and ostracodes in particular, serve as excellent recorders of lakewater!18O values. Modern specimens from Lake Huron have been used to assess non-equilibrium oxygen- and carbon-isotope fractionation effects during shell formation within this setting. This information provides improved ability to calculate the oxygenisotopic compositions of paleolakewater using fossil biogenic carbonates from the cores. The fossil shell compositions indicate intervals characterized by low!18O meltwater originating from the retreating Laurentide Ice Sheet and/or associated proglacial lakes, and periods dominated by higher!18O water that are more reflective of regional precipitation, runoff and climatic conditions. Differences in the oxygen- and carbonisotope compositions of deep- versus shallower-water ostracode species in the Michigan Basin cores suggest isotopic stratification of its lakewater during the late Pleistocene. Results for previously unstudied parts of the Huron Basin suggest that sub-basins acquired different oxygen-isotope compositions during periods of very low lake levels, reflecting different water sources and/or different conditions at such times. Early Holocene influxes of glacial meltwater into the Huron Basin, and to a lesser extent the Michigan Basin, correlate with major global climate perturbations that were likely triggered by release of large volumes of glacial meltwater into the Arctic and/or North Atlantic Oceans. Porewater did not preserve original lakewater!18O and!D values. These compositions are largely controlled by downward diffusion of modern lakewater.

Download or read book Quaternary Glaciation of the Great Lakes Region written by Alan Kehew and published by Geological Society of America. This book was released on 2018 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking advantage of new technological advances in Quaternary geology and geomorphology, this volume showcases new developments in glacial geology. Honoring the legacy of Frank Leverett and F.B. Taylor's 1915 USGS monograph of the region, this book includes 12 chapters that cover diverse topics ranging from hydrogeology, near-surface geophysics, geotectonics, and vertebrate paleontology to glacial geomorphology and glacial history. Several papers make use of detailed but nuanced shaded relief maps of digital elevation models of LiDAR data; these advances are brought into historical perspective by visiting the history of geologic mapping of Michigan. Looking forward, interpretations of the shaded relief maps evoke novel processes, such as regional evolution of subglacial and supraglacial drainage systems of receding glacial margins. The volume also includes assessment of chronological issues in light of greater accuracy and precision of radiocarbon dating of plant fossils using accelerator mass spectrometry versus older techniques.
Download or read book The Quaternary Period in the United States written by A.R. Gillespie and published by Elsevier. This book was released on 2003-12-17 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews advances in understanding of the past ca. two million years of Earth history - the Quaternary Period - in the United States. It begins with sections on ice and water - as glaciers, permafrost, oceans, rivers, lakes, and aquifers. Six chapters are devoted to the high-latitude Pleistocene ice sheets, to mountain glaciations of the western United States, and to permafrost studies. Other chapters discuss ice-age lakes, caves, sea-level fluctuations, and riverine landscapes. With a chapter on landscape evolution models, the book turns to essays on geologic processes. Two chapters discuss soils and their responses to climate, and wind-blown sediments. Two more describe volcanoes and earthquakes, and the use of Quaternary geology to understand the hazards they pose. The next part of the book is on plants and animals. Five chapters consider the Quaternary history of vegetation in the United States. Other chapters treat forcing functions and vegetation response at different spatial and temporal scales, the role of fire as a catalyst of vegetation change during rapid climate shifts, and the use of tree rings in inferring age and past hydroclimatic conditions. Three chapters address vertebrate paleontology and the extinctions of large mammals at the end of the last glaciation, beetle assemblages and the inferences they permit about past conditions, and the peopling of North America. A final chapter addresses the numerical modeling of Quaternary climates, and the role paleoclimatic studies and climatic modeling has in predicting future response of the Earth's climate system to the changes we have wrought.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available for download at: http://booksite.elsevier.com/9780444534477/ Completely updated detailed coverage of worldwide Quaternary glaciations Information in digital, uniformly prepared maps which can be used in a GIS such as ArcView or ArcGis Step-by-step guideline how to open and use ArcGis files Possibility to convert the shapefiles into GoogleEarth kmz-files Availability of chronological controls
