Download or read book Atlas of Submarine Glacial Landforms written by J.A. Dowdeswell and published by Geological Society of London. This book was released on 2016-12-16 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: New geophysical techniques (multibeam echo sounding and 3D seismics) have revolutionized high-resolution imaging of the modern seafloor and palaeo-shelf surfaces in Arctic and Antarctic waters, generating vast quantities of data and novel insights into sedimentary architecture and past environmental conditions. The Atlas of Submarine Glacial Landforms is a comprehensive and timely summary of the current state of knowledge of these high-latitude glacier-influenced systems. The Atlas presents over 180 contributions describing, illustrating and discussing the full variability of landforms found on the high-latitude glacier-influenced seafloor, from fjords and continental shelves to the continental slope, rise and deep-sea basins beyond. The distribution and geometry of these submarine landforms provide key information on past ice-sheet extent and the direction and nature of ice flow and dynamics. The papers discuss individual seafloor landforms, landform assemblages and entire landsystems from relatively mild to extreme glacimarine climatic settings and on timescales from the modern margins of tidewater glaciers, through Quaternary examples to ancient glaciations in the Late Ordovician.
Download or read book Glaciogenic Reservoirs and Hydrocarbon Systems written by M. Huuse and published by Geological Society of London. This book was released on 2012 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Glaciogenic reservoirs and hydrocarbon systems occur intermittently throughout the stratigraphic record, with particular prominence in Neoproterozoic, Late Ordovician, Permo-Carboniferous and Late Cenozoic strata. Recent interest in glaciogenic successions has been fuelled by hydrocarbon discoveries in ancient glaciogenic reservoirs in North Africa, the Middle East, Australia and South America. Glaciogenic deposits of Pleistocene age are noteworthy for their content of groundwater onshore and potentially prospective and/or hazardous gas accumulations offshore. The abundant imprints of Pleistocene glaciations in both hemispheres can be used to reconstruct complex histories of repeated ice cover and retreat, and glacier-bed interactions, thus informing our view on the dynamics of older ice caps and predictions of future glaciations. This volume aims to provide a better understanding of glaciogenic processes, their stratigraphic record and reservoir characteristics of glaciogenic deposits. The book comprises 3 overview papers and 16 original case studies of Neoproterozoic to Pleistocene successions on 6 continents and will be of interest to sedimentologists, glaciologists, geophysicists, hydrologists and petroleum geologists alike."-- P. 4 of cover.
Download or read book Geological Exploration in Murzuq Basin written by D. Worsley and published by Elsevier. This book was released on 2000-12-19 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Murzuq Basin is a large intracratonic sag basin located in southwestern Libya. Exploration efforts started in this vast and remote Saharan region already in 1957 and 60 exploratory wells have been drilled to date, resulting in over 20 discoveries with around 4,000 million barrels of oil in place. Most discoveries have been made in Ordovician sandstone reservoirs sourced by hot shales of the Lower Silurian Tanezzuft Formation. Oil is already being produced and exported from the area, but the basin's total hydrocarbon potential is still poorly understood. Recent exploration - especially the major discovery and initial development of the Giant "Elephant" Field - has greatly increased interest for the area's potential. Many petroleum geologists and companies now believe that the basin may well develop into a new major hydrocarbon province which will significantly contribute to Europe's energy needs in the next decades. This book presents papers from a conference held at Sebha University - on the eastern margins of the Murzug Basin - in September 1998.The book continues an ongoing series of presentations of the geology of Libya, but the 25 contributions herein mostly centre on the Murzuq Basin itself and on nearby areas. There are still many unresolved questions in terms of geological and hydrocarbon exploration in these difficult desert areas, but the papers herein will hopefully present a first comprehensive overview of an exciting frontier exploration region. About half of the papers are directly related to hydrocarbon exploration, and to source rock and reservoir development, but a wide variety of other features are also described, ranging from palaeontology and biostratigraphy to ore geology and water resources, covering the entire geological column from the Precambrian to the Holocene. The book concludes with a bibliography covering all geological aspects of this challenging but very promising frontier area.
Download or read book The Geology of Scotland 4th edition written by N. H. Trewin and published by Geological Society of London. This book was released on 2003-02-24 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 4th edition of The Geology of Scotland is greatly expanded from the previous edition with 34 authors contributing to 20 chapters. A new format has been adopted to provide a different perspective on the geology of Scotland. A brief introduction is followed by a chapter outlining some of the important historical aspects that in the 19th century placed Scottish geologists in the forefront of a new science. Scotland is constructed from a number of terranes that finally combined in roughly their present positions prior to about 410 million years ago. Thus the geology of each terrane is described up the time of amalgamation, providing chapters on the Southern Uplands, Midland Valley, Highlands, Grampian and Hebridean terranes. At the end of this section, a brief synthesis summarizes the events that resulted in the amalgamation of the various terranes into the present configuration. Traditional practice is followed in the description of the Old Red Sandstone, Carboniferous, Permo-Trias, Jurassic, Cretaceous, tertiary and Quaternary strata. A separate chapter covers Tertiary igneous rocks. An attempt is made to tell the story of the geological evolution of Scotland, rather than catalogue all areas and formations. Priority is given to the onshore geology, encouraging the reader to go into the field and visit some of the world-class geology on show in Scotland. The chapters are broadly-based, attempting to integrate the sedimentary and igneous histories, and summarize changes in palaeogeography and palaeoenvironments. Economic aspects are covered with chapters on Metalliferous Minerals, Bulk Resources, Coal and Hydrocarbons. A new departure is the chapter on aspects of Environmental Geology and sustainability. Additionally, this publication contains a colour section of 32 plates, illustrating aspects of Scottish Geology, as well as a coloured geological map of Scotland.
Download or read book European Glacial Landscapes written by David Palacios and published by Elsevier. This book was released on 2021-11-19 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: European Glacial Landscapes: Maximum Extent of Glaciations brings together relevant experts on the history of glaciers and their impact on the landscape of the main regions of Europe. In some regions the largest recorded glaciations occurred before the Last Glacial Cycle, in one of the major glacial cycles of the Middle Pleistocene. However, the best-preserved evidence of glaciation in the landscape is from the Last Glacial Cycle (Late Pleistocene). The book also analyses these older glacial landforms that can sometimes still be seen in the landscape today. This analysis provides a better understanding of the succession of Pleistocene glaciations and the intervening interglacial periods, examining their possible continental synchrony or asynchrony of past glacier behaviour. The result of this analysis gives important new insights and information on the origin and effects of climatic and geomorphological variability across Europe. European Glacial Landscapes: Maximum Extent of Glaciations examines the landscapes produced by glaciers throughout Europe, the geomorphological effects of glaciations, as well as the chronology and evolution of the past glaciers, with the aim of understanding the interrelationship between glacial expansion and climate changes on this continent. This book is a valuable tool for geographers, geologist, environmental scientists, researchers in physics and earth sciences. Provides a synthesis that highlights the main similarities or differences, through both space and time, during the maximum recorded expansions of Pleistocene glaciers in Europe Features research from experts in glacial geomorphology, palaeo-glaciology, palaeo-climatology and palaeo-oceanography on glacial expansion in Europe Includes detailed color figures and maps, providing a comprehensive comparison of the glacial landscapes of European Pleistocene glaciers

Download or read book Quaternary Evolution of the Drainage Systems in the Southern and Central North Sea Basin Deduced from High Resolution Reflection Seismic and Sedimentological Data written by Ayobami Abegunrin and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North Sea shelf is one of the classic regions for studying Quaternary depositional and erosional sedimentary structures formed by discharging melt-water from retreating ice sheets and fluvial processes during periglacial shelf exposure. This provides an avenue to unravel the complex interplay between shelf morphology, changes in hydrodynamic regime, sediment influx and climate-driven eustatic changes. The ongoing political energy transition has prompted an intense geo-survey and sampling of the North Sea floor largely by industrial organizations, various Federal agencies such as the German Federal Maritime and Hydrographic Agency (BSH), German Federal Institute for Geosciences and Natural Resources (BGR) as well as some scientific institutions. The wealth of acquired data in the course of these various commercial, governmental and scientific expeditions has led to an improved understanding of the Quaternary geology of the North Sea sub-surface. Using a combination of tidally corrected acoustic profiles, shallower and deeper sediment cores and cone penetration test (CPT) data acquired from the German North Sea sector, this doctoral thesis aimed at contributing to the ongoing understanding of the morphology, the development of the drainage systems and the palaeo-landscape of the North Sea shelf since the Last Glacial Maximum. It also aimed at refining the stratigraphy and the geotechnical properties of the highly competent shallow sand units in the southern North Sea. The study unraveled the evolution, morphology and valley infill successions of the Elbe Palaeovalley (EPV). The EPV, located in the southeastern North Sea, occur as a shallow geomorphological trough spanning a length of about 210 km and width of about 40 km. The valley base is about 65 m below the present day sea-level. During the Marine Isotope Stage 2 sea level lowstand, this SE-NW oriented palaeo-drainage evolved as a braided fluvial system in a periglacial environment. Seismo-stratigraphic interpretation of the EPV infill successions revealed five major units. During deglacial sea-level rise, the EPV evolved into an estuary with tributaries, intertidal and subtidal flats. Towards the western flank of the EPV, the Palaeo-Ems, one of the known major tributaries that fed the southern head of the EPV was also identified and its overall course was seismo-stratigraphically described. The Palaeo-Ems river course was mapped as a buried, low gradient and meandering channel branching into two major pathways as it approaches a newly discovered delta flat at the western flank of the EPV. In its downstream direction, the Palaeo-Ems formed a unified depositional system with the early phase of the EPV. Based on available data, this study also shed light on the Palaeo Ems/EPV morpho-stratigraphic relationship for the first time. Ongoing sea-level rise since the early Holocene overwhelmed the adaptation capabilities of the joint system leading to the drowning of the whole drainage system. By focusing on the less well understood, regionally dominant sand units which were deposited after the retreat of the last glaciers, this study also refined the stratigraphic units and geotechnical parameters of the uppermost 50 m below the sea floor within the German North Sea sector. Two sandy units, the Aeolian Member and the Upper Fluvial Member, were identified as dominant deposits in the late- to post-Saalian geology within the study area. In addition, a detail seismic analysis revealed the occurrence of a Saalian Buried Valley Member believed to comprise fluvial deposits. Based on the integration of seismic facies analysis with core and CPT data, a detailed geotechnical parameter set for each identified stratigraphic unit within the study area was developed and correlated with those of the neighboring North Sea sectors. The findings from this study complements and details Coughlan et al. (2018) geotechnical and stratigraphic framework of the study area as well as the stratigraphic framework recently developed by the BSH (2021). These deductions offer a new insight about the soil competency of the North Sea sub-surface which is key for various offshore commercial and economic activities within the region including but not limited to wind farm developments. The findings from this study are thus crucial contributions in understanding the dewatering system and subsequently, the reconstruction of the palaeo-landscape development in the German North Sea sector since the Last Glacial Maximum. Lastly, the study contributes to an improved geotechnical understanding of the stratigraphy of the North Sea.

This book was released on 2017-04-26 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quaternary Paleoenvironments examines the drowned landscapes exposed as extensive and attractive territory for prehistoric human settlement during the Ice Ages of the Pleistocene, when sea levels dropped to 120m-135m below their current levels. This volume provides an overview of the geological, geomorphological, climatic and sea-level history of the European continental shelf as a whole, as well as a series of detailed regional reviews for each of the major sea basins. The nature and variable attractions of the landscapes and resources available for human exploitation are examined, as are the conditions under which archaeological sites and landscape features are likely to have been preserved, destroyed or buried by sediment during sea-level rise. The authors also discuss the extent to which we can predict where to look for drowned landscapes with the greatest chance of success, with frequent reference to examples of preserved prehistoric sites in different submerged environments. Quaternary Paleoenvironments will be of interest to archaeologists, geologists, marine scientists, palaeoanthropologists, cultural heritage managers, geographers, and all those with an interest in the drowned landscapes of the continental shelf.
