Available in PDF, EPUB and Kindle. Book excerpt: Examination of fluvial deposits of the Late Cretaceous (Turonian) Ferron Sandstone Member, within the Mancos Shale Formation, in Central Utah (along Sweetwater Wash) was done to interpret fluvial style, characterize avulsion, and better constrain controls on channel-belt geometry. Cross sections were created based on measured sections and walking out beds, and showed two highly amalgamated sheet sands (Channel-belt A&C) separated by floodplain-encased channel-belts (isolated Channel-belt group B). The extensive sheet sandstones overlie distal floodplain deposits, and were subsequently characterized as regional avulsions. The isolated channel-belts overlie more proximal lacustrine and floodplain deposits, and were characterized as local avulsions. Detailed analysis of Channel-belt C showed a laterally extensive, unconfined channel-belt, formed by rivers 2.5-4 meters deep, with average storeys of 1.8 meters and bar lengths between 150-190 meters. Consistent paleo-current directions, evidence of downstream accretion, and a confluence zone, in highly scoured sheet-like deposits, suggest the deposition of Channel-belt C by a dominantly braided river. Correlation to a previously developed sequence stratigraphic framework showed that base level is an allocyclic control on alluvial architecture, with possible glacio-eustatic cycles controlling the regional stratigraphy. Channel-belt clusters were observed within the isolated channel-belts, but were not uniform across the basin, so they were interpreted as autocyclic or random, and not related to incised valleys below. Evidence for autocyclic controls, such as substrate erodability, was documented with laterally continuous indurated coals favoring extensive channel migration and the deposition of vi sheet sands. Sandy substrates favored channel reoccupation and vertical amalgamation. Comparing my data to net-to-gross models showed that the high net-to-gross and highly amalgamated deposits of the lower Channel-belt C are mainly associated with braided rivers, whereas meandering rivers are dominant in the low net-to-gross deposits of the isolated channel-belts; thus showing some similarities to previous net-to-gross models.

This book was released on 2019-01-22 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sinuous form and peculiar evolution of meandering rivers has long captured the imagination of people. Today, meandering rivers exist in some of the most densely populated areas in the World, where they provide environmental and economic wealth and opportunities, as well as posing hazards. Through geological time, the ancestors of these modern meanders built deposits that are now host to mineral resources, groundwater, and hydrocarbons. This Special Publication illustrates the breadth of current research on meandering rivers and their deposits. The collection of research papers demonstrates the state of science on fluvial process–product relationships. The articles cover fundamental and applied studies of both modern and ancient rivers, are based on state-of-the-art technology, include complementary philosophical approaches, and span a wide range of spatial and temporal scales. This book includes some of the most recent advances in the study of the morphodynamics and sedimentology of meandering rivers, and is an important resource for those who want to investigate fluvial systems and their deposits.

Download or read book The Geology of Fluvial Deposits written by Andrew D. Miall and published by Springer. This book was released on 2013-12-20 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluvial deposits represent the preserved record of one of the major nonmarine environ ments. They accumulate in large and small intermontane valleys, in the broad valleys of trunk rivers, in the wedges of alluvial fans flanking areas of uplift, in the outwash plains fronting melting glaciers, and in coastal plains. The nature of alluvial assemblages - their lithofacies composition, vertical stratigraphic record, and architecture - reflect an inter play of many processes, from the wandering of individual channels across a floodplain, to the long-term effects of uplift and subsidence. Fluvial deposits are a sensitive indicator of tectonic processes, and also carry subtle signatures of the climate at the time of deposition. They are the hosts for many petroleum and mineral deposits. This book is about all these subjects. The first part of the book, following a historical introduction, constructs the strati graphic framework of fluvial deposits, step by step, starting with lithofacies, combining these into architectural elements and other facies associations, and then showing how these, in turn, combine to represent distinctive fluvial styles. Next, the discussion turns to problems of correlation and the building of large-scale stratigraphic frameworks. These basin-scale constructions form the basis for a discussion of causes and processes, including autogenic processes of channel shifting and cyclicity, and the larger questions of allogenic (tectonic, eustatic, and climatic) sedimentary controls and the development of our ideas about nonmarine sequence stratigraphy.

Download or read book Geology and Geomorphology of Alluvial and Fluvial Fans written by D. Ventra and published by Geological Society of London. This book was released on 2018-07-04 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alluvial and fluvial fans are the most widespread depositional landform bordering the margins of highland regions and actively subsiding continental basins, across a broad spectrum of tectonic and climatic settings. They are significant to the local morphodynamics of mountain regions and also to the evolution of sediment-routing systems, affecting the propagation and preservation of stratigraphic signals of environmental change over vast areas. The volume presents case studies discussing the geology and geomorphology of alluvial and fluvial fans from both active systems and ancient ones preserved in the stratigraphic record. It brings together case studies from a range of continents, climatic and tectonic settings, some introducing innovative monitoring and analysis techniques, and it provides an overview of current debates in the field. This volume will be of particular interest to geologists, geomorphologists, sedimentologists and the general reader with an interest in Earth science.

This book was released on 2014-10-06 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Norwegian Continental Shelf (NCS), focus of this special publication, is a prolific hydrocarbon region and both exploration and production activity remains high to this day with a positive production outlook. A key element today and in the future is to couple technological developments to improving our understanding of specific geological situations. The theme of the publication reflects the immense efforts made by all industry operators and their academic partners on the NCS to understand in detail the structural setting, sedimentology and stratigraphy of the hydrocarbon bearing units and their source and seal. The papers cover a wide spectrum of depositional environments ranging from alluvial fans to deepwater fans, in almost every climate type from arid through humid to glacial, and in a variety of tectonic settings. Special attention is given to the integration of both analogue studies and process-based models with the insights gained from extensive subsurface datasets.

Download or read book The Characteristics and Development Technology Policy of Low Permeability Tight Sandstone Reservoirs in Fluvial Delta Systems written by Luo Chao and published by Scientific Research Publishing, Inc. USA. This book was released on 2024-04-23 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the study of low permeability and tight sandstone reservoirs within fluvial delta facies found in the Ordos Basin, Songliao Basin, and Sichuan Basin. It systematically examines the superimposed patterns, geometric forms, and scale characteristics of sedimentary sand bodies within the fluvial delta system. Additionally, it analyzes the impact of seepage barriers such as interlayers and closed faults on fluid flow. The book establishes a sedimentary model for sand bodies in typical sedimentary environments, considering the differences in separation and connectivity caused by the shape, scale, direction, and spatial overlap of different reservoir units and seepage barriers. It investigates the mechanisms of fluid flow controlled by interlayer, plane, and intralayer heterogeneity to understand the fluid flow within the reservoir architecture unit affected by different flow types.

This book was released on 2013-11-11 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Frontiers in Sedimentary Geology series was established for the student, the researcher, and the applied scientist to enhance their potential to stay abreast of the most recent ideas and developments and to become familiar with certain topics in the field of sedimentary geology. This series deals with subjects that are in the forefront of both scientific and economic interests. The treatment of a subject in an individual volume, therefore, should be a combina tion of topical, regional, and interdisciplinary approaches. The interdisciplinary aspects are becoming more and more important because most studies dealing with the natural sciences cannot effectively stand alone. Although this thrust may sound simple, in reality it is not, basi cally because each discipline has developed its own jargon and definitions ofterms. Communi cation among disciplines is a major issue and can be accomplished more constructively when people with different backgrounds join together at the same symposium and can read from the same volume rather than confining themselves within the world of their own specialty meetings and journals. Books in this series provide this connective link between disciplines. Each book in this series provides a continuous and connected flow of concepts throughout the volume by the use of introductory chapters that outline a topic to help the reader grasp its problems and to understand the contributions that follow.
