Willapa Bay, a coastal plain estuary, contains extensive tidal flats cut by channels and distributaries. Well-sorted fine sand occurs throughout the bay, with increasing amounts of silt- and clay-size sediment present on the tidal flats near the sourht end of the bay and adjacent to the mouths of rivers flowing into the bay. The channels are generally scored of this fine sediment by strong bottom currents. Organic carbon and organic nitrogen contents increased with decreasing mean grain-size, and the ratio of carbon to nitrogen revealed two types of organic matter in the bay. One type, associated with the fine-grained sediment on the tidal flats, had an average ratio of 13.8; the other type, associated with the coarser channel sediments, had an average ratio of 6.1. At the bay entrance a littoral drift to the north results in extensive shoaling north of Leadbetter Point and erosion on Cape Shoalwater. A southward migration of the channel through the tidal delta off the bay entrance indicates a littoral drift to the south in this area. Spits and shoals forming inside the bay entrance are a result of a net influx of fine sand into the bay from the eroding cape. The distribution of brackish-water to marine suites of Foraminifera is closely related to the sedimentary environments in the bay. Heavy minerals indicate source areas for the sediment from the Columbia River drainage basin as well as the Willapa Bay drainage basin. Fine sand on the tidal flats east of Long Beach Peninsula is a relict of the growth of the spit. (Author).

Integration of ichnological information into sedimentological models, and vice versa, is one of the main means by which we can improve our understanding of ancient depositional environments. Mainly intended for sedimentologists, this book aims to make ichnological methods as part of facies interpretation more popular, providing an analytical review of the ichnology of all major depositional environments and the use of ichnology in biostratigraphic and sequence stratigraphic analysis. It starts with an introduction to the historical aspect of ichnology, introducing common concepts and methods, and then continues with parts treating the main depositional systems from continental, shallow-marine and deep-marine siliciclastics, and marine carbonates. The last part is dedicated to the ichnology in hydrocarbon reservoir and aquifer characterization. First overview in 25 years of the status of ichnological studies in facies reconstructions of all major depositional environments Written by a selected, well-experienced and specialized international authorship Provides easy access to the comprehensive and widespread literature

This IAS Special Publication contains 23 papers presented at the 3rd International Research Symposium on Modern and Ancient Clastic Tidal Deposits. This symposium series has an enviable international reputation for its quality, and so the contributions represent the latest developments in the field. The conference was preceded and followed by a number of field trips to some of the most prominent tidal flat and barrier island systems of continental Europe, and these have been written up as overview papers that summarize the current state of knowledge about these various tidal regions. The latest research results from this very specialized field.

A three-day Symposium on Clastic Tidal Deposits was organlzed In Utrecht in August 1985, and attended by about 200 participants. Durlng the meeting some 60 papers and 25 posters were presented, while simultaneously workshops on varlous topics were held. The meeting was generously sponsored by the International Asso ciation of Sedimentologists, the Royal Dutch I Shell Exploration and Productlon Laboratories, Brltish Petroleum Company, Chevron Oil Company, and K.L.M. This volume contalns extended versions of papers that were presented durlng the meeting, papers reporting about items studied durlng the excursions, and, more over, several contributions which were soliclted after the conference In order to make the volume more representative. As in most fields of sedimentological research, the comparlson of recent processes and products with ancient counterparts and vlce versa is important for under standing the full sequence of processes and events that lead to the final end product of tide-influenced sedimentary environments. In this respect we are happy that recent as weil as fossil sediments get ample attention. Research on tidal sedimentary processes and products has tradltionally put much emphasis on siliciclastic sediments. Still, carbonate and mixed carbonate/silici clastic sediments, though being subject to tidal influences in many places, receive little· attention in this respect, which, we regret; is also reflected In this volume.

Tidal deposits have been a specific research topic for about 40 years, and whilst this has resulted in a proliferation of papers in scientific journals, there have only been a few book-length syntheses. Over the years, tidal sedimentology has been reinforced by fluid mechanics and numerical modelling but has remained rooted in facies and stratigraphic studies. Recent developments in tidal sedimentology lean toward a more quantitative assessment of the imprint of tides in the facies record of intertidal and shallow subtidal areas. They highlight the increasing relevance of tidal deposits studies, from high resolution subsurface reservoir geology to climate change and sea-level rise. This volume gathers 17 contributions to the Tidalites 2012 congress held in Caen, France. It reflects current advances in the sedimentology and stratigraphy of tidal deposits, in both ancient and modern environments. It shows the current diversity of this field of research, through a wide spectrum of methods including remote sensing, in-situ hydrodynamical measurements, and ichnology, in addition to classic field studies and petrography.

The book is structured thematically, encompassing principles, processes and products, practice and applications. Discussion of processes that control heavy mineral assemblages throughout the rock cycle are presented by leading experts, whose key-note works are followed by specialist case studies. Each work also provides details on the geology of the study area, techniques and data treatment. The high number of contributions represent the collective experience and wisdom of generations of geologists, and provide an invaluable source of references to works carried out in many parts of the world. * Presents a unique and authoritative resource of immediate relevance and practical use to the researcher and applied geologist * Contains case studies demonstrating the broad range of applications of heavy minerals in a variety of modern and ancient geological settings, and in resource exploration * Includes examples of geological problems from employing heavy mineral analysis and establishing criteria that can be applied before deciding to undertake a study

This book presents a comprehensive, contemporary review of tidal environments and deposits. Individual chapters, each written by world-class experts, cover the full spectrum of coastal, shallow-marine and even deep-marine settings where tidal action influences or controls sediment movement and deposition. Both siliciclastic and carbonate deposits are covered. Various chapters examine the dynamics of sediment transport by tides, and the morphodynamics of tidal systems. Several chapters explore the occurrence of tidal deposits in the stratigraphic context of entire sedimentary basins. This book is essential reading for both coastal geologists and managers, and geologists interested in extracting hydrocarbons from complex tidal successions.
