Volcaniclastic Sedimentation in Lacustrine Settings


Book Description

This volume presents a unique compendium of papers assessing theeffects of volcanism on lakes, as recorded by the volcaniclasticsediments deposited within them. The unifying theme is that theeffects of volcanism on lacustrine sedimentation are diverse anddistinctive, and that volcaniclastic lacustrine sediments hold thekey to understanding a range of processes and events that cannot bereadily addressed by the study of any non-volcanic lakes. Thirteen papers, with authors from nine countries, examine bothmodern and ancient eruption-affected lacustrine deposits. Volcaniceruptions affect lakes and their deposits in many ways, and thesepapers evaluate processes and products of volcanic eruptions withinlakes, of tectonically impounded lakes strongly influenced byvolcanism, of eruption-impounded lakes and of general factorscontrolling sedimentation of vitric ash and pumice.Tephrastratigraphic studies also take advantage of the exceptionalpreservation of thin laminae in quiet lakes to precisely dateepisodes in the evolution of long-lived lakes and their catchmentareas, and to understand how volcanism affects normal lacustrineprocesses. The volume as a whole is an unparalleled source of informationon all aspects of the physical sedimentary results of volcanism inlacustrine settings, and serves as a complement to other studiesconcerned primarily with thermal and geochemical characteristics oflakes within volcanic craters.

Volcanic Processes in the Sedimentary Record


Book Description

Volcanoes and sedimentary systems are linked by a strong relationship. The ascent and eruption of magma liberates large volumes of material, through a variety of mechanisms, to the surrounding environment, with subsequent sediment input and transport influencing the evolution of that environment. This connection between volcanism and adjacent sedimentary systems has long attracted the attention of geologists, giving rise to an increasing body of academic research over the past three decades. Volcanic Processes in the Sedimentary Record: When Volcanoes Meet the Environment collects innovative works exploring how volcanoes and sedimentary systems interact, moving from the processes directly associated with eruptive behaviour, to the most distal sedimentary offshoots, where volcanogenic particles are accumulated during or after volcanic activity. In doing this, different volcanic and environmental settings are explored, travelling through space and time, showing how volcaniclastic detritus is produced and dispersed by volcanic, volcano-sedimentary and sedimentary mechanisms, via processes affecting development of volcanic edifices themselves through to the most distal depocentres.




Mechanism of Sedimentary Basin Formation


Book Description

This book is devoted to the mechanisms of sedimentary basin formation on active plate margins, which show enormous diversity reflecting complex tectonic processes. Multidisciplinary approach pursuing basin-forming mechanism is based on geology, sedimentology, geochronology and geophysics. Some chapters are dedicated to the genetic analysis of sedimentary basins in wrench deformation zones in forearc and intra-arc regions. Another block of chapters deals with basin formation in peripheral regions of Eurasia and intra-arc / foreland basins under the influence of the fluctuation of stress regimes. Finally geophysical approaches to basin analyses are shown in some chapters from microscopic to regional scales. Diverse contents of the chapters provide the audience with the present accomplishments of basin researches on active margins by Earth scientists.

Petrology of Sedimentary Rocks


Book Description

This textbook outlines the physical, chemical, and biologic properties of the major sedimentary rocks, as revealed by petrographic microscopy, geochemical techniques, and field study. It covers the mineralogy, chemistry, textures, and sedimentary structures that characterise sedimentary rocks, and relates these features to the depositional origin of the rocks and their subsequent alteration by diagenetic processes during burial. In addition to detailed sections on siliciclastic and carbonate rocks, it also discusses evaporites, cherts, iron-rich sedimentary rocks, phosphorites, and carbonaceous sedimentary rocks such as oil shales. This second edition maintains the comprehensive treatment of sedimentary petrography and petrology provided in the first edition, and has been updated with new concepts and cutting-edge techniques like cathodoluminescence imaging of sedimentary rocks and backscattered electron microscopy. It is ideal for advanced undergraduate and graduate courses in sedimentary petrology, and is a key reference for researchers and professional petroleum geoscientists.

Glacial Sedimentary Processes and Products


Book Description

Associating ice masses with the transport and deposition ofsediments has long formed a central theme in glaciology and glacialgeomorphology. The reason for this focus is clear, in that icemasses are responsible for much of the physical landscape whichcharacterizes the Earth's glaciated regions. This association alsoholds at a variety of scales, for example, from the grain-sizecharacteristics of small-scale moraines to the structuralarchitecture of large-scale, glacigenic sedimentary sequences inboth surface and subaqueous environments. This volume brings numerous state-of-the-art research contributionstogether, each relating to a different physical setting, spatialscale, process or investigative technique. The result is a diverseand interesting collection of papers by glaciologists, numericalmodellers and glacial geologists, which are all linked by the themeof investigating the relationships between the behaviour of icemasses and their resulting sedimentary sequences.




Analogue and Numerical Modelling of Sedimentary Systems


Book Description

Understanding basin-fill evolution and the origin of stratal architectures has traditionally been based on studies of outcrops, well and seismic data, studies of and inferences on qualitative geological processes, and to a lesser extent based on quantitative observations of modern and ancient sedimentary environments. Insight gained on the basis of these studies can increasingly be tested and extended through the application of numerical and analogue forward models. Present-day stratigraphic forward modelling follows two principle lines: 1) the deterministic process-based approach, ideally with resolution of the fundamental equations of fluid and sediment motion at all scales, and 2) the stochastic approach. The process-based approach leads to improved understanding of the dynamics (physics) of the system, increasing our predictive power of how systems evolve under various forcing conditions unless the system is highly non-linear and hence difficult or perhaps even impossible to predict. The stochastic approach is more direct, relatively simple, and useful for study of more complicated or less-well understood systems. Process-based models, more than stochastic ones, are directly limited by the diversity of temporal and spatial scales and the very incomplete knowledge of how processes operate and interact on the various scales. The papers included in this book demonstrate how cross-fertilization between traditional field studies and analogue and numerical forward modelling expands our understanding of Earth-surface systems.
