Principles of Sedimentary Basin Analysis


Book Description

This book is intended as a practical handbook for those engaged in the task of analyzing the paleogeographic evolution of ancient sedimentary basins. The science of stratigraphy and sedimentology is central to such endeavors, but although several excellent textbooks on sedimentology have appeared in recent years little has been written about modern stratigraphic methods. Sedimentology textbooks tend to take a theoretical approach, building from physical and chemical theory and studies of mod ern environments. It is commonly difficult to apply this information to practical problems in ancient rocks, and very little guidance is given on methods of observation, mapping and interpretation. In this book theory is downplayed and the emphasis is on what a geologist can actually see in outcrops, well records, and cores, and what can be ob tained using geophysical techniques. A new approach is taken to stratigraphy, which attempts to explain the genesis of lithostratigraphic units and to de-emphasize the importance of formal description and nam ing. There are also sections explaining principles of facies analysis, basin mapping methods, depositional systems, and the study of basin thermal history, so important to the genesis of fuels and minerals. Lastly, an at tempt is made to tie everything together by considering basins in the con text of plate tectonics and eustatic sea level changes.




Paleocurrents and Basin Analysis


Book Description

In the past, interest in sedimentary structures has arisen mainly from the expectation that these features might be a guide to the environment of depo sition. But many sedimentary structures have also proved useful in determining stratigraphic order in nonfossiliferous, steeply inclined beds especially in Pre cambrian terranes. As the sequence problem has been reviewed at length by Shrock, it seemed to us, therefore, that the time is now ripe for a new look at sedimentary structures, not with respect to "top and bottom," but with reference to "fore and aft. " Much of the present-day interest in these structures stems from their usefulness in mapping of paleocurrents. A stage has been reached where there is need for a work which assembles, digests, and organizes our collective knowledge of the usefulness of directional properties of sediments and their application to basin analysis. This we have attempted to write. The desirability and need for such a book occurred to both of us independently. Upon discovering our mutual interest, we decided that a better book could be written by collaboration. Fortunately this collaboration became a reality because of support by the Guggenheim Foundation of one of us and the cooperation and support of The Johns Hopkins University of both of us. We acknowledge with thanks this indispensable aid.




Volcanic Successions Modern and Ancient


Book Description

One of our aims in the book is to provide geologists with a sound basis for making their own well founded interpretations. For that reason we cover not only concepts about processes, and the nature of the products, but also methods and approaches that may be useful in analysing both modern and ancient successions. Most importantly, we treat the diversity of products in volcanic terrains as facies, and we use the method of facies analysis and interpretation as a means of constructing facies models for different volcanic settings. These models will, we hope, be useful as norms for comparison for workers in ancient terrains. The idea for this book came into being between 1981 and 1982 when J. V. W. came to Monash University to take up a Monash Postdoctoral Fellowship. During this period a short course on facies analysis in modern and ancient successions was put together, integrating J.V.W.'s extensive volcanological experience in numerous modern volcanic terrains with R.A.F.C.'s extensive sedimentological and volcanological experience in older volcanic and associated sedimentary successions in the Palaeozoic and Precambrian of Australia. The enthusiastic response from the participants to the first short course, taught in May 1982, and to subsequent annual re-runs, encouraged us to develop the short course notes into this book. The idea for both the short course and the book arose because we felt that there was no single source available that comprehensively attempted to address the problems of analysing, interpreting and understanding the complexity of processes, products and stratigraphy in volcanic terrains.




Tectonic Controls and Signatures in Sedimentary Successions


Book Description

Stratigraphers and sedimentologists who are presently describing and interpreting the infill of sedimentary basins are generally agreed that it is difficult to disentangle the signatures of tectonic processes from those of climate and eustatic sea level change in the resultant rock succession. Until better criteria are developed to distinguish between the roles played by the major variables, it is still most useful to document and interpret basin-fill architectures where we know, from independent evidence, that one of the main controls is likely to have been a major contributor. This book contains a collection of papers describing situations where the tectonic setting is fairly well established, and it can be assumed that at least the tectonic factor has contributed to the resultant signatures.




Sedimentary Facies Analysis


Book Description

This book celebrates the professional career of Harold Reading, who has played a leading role in the development of the IAS, and has been at the roots of the development of 'facies sedimentology' as an art in itself and as a major tool in the broader field of geology. This special collection of original research papers from Harold Reading's students covers the wide range of his research interests and reflects the power of facies sedimentology today. State-of-the-art research papers in the important field of facies sedimentology * a festschrift to one of the great names in sedimentology.




Use of Discriminant Analysis for Classification of Strata in Sedimentary Successions


Book Description

The technique of instrumental neutron activation analysis (INAA) has been used to analyze chip samples of geological material for 12 elements. Discriminant analysis has been used to classify the unknown chip samples to the correct stratum in a sedimentary succession.




Sediment Provenance


Book Description

Sediment Provenance: Influences on Compositional Change from Source to Sink provides a thorough and inclusive overview that features data-based case studies on a broad range of dynamic aspects in sedimentary rock structure and deposition. Provenance data plays a critical role in a number of aspects of sedimentary rocks, including the assessment of palaeogeographic reconstructions, the constraints of lateral displacements in orogens, the characterization of crust which is no longer exposed, the mapping of depositional systems, sub-surface correlation, and in predicting reservoir quality. The provenance of fine-grained sediments—on a global scale—has been used to monitor crustal evolution, and sediment transport is paramount in considering restoration techniques for both watershed and river restoration. Transport is responsible for erosion, bank undercutting, sandbar formation, aggradation, gullying, and plugging, as well as bed form migration and generation of primary sedimentary structures. Additionally, the quest for reservoir quality in contemporary hydrocarbon exploration and extraction necessitates a deliberate focus on diagenesis. This book addresses all of these challenges and arms geoscientists with an all-in-one reference to sedimentary rocks, from source to deposition. Provides the latest data available on various aspects of sedimentary rocks from their source to deposition Features case studies throughout that illustrate new data and critical analyses of published data by some of the world’s most pre-eminent sedimentologists Includes more than 150 illustrations, photos, figures, and diagrams that underscore key concepts




From Depositional Systems to Sedimentary Successions on the Norwegian Continental Margin


Book Description

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.
