Description : The stratigraphic concept of a depositional sequence was introduced to the scientific literature by Peter Vail and his colleagues in the late 70s, building on the shoulders of giants like Chamberlain, Sloss and Wheeler. Since then, several papers compared and contrasted the original sequence-stratigraphic school published in the AAPG Memoir 26 in 1977 with other approaches to subdivide the geologic record, as well as, debating the model validity and impact on the community. At its core, the "model" is really a stratigraphic interpretation method, which was never explicitly documented in the literature. The objective of this book is to present the sequence stratigraphic method in its current form in an attempt to clarify its usage and application in diverse geologic data and depositional environments. This publication is the result of more than 3 decades of sequence stratigraphy research and application. The objective is to emphasize the most important aspects of Sequence Stratigraphy-a method to guide geologic interpretation of stratigraphic data (seismic profiles, well-logs, cores and outcrops) across scales (from local to regional and global) and depositional environments (from continental to deep marine). This book in an 11 x 17 format is designed to be easily used for teaching or self-learning experiences. In the second edition of the "Atlas", the book was divided in 2 volumes-Exercises and Solutions-to make it easier to use the publication as text book for sequence stratigraphy courses in universities. Also, a new exercise was added and several of the existing exercises went through major updating and editing.

Description : Sequence stratigraphy has experienced a virtual explosion of applications in recent years. During that time, the concepts upon which sequence stratigraphy is based have been evolving to conform to new observations as well as new types of data. This volume summarizes the current status of this discipline as it applies to siliciclastic deposits. Its emphasis is on sequence stratigraphy as an 'approach' to geological analysis, rather than as a model to which all data sets must conform.

Description : The stratigraphic concept of a depositional sequence was introduced to the scientific literature by Exxon Production Research Company (EPRco) in the late 70s, building on the shoulders of giants like Chamberlain, Sloss and Wheeler. Since then, several papers compared and contrasted the original Exxon (and later, ExxonMobil) sequence/stratigraphic school with other approaches to subdivide the geologic record, as well as, debating the ExxonMobil model validity and impact on the community. At its core, the ExxonMobil geomodel is really a stratigraphic interpretation method, which was never explicitly documented in the literature. The objective of this book is to present the ExxonMobil sequence stratigraphic method in its current form in an attempt to clarify its usage and application in diverse geologic data and depositional environments. This publication is the result of more than 3 decades of Sequence Stratigraphy research and application at EPRco and at the ExxonMobil Upstream Research Company (URC).

Description : Sequence stratigraphy is a powerful tool for the prediction of depositional porosity and permeability, but does not account for the impact of diagenesis on these reservoir parameters. Therefore, integrating diagenesis and sequence stratigraphy can provide a better way of predicting reservoir quality. This special publication consists of 19 papers (reviews and case studies) exploring different aspects of the integration of diagenesis and sequence stratigraphy in carbonate, siliciclastic, and mixed carbonate-siliciclastic successions from various geological settings. This book will be of interest to sedimentary petrologists aiming to understand the distribution of diagenesis in siliciclastic and carbonate successions, to sequence stratigraphers who can use diagenetic features to recognize and verify interpreted key stratigraphic surfaces, and to petroleum geologists who wish to develop more realistic conceptual models for the spatial and temporal distribution of reservoir quality. This book is part of the International Association of Sedimentologists (IAS) Special Publications. The Special Publications from the IAS are a set of thematic volumes edited by specialists on subjects of central interest to sedimentologists. Papers are reviewed and printed to the same high standards as those published in the journal Sedimentology and several of these volumes have become standard works of reference.

Description : Sequence stratigraphic principals can be applied to carbonate rock sequences. Typical tropical shallow-water carbonate shelves lead to sequence boundary exposure across carbonate platforms, and carbonate deep water deposits during highstands. Rapid carbonate sedimentation across a shelf leads to vertical accretion during the TST and progradation during the HST. Reef-bound shelf margins tend to evolve into escarpment margins with megabreccia development on the slope. Examples are the Devonian of the Canning Basin and the Cretaceous of Mexico. Carbonate ramps typically develop lowstand prograding complexes. Cool-water carbonates develop ramp morphology, independent of light with no framework reefs, and parallel the sequence stratigraphic framework of siliciclastics. The cool water sediments of the Great Australian Bight is an example Mud mound sequences as seen in Morocco are generally independent of sea-level changes, so most sequence stratigraphic concepts are not applicable. In mixed carbonate-siliciclastic situations reciprocal sedimentation results with HST carbonates dominating in the basin and LST clastics dominating in the basin. Sequence stratigraphic concepts are generally not applicable to lacustrine carbonates, but lake dessication cycles present a similar stratigraphic framework as seen in the Tertiary Green River of the Western United States.

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.

Description : Earth's Evolving Systems: The History of Planet Earth is intended as an introductory text that examines the evolution of the Earth and its life from a systems point of view. The text covers major topics like the lithosphere, hydrosphere, atmosphere, and biosphere, and discusses how these systems interacted with each other and evolved through geologic time. The author takes care to integrate the current state of our Earth systems with those of the past in an effort to develop students' interests in Earth system in general. It begins by examining the basics of Earth systems, including discussions of sedimentation, evolution, stratigraphy, and plate tectonics. Part Two looks at the beginning of time with the origin of the Earth and discusses its early evolution, through the origin of life and its evolution to multiculluraity. The third section goes on to cover the Paleozoic through the Neogene eras, discussing topics such as tectonics, mountain building, sea level, climate, life, and mass extinctions in each era. The final part moves on to the modern world, discussing the interactions between humans and Earth systems, with an emphasis on the climatic system. Key Features of Earth's Evolving System: - Presents the Earth as a continuously evolving and dynamic planet whose history consists of a succession of vastly different worlds very much unlike our modern Earth. - Discusses the scientific method in Chapter 1, emphasizing how historical geology differs from the standard "scientific method" presented as the paradigm of experimental sciences and of all science. - Bridges traditional historical geology texts by discussing historical information in the context of the interaction and integration of Earth systems through geologic time by using the tectonic (Wilson) cycle as a unifying theme. - Concentrates on North America but offers a global perspective on Earth systems on processes such as orogenesis, seaways, and ocean circulation, the evolution of life, and mass extinction. - Discusses rapid climate change and anthropogenic impacts in the context of a continuously evolving Earth whose environments are now being altered by anthropogenic climate change. - End-of-chapter materials include: general review questions, more challenging "Food for Thought" questions, key terms listing, and a "Sources and Further Readings" section. - Boxes throughout the text highlight interesting bits of related information, unusual occurrences, or elaborates on material presented in the text

Description : Sequence stratigraphy has advanced considerably since the early applications of the concepts on seismic data. It attempts to discern the migration of facies re sulting from changes in a combination of factors such as, sea level, tectonics, climate and sediment flux, and integrates it with a meaningful chronostratigraphy. The stratigraphic record is envisioned as a framework of repetitive packages of genetically-related strata, formed in response to the shifting base level, in which the locus of deposition of various sediment types may be anticipated. This attribute is rapidly promoting sequence stratigraphy as an indispensable tool for prediction of facies in exploration and production geology. In hydrocarbon exploration the application of sequence stratigraphy has ranged from anticipating reservoir- and source-rock distribution to predicting carbonate diagenesis, porosity and permeability. The capability to anticipate vertical and lateral distribution of facies and reservoir sands in the basinal, shoreface, incised valley-fill and regressive settings alone has been a great asset for exploration. In frontier areas, where data are often limited to seismic lines, sequence-stratigraphic methodology has helped determine the timing and of types of unconformities and anticipate transgressive- and regressive-prone intervals. In production it is aiding in field development by providing improved source and seal predictions for secondary oil recovery. A recognition of stratigraphic causes of poor recovery through improved understanding of internal stratal architecture can lead to new well recompletions and enhanced exploitation in existing fields. The sequence-stratigraphic discipline is in a state of rapid expansion.

Description : Carbonate platforms are increasingly being studied using sequence stratigraphic concepts and models borrowed from the study of siliciclastic shelves in passive margin settings. The direct transposition of the stratigraphic model for a siliciclastic shelf to its carbonate counterpart, the carbonate shelf, assumes that the two systems respond in a very similar way to changes of relative sea-level, the interpreted major control upon depositional stacking patterns. Current models depicting the sequence stratigraphic evolution of carbonate shelves are and have been frequently applied without regard for the differences between the siliciclastic and carbonate shelf depositional systems. It is the purpose of this study to test the current sequence stratigraphic model and its assumptions for a carbonate shelf. Carbonate shelves do differ quite fundamentally from their siliciclastic equivalents. The carbonate shelf has the capacity to respond in quite different ways to changes in relative sea-level, compared to siliciclastic systems, as a result of the strong physio-chemical control upon carbonate sedimentation and the potential high rates of carbonate production at the shelf margin in comparison to rates of relative sea-level rise. Carbonate sedimentation rates are also differential across a shelf and highly sensitive to slight environmental' changes such as nutrient upwelling and temperature increases or decreases. This can lead to abrupt changes of sedimentation rate not necessarily related to changes of relative sea-level. Because of these differences carbonate shelves can develop stratal patterns similar to siliciclastic settings, but in the majority of cases they are very different. In direct contrast to siliciclastic systems the lowstand systems tract is normally impoverished on the flanks of carbonate shelves. Two different end-members of lowstand sedimentation are distinguished for carbonate shelves and these reflect the inherited morphology of the slope: low angle, mud-dominated slopes are characterized by basin-floor slides and debrites during times of falling relative sea-level and by a relatively large volume autochthonous slope wedge. In direct contrast, high angle slopes are characterized by basin-floor megabreccias and volumetrically very small or even absent autochthonous slope wedges. The carbonate transgressive systems tract can also develop a wide variety of stratal patterns, a reflection of the often complex interplay of variable sedimentation rates and rates of relative sea-level rise. Two different types of geometric stacking pattern are distinguished: type 1 geometries, developed when sedimentation rates are less than rates of relative sea-level rise, and type 2 geometries formed when sedimentation rates are equal to or greater than rates of relative sea-level rise. The highstand systems tract is the time of maximum carbonate production potential and is normally associated with rapid basinwards progradation. For the highstand systems tract two different types of foreslope progradation are distinguished, slope aprons and toe-of-slope aprons. These differences between carbonate and siliciclastic depositional models suggest that simple application of the previously published models can lead to incorrect interpretation of systems tracts, sequences and therefore relative sea-level curves. Sequence stratigraphic models and concepts are tested by application to the spectacular seismic scale exposures of the mid-Cretaceous Urgonian platform, SE France. The platform is divided into a lower regressive' part, the Glandasse Formation and an upper 'transgressive' part the Urgonian Limestone Formation. These are dominated by progradational outer-shelf grainstone facies and aggradational shelf-lagoonal facies respectively. Criteria are developed to identify key surfaces and stratal packages upon the Urgonian platform. On the shelf sequence boundaries are readily defined and are marked by sub-aerial exposure surfaces associated with meteoric diagenesis. Lowstand sedimentation is generally absent, but can be represented by lacustrine facies. Strong erosional truncation is only developed on the shelf if siliciclastics are introduced during lowstand of sea-level. Thus, the transgressive and highstand systems tracts dominate shelf sedimentation but can only be distinguished if a clear flooding surface is developed, and this is not always the case. On the slope large-scale erosional surfaces developed by sedimentary bypass and/or slope collapse can develop at any stage of a sequence and make identification of the sequence boundary more difficult Similarly, on the basin-floor allochthonous debris derived from slope collapse and/or bypassing is not restricted to times of falling relative sea-level. From the criteria developed for identification of key stral surfaces and packages a sequence stratigraphy for the Urgonian platform is built This is placed within the time scale of Haq et al. (1987), and relative sea-level curves for the platform are constructed. These are compared to the eustatic sea-level charts from which they differ significantly. Minimum aggradation rates are also compared to other well known ancient carbonate platforms, from which the Urgonian is shown to have very high sedimentation rates.

Description : In recent years there has been a virtual explosion of stratigraphic studies utilizing the principles of sequence stratigraphy. Although the concept of time stratigraphy is not new, the packaging of depositional units into systems tracts and sequences is. This new approach has led to the reassessment of areas that in some cases have been the subject of intense geological scrutiny for decades. The fundamental principles upon which sequence stratigraphy is based are applicable at a broad range of temporal and physical scales. This volume arises from several sessions on sequence stratigraphy held at the Thirteenth International Sedimentological Congress, with emphasis on facies associations within a sequence stratigraphic framework.

Description : The following series of papers addresses the need for a sequence stratigraphic model specifically designed for cratonic mixed carbonate-siliciclastic successions. Case studies are provided primarily from the mixed carbonate-siliciclastic strata of the Lexington Limestone of Kentucky. These studies explore the sub-regional and regional distribution of decameter-scale couplets composed of clean skeletal grainstone and argillaceous limestones interbedded with shales. Analysis of six couplets that make up the Lexington Limestone along a basin profile reveals that both parts of decameter-scale couplets are widely traceable, though each undergoes a gradual lateral facies change. Subsequent investigation reveals that these six couplets are regionally traceable along strike, showing particularly good similarity to age equivalent strata in New York. More detailed studies are also provided that focus on different aspects of the couplets to help reinforce their sequence stratigraphic significance. The uppermost skeletal grainstone unit of the Lexington Limestone and basal portion of the overlying Kope Formation are analyzed in great detail, incorporating stratigraphic correlation of individual beds between closely spaced exposures, sedimentology of condensed beds and discontinuity surfaces, and faunal and taphonomic gradient analysis of limestones within this interval. The data generated suggest that this grainstone-rich succession represents a deepening-upward succession formed during sea level rise, though with slightly varying degrees of influx of argillaceous sediments (lowstand, early transgression, and late transgression, respectively). Additional case-studies focus on the contact at the base of the grainstone-dominated half of the couplet. This contact, contrary to previous studies, is almost always sharp and erosional. In fact, detailed analysis reveals two closely spaced erosion surfaces, one at the contact of the two halves of the couplet (forced regression surface), typically overlain by argillaceous calcarenite (falling stage systems tract), and one slightly higher (sequence boundary) overlain by more massive grainstones (lowstand, etc.). Combination of the case-study data with the literature of discontinuity surfaces and condensed beds allows for the formation of a general sequence stratigraphic framework for foreland basins. Finally, a unified model for foreland basin sequence stratigraphy is presented by integrating knowledge of the carbonate margin of middle Paleozoic foreland basins with well-established models concerned with the siliciclastic margin.
