Sedimentation and Tectonics in Rift Basins: Red Sea - Gulf of Aden presents new case studies and synthesises the results of recent research on the sedimentological evolution of the Red Sea - Gulf of Aden rift system. This rift basin is generally regarded as the best natural geological laboratory in the world in which to study the processes of rift formation. Uplift of the rift margins in an arid climate results in extensive three-dimensional exposures of pre- and syn-rift strata and associated structures. These serve as analogues for the understanding and hydrocarbon exploration of deeper buried rift-systems on continental margins such as the North Sea and the Atlantic margins. The Red Sea - Gulf of Aden rift is also exceptional in that its stratigraphy spans all stages from pre-rift environments, syn-rift continental to marine environments through the rift to drift transition to post-rift sea-floor spreading. The work is arranged in eight sections: following a review of the sedimentology and stratigraphy of rift basins, the magmatism and structural evolution of the Red Sea - Gulf of Aden rift is reviewed. Subsequently, new case studies are presented of the early rifting environment, syn-rift sedimentation, tectonics and diagenesis, evaporites and salt tectonics. Post-rift sediments of the axial trough are then discussed along with studies of reefs, coastal zone and shelf sediments, and the tectonic geomorphology of the rift margin escarpment. This work results from extensive new research in the rift basin largely carried out under collaborative research projects by European and Middle Eastern geologists. It will be an invaluable reference work for geoscientists in the hydrocarbon, groundwater and mineral extraction industries, as well as for researchers in university departments of earth sciences, mining and physical geography.

I present a new interpretation of the tectonic evolution of Orpheus basin, a narrow Mesozoic rift basin on the passive margin of offshore eastern Canada. This work incorporates insights gained from a scaled experimental modeling study that simulates multiphase deformation on a basin with a synrift ductile unit, to show that the structural deformation observed within this basin cannot completely be attributed to salt-related buoyancy-driven processes. Seismic data show that the Orpheus and overlying Scotian basins experienced at least four stages of development: Triassic-Early Jurassic rifting, shortening during the rift/drift transition in the mid-Early Jurassic, regional uplift and erosion during the earliest Cretaceous, and a fourth event that had, at least locally on the North Step, a compressional component during the Oligocene. The presence of the synrift Argo salt profoundly affected the style of deformation during both the formation of the basin, and the subsequent tectonic events. The synrift salt decoupled the cover deformation from basement deformation. Forced folds and salt ridges developed in the cover above the salt, whereas, faulting accommodated basement extension below the salt. During subsequent tectonic events, deformation was mainly accommodated above the basement faults by: 1) reactivating preexisting extensional structures such as passive salt diapirs and salt ridges, and 2) further amplifying preexisting forced folds that formed during the rifting phase. The presence of multiple unconformities, disharmonic sets of synclines and salt-cored anticlines (which developed from preexisting extensional forced folds), vertical salt welds, and detached thrusts indicate that this basin underwent multiple episodes of shortening, uplift, and erosion after rifting ended in the Early Jurassic.

Regional Geology and Tectonics: Volume 2: Phanerozoic Rift Systems and Sedimentary Basins, Second Edition, is the second volume in a three-volume series covering Phanerozoic regional geology and tectonics. Experience in analyzing and assessing rifts - locations where the Earth’s outer shell and crust have been stretched over time by seismic activity - is critical for exploration geologists in identifying Earth’s most lucrative hydrocarbon locations in which extraction is both efficient and safe. Vast compilations of related industry data present regional seismic lines and cross sections, and summaries of analogue and theoretical models are provided as an essential backdrop to the structure and stratigraphy of various geological settings. The new edition of Regional Geology and Tectonics: Volume 2: Phanerozoic Rift Systems and Sedimentary Basins features updated summaries of analogue and theoretical models. New to this edition are chapters on deepwater foldbelts and lithospheric extension as well as new case studies on volcanic and passive margin basins. Provides a practical reference for petroleum geologists that discusses the importance of rift systems and the structural evolution of the Earth Includes analyses of active rifts in East Africa, China, Siberia, the Gulf of Suez, and the Russian Arctic that provide immediately implementable petroleum exploration applications in regions heavily targeted by oil & gas companies Presents overviews of sequence stratigraphy in rifts and structural controls on clastic and carbonate sedimentation that are critical to the exact mapping of the most lucrative hydrocarbon locations by exploration geologists

In this timely volume, geoscientists from both industry and academia present a contemporary view of salt at a global scale. The studies examine the influence of salt on synkinematic sedimentation, its role in basin evolution and tectonics, and ultimately in hydrocarbon prospectivity. Recent improvements in seismic reflection, acquisition and processing techniques have led to significant advances in the understanding of salt and sediment interactions, both along the flanks of vertical or overturned salt margins, and in subsalt plays such as offshore Brazil. The book is broadly separated into five major themes covering a variety of geographical and process-linked topics. These are: halokinetic sequence stratigraphy, salt in passive margin settings, Central European salt basins, deformation within and adjacent to salt, and salt in contractional settings and salt glaciers.

This volume describes the nature, causes, and consequences of the diverse fluid movements that produce energy and mineral resources in sedimentary basins. The contained papers point to new capabilities in basin analysis methods and models. The processes that operate in the resource-producing thermo-chemical-structural reactors we call sedimentary basins are reviewed. Efficient ways to infer the tectonic history of basins are described. Impacts on hydrocarbon maturation and migration of glacial tilting, magmatic intrusion, salt migration, and fracturing are illustrated. The conditions under which subsurface flow will channel with distance traveled are identified. Seismic methods that can image and map subsurface permeability channels are described. The surface maturation, surface charge, and chemical reaction foundations of creep subsidence are set forth. Dynamic aspects of the hydrogen resource in basins are analyzed. There is much that is new that is presented in these papers with the intent of stimulating thinking and enthusiasm for the advances that will be made in future decades.

Salt and Sediment Dynamics presents a thorough treatment of salt and sediment interactions and the implications of such interactions for sub-salt exploration. The book emphasizes and utilizes recent discoveries on many aspects of salt and sediment interactions, provides the theoretical framework for interpreting the increasing amount of available data on salt and sediments, and develops a self-consistent dynamical evolution model of salt structures and their interaction with surrounding sediments. The model developed in the text consists of an evolving salt structure that influences sediment motion with self-consistent evolution of sediments and salt shape. The resulting stress and strain in the sediments and the thermal focusing effects of the salt are evaluated. The salt and sediments in the model are consistent with observed geometries, a result of having freely adjustable, observation-controlled model parameters. In addition, the book describes case histories in a variety of geological settings, thus explaining aspects of the genesis and development of salt structures, of their impact on sedimentary structural evolution, and of the impact of sediments on salt masses. The techniques developed by the authors expand the current state of knowledge regarding the evolution and dynamics of salt structures and increase the potential for effective sub-salt hydrocarbon exploration.

Dynamical Geology of Salt and Related Structures deals with many aspects of the dynamical evolution of salt bodies in sedimentary basins. This book consists of four major sections. Section A deals with salt dynamics and the motion of salt. The impact of a mobile salt mass on the structural development of the overlying formations is considered in Section B, while the development of caprock, which is commonly found overlying salt diapirs, is emphasized in Section C. The last section deliberates the interrelationships between fluid flow, salt dissolution, and heat flow in the vicinity of a salt diapir, including the connections with maturation of source rocks, migration, and trapping of hydrocarbons in salt-related structures. This publication is valuable to professional geoscientists interested in processes involved in salt dynamics.
