Book Description
Sequence stratigraphy has become a powerful tool in the basin analysis of the North Sea Basin, and will continue to play an important role in the maximization of the remaining hydrocarbon potential of the region, whilst also supporting the energy transition in carbon capture and storage projects with Jurassic storage units. This Memoir provides a long-awaited, comprehensive documentation of Jurassic to lowermost Cretaceous sequence stratigraphy of the region (UK, Norway, Denmark and adjacent areas). The volume is amply illustrated by numerous well log displays, core images, seismic lines, chronostratigraphic diagrams and outcrop photographs. Individual chapters discuss the historical usage of sequence stratigraphy in the North Sea Jurassic, sequence stratigraphic concepts and models, application in hydrocarbon field development, definition of stratigraphic traps, well sequence interpretation methodology and controls on sequence development. To complete the volume there are further chapters on North Sea Jurassic lithostratigraphy and its relation to sequence stratigraphy, and descriptions of the biozones used to characterize and correlate the sequences.

Book Description
The Southern Permian Basin, as its name suggests, is a historical heartland for hydrocarbon production from the Palaeozoic Rotliegend interval. However, in this mature basin the Mesozoic presents further possibilities to offer resource security to NW Europe. Such opportunities include increasing efficiency in the production of discovered hydrocarbons, exploration for further hydrocarbons (both conventional and unconventional) and efficient exploration for, and production of, geothermal energy. All these potential resources require a grounding in technically sound geoscience, via traditional scientific observation and the application of new technologies, to unlock their value. The main aim of this volume is to bring together the work of academics and industry workers to consider cross-border geoscience including contributions on Poland, Germany, The Netherlands, the United Kingdom and adjacent areas. The work presented intends to contribute to the development and discovery of further Mesozoic energy resources across the basin.

Book Description
Volume 2 provides an overview of the Mesozoic and Cenozoic evolution of Central Europe. This period commenced with the destruction of Pangaea and ended with the formation of the Alps and Carpathians and the subsequent Ice Ages. Separate summary chapters on the Permian to Cretaceous tectonics and the Alpine evolution are also included. The final chapter provides an overview of the fossils fuels, ore and industrial minerals in the region.

Book Description
Eocene elastic sediments of the central and northern North Sea comprise five stratigraphic sequences. Oldest is the sand-dominated, basin-centered Frigg sequence, which includes submarine fan and apron deposits on the Beryl Terrace and in the Central and Viking Grabens. Middle Eocene Lower and Upper Hordaland sequences are mixed mud and sand units which prograded from the East Shetland Platform and Moray Firth and include discrete slope aprons and basin-center fans. The thin, regressive sand-prone Belton sequence marks the top of the Eocene in most of the basin, except on the eastern margin of the Shetland Platform, where the foreshelf pro grading prism of Thet sequence sandstones and siltstones was deposited. Foraminiferal biofacies analysis of a well on the Beryl Terrace indicates that four or the five sequence boundaries coincide with significant changes in the benthic and planktic foraminiferal assemblages. Cluster analysis confirms the distinct biofacies characterizing each sequence, an impoverished coarsely agglutinated fauna with radiolaria in the Frigg sequence, normal abundances or coarsely agglutinated forms in the Hordaland units, and "Velasco"-type deep-water calcareous benthics in the Upper Eocene, including planktic foraminifera in the Belton. Paleoenvironmental analysis or these biofacies shows an overall Eocene shallowing from lower slope to outer shelf. Subsidence analysis using the derived water depths indicates that the Eocene was part or a major phase of subsidence which began in the Late Paleocene and abated by Oligocene time. Overall, the Eocene constitutes a tectonosequence, or stratigraphic sequence attributable to tectonic influences. Eocene circum-North Sea tectonics include Atlantic domain seafloor-spreading to the north and west and the encroaching Alpine compression from the south. The base Eocene, top Frigg, and top Eocene all correlate with changes in seafloor spreading thought to have contributed, through intraplate stresses, to the stress regime and differential topography of the source area and basin. Latest Eocene eustatic lowering, climatic cooling, and Arctic water circulation are thought to have influenced the Thet sequence.

Book Description
This study focuses on the main depocenter of the Andrew Formation in the Moray Firth Basin, located at the junction of the Central and Viking Grabens, in the central North Sea. The objectives of this report are to (1) define the sequence stratigraphic framework of the Andrew Formation, (2) describe and characterize the depositional systems associated to the Andrew slope to basin system, and (3) interpret the depositional processes that have dominated sediment emplacement. Specific facies association of the Andrew Formation are determined by the nature (point source or linear source) and caliber (volume, grain size, sand:mud) of sediment supply to the slope environment. Genetic interpretation of the Andrew Formation focuses on understanding depositional processes which dominated sediment emplacement. Seven depositional facies have been identified for the Andrew slope and basinal system; turbidite channel-fills, turbidite lobes, mounded turbidite lobes, sheet turbidites, debris flows and slumps, low density turbidites and hemipelagic drapes. Seven depositional processes collectively create the above mentioned Andrew depositional facies; turbidity currents, cohesive mud flows, sandy debris flows, muddy debris flows, slumping, low density turbidity currents and suspension settling. The Andrew Formation consists of upper and lower depositional units identified on seismic by bounding downlap terminations and on well logs by high-gamma marker beds. The lower Andrew displays three distinct sand-rich lobes, delineated by isopach and sand percent maps and log motif characteristics. Proximal, mounded, sand-rich units disperse into unchannelized sheet turbidites in the basin plain areas. The upper Andrew downlaps the lower unit, and a single, linear sediment source was centered in the Witch Ground Graben. The sediment dispersal pattern and internal facies character suggest the upper unit is a proximal slope-apron downlapping and filling inter-lobe bathymetric lows of the underlying unit. The lower Andrew is interpreted to be a structurally focused, sand-rich lobe complex, without associated incised canyons. The Andrew system evolved as the delta platform expanded onto the proximal fan, resulting in a linear sediment source spilling over the slope as a fringing slope-apron. The Andrew depositional system in the slope and basin environment is characterized by a high degree of facies disorganization composed of a wide array of gravity-flow deposits.
