The West African margin has enjoyed a rich and varied exploration history, remaining an exciting region for hydrocarbon discovery. Fusion of traditional approaches, imaginative ideas, leveraged with modern technologies is still yielding success. This volume examines the margin from regional to pore-scale, from surface-processes to deep crustal levels, drawing on input from academia and industry.
The Azores archipelago in the Atlantic Ocean is composed of nine volcanic islands and São Miguel is the largest and most volcanically active. During the past 5000 years several eruptions have taken place on the three active central volcanoes – Sete Cidades, Fogo and Furnas – and in the basaltic fissure systems of Picos and Congro. There is evidence that Furnas was in eruption when the first settlers arrived some time between 1439 and 1443. In the sixteenth and seventeenth centuries there were two explosive sub-Plinian eruptions, Fogo in 1563 and Furnas in 1630. The last eruption on land occurred in the Picos Fissural Volcanic System in 1652, involving the extrusion of lava domes. In 22 chapters, this volume considers the volcanic geology of the island under the headings of geological setting, volcanic history, geological hazards and risk assessment, volcano monitoring and natural resources.
In the current cost-constrained environment for hydrocarbon exploitation, increasing emphasis is being placed on robust subsurface description and a clear understanding of the range of uncertainty associated with reservoir models. Structural heterogeneity, particularly at the subseismic scale, forms an integral part of these refined descriptions as it allows greater prediction of subsurface flow characteristics. This volume examines the best current practice and new challenges in hydrocarbon reservoir characterization and modelling of small to subseismic deformation features through case studies, experimental results and modelling. The papers follow four themes: characterization of deformati...
Pterosaurs, the first vertebrates to evolve powered flight, are undergoing a long-running scientific renaissance that has seen sustained, and even elevated interest, from several generations of palaeontologists. These incredible reptiles are known from every continent, flew the Mesozoic skies for at least 160 million years, diversified into more than a dozen major clades and well over 100 species, and included the largest flying animals of all time. This volume brings together leading pterosaur researchers from around the globe to discuss new and cutting-edge research into various aspects of pterosaur palaeobiology and presents diverse papers to deliver new insights on flying reptile palaeoecology, flight, ontogeny, skeletal and soft-tissue anatomy, temporal and spatial distribution and evolution, as well as revisions of their taxonomy and interrelationships.
Geotourism, as a form of sustainable geoheritage tourism, was defined and developed, from the early 1990s, to contextualize modern approaches to geoconservation and physical landscape management. However, its roots lie in the late seventeenth century and the emergence of the Grand Tour and its domestic equivalents in the eighteenth century. Its participants and numerous later travellers and tourists, including geologists and artists, purposefully explored wild landscapes as‘geotourists’. The written and visual records of their observations underpin the majority of papers within this volume; these papers explore some significant geo-historical themes, organizations, individuals and locations across three centuries, opening with seventeenth century elite travellers and closing with modern landscape tourists. Other papers examine the resources available to those geotourists and explore the geotourism paradigm. The volume will be of particular interest to Earth scientists, historians of science, tourism specialists and general readers with an interest in landscape history.
Geological techniques are widely used in two aspects of serious criminal investigations: (1) the search for clandestine burial sites, based on near-surface geophysics or through the detection of decomposition signals and (2) the analysis of trace evidence to identify its source location or test the possible association between the trace evidence and a known location of an offence. Although geoforensics is used in such investigations world-wide there are still considerable gaps in the published literature. In addition, there is increasing concern regarding the illegal release of wastes either into the atmosphere, water courses or on to the land surface, and a growing realization that the techniques used in criminal forensics are equally useful in the investigation of environmental crime. This book bridges the gap between environmental and criminal geoforensics with conceptual, methodological and case study contributions. This demonstrates the significant potential that geoforensics holds for investigating and regulatory officers.
The discipline of Integrated Environmental Modelling (IEM) has developed in order to solve complex environmental problems, for example understanding the impacts of climate change on the physical environment. IEM provides methods to fuse or link models together, this in turn requires facilities to make models discoverable and also to make the outputs of modelling easily visualized. The vision and challenges for IEM going forward are summarized by leading proponents. Several case studies describe the application of model fusion to a range of real-world problems including integrating groundwater and recharge models within the UK Environment Agency, and the development of ‘catastrophe’ models to predict better the impact of natural hazards. Communicating modelling results to end users who are often not specialist modellers is also an emerging area of research addressed within the volume. Also included are papers that highlight current developments of the technology platforms underpinning model fusion.
The Aeolian Islands form one of the most active geological structures in the Mediterranean area, comprising a number of active (Stromboli and Vulcano) and dormant (Panarea and Lipari) volcanoes. They have attracted the attention of scientists in modern and historical times and are the cradle of the scientific discipline of volcanology. This Memoir provides information on geological features of the Aeolian Islands volcanoes at a regional scale and for each island. The stratigraphy, structural evolution, eruptive and magmatic history of the Islands is presented, along with the geodynamic setting of the Aeolian volcanism and implications for magma origin and evolution processes. Particular focus is given to the active and dormant volcanoes and the related natural hazards. It includes a DVD with new 1:10,000-scale geological maps of the Aeolian Islands and bathymetric maps of sectors of the Aeolian archipelago, together with an extended dataset of rock compositions.
Palaeomagnetism is a technique used to understand complex deformation patterns in fold-and-thrust belts; it can be used to characterize the distribution, magnitude and timing of vertical axis rotations, an elusive variable using other methods. A combination of palaeomagnetic and structural geology analyses has helped to unravel the geometry and kinematics of fold-and-thrust belts around the world and of different geological ages for more than 50 years. This volume comprises three sections: the first shows thorough overviews of western Mediterranean arcs and the western Carpathians; the second depicts several examples from the Andes, the Alps, Anatolia, Pyrenees, Iberian Ranges and the Atlas; and the third shows the latest research on the use of palaeomagnetism to understand fold-and-thrust belts in 3D and 4D in a more quantitative way and it also includes some methodological proposals to avoid common errors. In the papers of the first two sections, the combination of palaeomagnetic analyses with structural data, AMS or magnetostratigraphic analyses demonstrate the usefulness of palaeomagnetism in deciphering complex deformation patterns in fold-and-thrust belts.
Anatolia and the easternmost Mediterranean region, especially Turkey, Cyprus and northern Syria, represent an excellent natural laboratory for the study of fundamental geological processes (e.g. rifting, seafloor spreading, ophiolite genesis and emplacement, subduction, exhumation and collision). Their interaction has created an intriguing array of deep-sea basins, microcontinents and suture zones.The volume's 22 papers include a large amount of new field-based information (much of it multidisciplinary and the product of teamwork). After an overview, the volume is divided into four sections: Late Palaeozoic--Early Cenozoic of the Pontides (northern Turkey); Late Palaeozoic--Early Cenozoic of the Taurides--Anatolides (central and southern Turkey); Late Cretaceous--Pliocene sedimentary basins and structural development (central Anatolia to the Mediterranean); Late Miocene--Recent Neotectonics (southern Turkey, Cyprus and northern Syria). The volume will interest numerous academic researchers, those concerned with resources (e.g. hydrocarbons; mineral deposits) and also hazards (e.g. earthquakes), as well as advanced undergraduate and postgraduate students -- P. 4 of cover.
