In controlling continental break-up, extensional tectonics is one of the most fundamental processes that shape the face of our planet. Extension and break-up is key to understanding the evolution of continents, and the origin of sedimentary basins and their hydrocarbon potential, as well as the thermo-haline circulation in the oceans and, thus, global climate.
The Island of Syros (Cyclades, Greece) is a prime locality for the study of processes active in deep levels of orogens and is world famous for its exceptionally well preserved blueschist- to eclogite-facies lithologies. Syros Island was completely remapped at a scale of 1:25,000. Detailed lithostratigraphical observations and area-wide, closely spaced structural measurements allowed a much more detailed depiction of the highly variable lithological assemblage, as well as of the complex structural evolution. Lithostratigraphical indications, such as the distribution of Mn-mineralization and sequential repetition of characteristic marker successions, suggest that the whole-rock pile of the Cyc...

"The Franciscan subduction complex formed a long-lived accretionary wedge of Late Jurassic through Oligocene age that fringed the western edge of the North American Cordillera. This volume summarizes absolute finite-strain data from the Franciscan subduction complex and brittle strain data from important faults in and above this complex. Because the Franciscan is generally considered a prototypical sediment-rich subduction complex, its tectonic evolution is important for understanding convergent plate margins, and the results outlined in this volume may have broad implications for other subduction-zone settings."--pub. desc.
The geology of the Oman Mountains, including the Jabal Akhdar and Saih Hatat domes, is extraordinarily well-exposed and diverse, spanning a geological record of more than 800 Ma. The area is blessed with first-class outcrops and is well known in the geological community for its ophiolite. The Oman Mountains have much more to offer; including, Neoproterozoic diamictites (‘Snowball Earth’), fossil-rich Permo–Mesozoic carbonates and metamorphic rocks. The arid climate and deep incision of wadis allow for nearly complete rock exposure which can be investigated in all three dimensions. The diverse geology is also responsible for the breathtaking landscape. New roads and the nature of the friendly Omani people make fieldwork unforgettable. This Memoir provides a thorough state-of-the-art overview of the geology and tectonics of the Southeastern Oman Mountains, and is accompanied by an oversized geological map.
In this field-trip guide we explore the tectonics of Samos and the Menderes Massif, two fascinating areas within the eastern Mediterranean section of the Tethyan orogen. We include detailed outcrop descriptions, maps, and diagrams to explore along-strike variations in the Hellenide-Anatolide orogen, including the architecture of the Early Tertiary Alpine nappe stack and its strong Miocene extensional overprint. The suggested itinerary is based on the 2010 Geological Society of America Field Forum "Significance of Along-Strike Variations for the 3-D Architecture of Orogens: The Hellenides and Anatolides in the Eastern Mediterranean." We start the outcrop descriptions with Day 1 in Samos, wher...
From his stunning discovery of Tyrannosaurus rex one hundred years ago to the dozens of other important new dinosaur species he found, Barnum Brown led a remarkable life (1873–1963), spending most of it searching for fossils—and sometimes oil—in every corner of the globe. One of the most famous scientists in the world during the middle of the twentieth century, Brown—who lived fast, dressed to the nines, gambled, drank, smoked, and was known as a ladies’ man—became as legendary as the dinosaurs he uncovered. Barnum Brown brushes off the loose sediment to reveal the man behind the legend. Drawing on Brown’s field correspondence and unpublished notes, and on the writings of his daughter and his two wives, it discloses for the first time details about his life and travels—from his youth on the western frontier to his spying for the U.S. government under cover of his expeditions. This absorbing biography also takes full measure of Brown’s extensive scientific accomplishments, making it the definitive account of the life and times of a singular man and a superlative fossil hunter.
High number of high-quality line drawings and photographs not only support the text but also give readers vaulable experience in interprating what they observe in the field. Newest developments in microtectonics have been included in all chapters so that al chapters have been revised and updated, e.g. new information on brittle microstructures
The discoveries of the last decade have brought about a completely revised understanding of human evolution due to the recent advances in genetics, palaeontology, ecology, archaeology, geography, and climate science. Written by two leading authorities in the fields of physical anthropology and molecular evolution, Processes in Human Evolution presents a reconsidered overview of hominid evolution, synthesising data and approaches from a range of inter-disciplinary fields. The authors pay particular attention to population migrations - since these are crucial in understanding the origin and dispersion of the different genera and species in each continent - and to the emergence of the lithic cultures and their impact on the evolution of cognitive capacities. Processes in Human Evolution is intended as a primary textbook for university courses on human evolution, and may also be used as supplementary reading in advanced undergraduate and graduate courses. It is also suitable for a more general audience seeking a readable but up-to-date and inclusive treatment of human origins and evolution.
