This book was released on 2017-09-05 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first overview of the Toarcian Oceanic Anoxic Event in the southern Iberian paleomargin, in the western Tethys. The study of catastrophic events that affected the ecosystems in the past is of great interest, because it offers the possibility of establishing models that can be applied to current and future environmental changes. The book provides comprehensive information on the changes in marine ecosystems in connection with a global massive extinction, the Early Toarcian, and with the deposition of black shales, global warming and a disruption of the carbon cycle. In addition, the book describes the incidence of this event in this part of the Tethys close to the connection with the Protoatlantic, the Hispanic Corridor. Special attention is paid to sedimentological and ichnological aspects, fossil content (macroscopic and microscopic), and geochemistry. It also presents the facies changes related to fragmentation of the shelf and the evolution to hemipel agic troughs and swells in this paleomargin. Lastly, it characterizes this anoxic event in under-researched outcrops from southern Spain and compares the findings with those in well-known sections from northern and central Europe. This book offers a unique resource for all researchers interested in the Toarcian Oceanic Anoxic Event, but also in oceanic anoxic events that occurred during the Mesozoic in general, because of their similarity to recent climatic changes.

This book was released on 2021-11-30 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Toarcian Oceanic Anoxic Event, also known as the Jenkyns Event, was a hyperthermal episode which occurred during the early Toarcian (c. 183 Ma; Early Jurassic) and resulted in numerous collateral effects including global warming, enhanced weathering, sea-level change, carbonate crisis, marine anoxia–dysoxia, and a second-order mass extinction. This volume presents the last advances for understanding early Toarcian environmental changes through different disciplines: biostratigraphy, micropalaeontology, palaeontology, ichnology, palaeoecology, sedimentology, integrated stratigraphy, inorganic, organic and isotopic geochemistry, and cyclostratigraphy. The study of this abrupt climate change is critical for predicting future global changes, and for understanding the complex biogeochemical interactions through time between geosphere, atmosphere, hydrosphere and biosphere.
Download or read book Conservation Palaeobiology of Marine Ecosystems written by R. Nawrot and published by Geological Society of London Special Publications. This book was released on 2023-07-03 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation palaeobiology tracks the history of ecosystems based on the fossil record to guide conservation decisions and contribute to the theoretical foundations of conservation biology. The accelerating pace of global change requires better understanding of the long-term resilience and adaptive capacities of ecosystems. Fossil assemblages in outcrops and cores, together with surface accumulations of skeletal remains, represent unique archives of past ecosystem dynamics and baseline community states prior to anthropogenic impacts. However, as biological data retrieved from fossil and death assemblages cannot be treated in isolation, conservation palaeobiology integrates palaeontological and geological tools to account for the nature of the stratigraphic record. This volume brings together studies that demonstrate how combining marine palaeoecological records with other types of geohistorical data (taphonomic, sedimentological, geochronological, geochemical) can inform biodiversity conservation and ecosystem management. The papers highlight novel approaches and challenges in applying geohistorical data to conservation problems, discuss the limitations imposed by time averaging, and offer both deep- and near-time perspectives on conservation palaeobiology of marine ecosystems.
Download or read book The Geology of Iberia A Geodynamic Approach written by Cecilio Quesada and published by Springer. This book was released on 2019-06-28 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking a new global approach, this unique book provides an updated review of the geology of Iberia and its continental margins from a geodynamic perspective. Owing to its location close to successive plate margins, Iberia has played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys s.l. and Eurasian plates over the last 600 Ma of Earth's history. The geological record starts with the amalgamation of Gondwana in the Neoproterozoic succeeded by the rifting and spreading of the Rheic ocean; its demise, which led to the amalgamation of Pangea in the late Paleozoic; the rifting and spreading of several arms of the Neotethys ocean in the Mesozoic Era and their ongoing closure, which was responsible for the Alpine orogeny. The significant advances in the last 20 years have attracted international research interest in the geology of the Iberian Peninsula. This volume presents the most comprehensive, and updated description of the Alpine cycle in Iberia. This volume focuses in the different geological events during the Alpine orogeny as well as the lithological succession . This book is of interest not only for scientists of Portugal and Spain but also for geoscientists searching for analogies for oil and gas as well as tourists visiting the main mountain ridges of Iberia such as the Pyrenees.

This book was released on 1998 with total page 818 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project was designed to build a documented chronostratigraphic and outcrop record of depositional sequences calibrated across European basins. Data on standard stages, magnetostratigraphy, and geochronology integrated with high resolution biostratigraphy calibrate the stratigraphic position of depositional sequence boundaries. Higher order eustatic sequences show a significant increase in the number identified. A good portion of the European Mesozoic and Cenozoic succession is set in the sequence stratigraphic context with a stratigraphic record of its bonding surfaces.
Download or read book Carbonate Platform Demise and Recovery at the Toarcian Oceanic Anoxic Event written by Nicholas Patrick Ettinger and published by . This book was released on 2017 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sedimentological, stratigraphic, and geochemical signature of the Toarcian Oceanic Anoxic Event (OAE) on the Bahamian-style, Adriatic Carbonate Platform of Southern Europe is examined here. New stratigraphic sections correlated to previously published data show that a healthy and diverse metazoan carbonate factory characterized the flat-topped platform prior to the onset of the OAE. Carbon isotopes of marine organic matter and bulk carbonate, as well as trace element data (V, Ni, Mo, Mn, Hg) were used to identify the stratigraphic location of the OAE on the outer platform. A negative organic carbon isotope excursion of -2.2‰ coincident with enrichments in Mo and Fe was used to correlate to time equivalent strata in both the inner platform and adjacent basin. The onset of the OAE heralded a carbonate factory collapse on the outer platform that was driven by deoxygenation, eutrophication, and possibly ocean acidification. At the same time, a shallow intrashelf basin developed, while the adjacent deep-water basin accumulated black shales. The cessation of carbonate production throughout the OAE yielded a significant drowning unconformity on the outer platform as sea-level continued to rise, while restricted, organic-rich mudstones accumulated on the inner platform under a euxinic regime. Recovery of carbonate production is characterized mainly by calcitic fauna and ooids. By the Middle Jurassic, ooids generated on the outer margin spilled into the adjacent basin forming a thick deep-water oolitic fan, and they prograded to the inner platform, reestablishing a flat-topped carbonate platform.

Book excerpt: In 2018, the International Symposium on Nanogeoscience was held in Guiyang, China. Scholars from around the globe gathered to discuss recent progress and development trends in various aspects of nanogeoscience, including nanomineralogy. Nanomineralogy, an important aspect of nanogeoscience, focuses on the composition, structure, and physical and chemical properties of nanoscale minerals and their interrelations with other Earth critical components. To give a sampling of the latest progress in nanomineralogy and related fields, we offer this Special Issue, which describes a full range of recent nanomineralogic achievements relating to everything from nanominerals and geochemistry, mineral nanostructures, and nanomineral deformation, to nanopores in oil and gas reservoirs, nanomineral deposits, and nanomineral material. Today, nanomineralogy faces a new strategic opportunity as well as a revolutionary challenge. We thus present this special nanomineralogy-focused issue of Minerals with the aim of encouraging our colleagues to familiarize themselves with current developments, trends, and directions in nanomineralogy, enabling an understanding of the potential of the field as a whole. We look forward to developing further scientific research and cooperation in nanomineralogy, hoping thereby to attract and guide young scholars to participate in this field.

Download or read book Hemingway s Brain written by Andrew Farah and published by Univ of South Carolina Press. This book was released on 2017-04-18 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: A forensic psychiatrist’s second opinion on the conditions that led to Ernest Hemingway’s suicide, “mixing biography, literature and medical analysis” (The Washington Post). Hemingway’s Brain is an innovative biography and the first forensic psychiatric examination of Nobel Prize–winning author Ernest Hemingway. After seventeen years researching Hemingway’s life and medical history, Andrew Farah, a forensic psychiatrist, has concluded that the writer’s diagnoses were incorrect. Contrary to the commonly accepted diagnoses of bipolar disorder and alcoholism, he provides a comprehensive explanation of the medical conditions that led to Hemingway’s suicide. Hemingway received state-of-the-art psychiatric treatment at one of the nation’s finest medical institutes, but according to Farah it was for the wrong illness, and his death was not the result of medical mismanagement but medical misunderstanding. Farah argues that despite popular mythology Hemingway was not manic-depressive and his alcohol abuse and characteristic narcissism were simply pieces of a much larger puzzle. Through a thorough examination of biographies, letters, memoirs of friends and family, and even Hemingway’s FBI file, combined with recent insights on the effects of trauma on the brain, Farah pieces together this compelling alternative narrative of Hemingway’s illness, one missing from the scholarship for too long. Though Hemingway’s life has been researched extensively and many biographies written, those authors relied on the original diagnoses and turned to psychoanalysis and conjecture regarding Hemingway’s mental state. Farah has sought to understand why Hemingway’s decline accelerated after two courses of electroconvulsive therapy, and in this volume explains which current options might benefit a similar patient today. Hemingway’s Brain provides a full and accurate accounting of this psychiatric diagnosis by exploring the genetic influences, traumatic brain injuries, and neurological and psychological forces that resulted in what many have described as his tortured final years. It aims to eliminate the confusion and define for all future scholarship the specifics of the mental illnesses that shaped legendary literary works and destroyed the life of a master.
