Isotopic Studies in Cretaceous Research by A.-V. Bojar,M. C. Melinte-Dobrinescu,J. Smit Pdf
Isotopic studies combined with geochemical, lithological, mineralogical and palaeontological investigations have been widely used in reconstructing Cretaceous marine and continental environments. Furthermore stable and radiogenic isotope trends play an important role in the interpretation of the causes and consequences of biotic turnovers at stratigraphic boundaries as well as in global correlations.

Anthony Fiorillo has been exploring the Arctic since 1998. For him, like many others, the Arctic holds the romance of uncharted territory, extreme conditions, and the inevitable epic challenges that arise. For Fiorillo, however, the Arctic also holds the secrets of the history of life on Earth, and its fossils bring him back field season after field season in pursuit of improving human understanding of ancient history. His studies of the rocks and fossils of the Arctic shed light on a world that once was, and provide insight into what might be.

Stable Isotope Studies of the Water Cycle and Terrestrial Environments by A-V. Bojar,A. Pelc,C. Lécuyer Pdf
This volume is devoted to Earth surface environmental reconstructions and environmental changes that may be deciphered and modelled using stable isotopes along with mineralogical/chemical, sedimentological, palaeontological/biological and climatological methodologies. The book is divided into two sections, both using stable isotopes (see www.geolsoc.org.uk/SP507) in various samples and phases as the main research tool. The first section is devoted to studies focusing on the distribution of isotopes in precipitation, groundwater, lakes, rivers, springs, tap water, mine water and their relationship with terrestrial environments at regional to continental scale. In relation to this, the second section includes case studies from a range of continental settings, investigating cave deposits (stalagmites, bat guano), animal skeletons (dinosaurs, alligators, turtles, bivalves), present and past soils (palaeosols) and limestones. The sections focus on the interaction between the surficial water cycle and underground water storage with deposits acting as archives of short- to long-term climatic and environmental changes. Examples from the Early Cretaceous to present time come from Europe, Asia, Africa, North and South America.
Advances in South American Micropaleontology by Gabriela Catalina Cusminsky,Emiliana Bernasconi,Graciela Andrea Concheyro Pdf
This book offers many examples of calcareous microfossils and describes a new microfaunistic record in Argentina. These selected papers of the 11th Argentine Paleontological Congress include micropaleontological studies on material of different geological ages from several sites in Argentina and Colombia. The authors highlight several geological findings and explain the paleoenvironmental changes in Argentina and Colombia.

The Stratigraphic Record of Gubbio by Marco Menichetti,Rodolfo Coccioni,Alessandro Montanari Pdf
Since the beginning of the last century, the lower Jurassic to mid-Miocene pelagic succession exposed along the valleys of the Umbria and Marche Apennines of Italy represented a fertile playground for generations of earth scientists. This GSA Special Paper provides a reappraisal of the geological and integrated stratigraphic research, which was carried out by scores of earth scientists in the gorges around the medieval city of Gubbio over the past fifty years. Following review chapters about pioneering sedimentologic, biostratigraphic, and magnetostratigraphic studies of the Gubbio sections, a series of papers presents new, original data addressing different stratigraphical, paleoenvironmental, and structural geological aspects of particular Cretaceous to Paleogene intervals, including the still much-debated K-Pg Boundary Event in the worldwide famous site of the Bottaccione Gorge, where the Alvarez theory of global mass extinction caused by a catastrophic extraterrestrial impact was born in 1980.
The science of climate change is a complex subject that balances the physical record and scientific fact with politics, policy, and ethics - and is of particular importance to the geosciences. This thoughtfully crafted new text and accompanying media encourage non-science majors to practice critical thinking, analysis, and discourse about climate change themes. Taking a cross-disciplinary approach, acclaimed educator and researcher, David Kitchen, examines not only the physical science, but the social, economic, political, energy, and environmental issues surrounding climate change. His goal: to turn knowledge into action, equipping students with the knowledge and critical skills to make informed decisions, separate facts from fiction, and participate in the public debate.
Cretaceous Climate Events and Short-Term Sea-Level Changes by M. Wagreich,M.B. Hart,B. Sames,I.O. Yilmaz Pdf
Sea-level constitutes a critical planetary boundary for geological processes and human life. Sea-level fluctuations during major greenhouse phases are still enigmatic and strongly discussed in terms of changing climate systems. The geological record of the Cretaceous greenhouse period provides a deep-time view on greenhouse-phase Earthsystem processes that facilitates a much better understanding of the causes and consequences of global, geologically short-term, sea-level changes. In particualr, Cretaceous hothouse periods can serve as a laboratory to better understand a near-future greenhouse Earth. This volume presents high-resolution sea-level records from globally distributed sedimentary archives of the Cretaceous involving a large group of scientists from the International Geoscience Programme IGCP 609. Marine to non-marine sedimentary successions were analysed for revised age constraints, the correlation of global palaeoclimate shifts and sea-level changes, tested for climate-driven cyclicities, and correlated within a high-resolution stratigraphic framework of the Geological Timescale. For hothouse periods, the hypothesis of significant global groundwater-related sea-level change, i.e. aquifer-eustasy as a major process, is reviewed and substantiated.
Origin, Evolution, Environmental Impact of Oceanic LIPs by Clive R. Neal,William W. Sager,Takashi Sano,Elisabetta Erba Pdf
The origin, evolution, and environmental impact of large igneous provinces (LIPs) represents a topic of high scientific importance because the magmatism associated with these features cannot be directly related to plate tectonics, and because the eruption of flood basalts may have global environmental consequences. Oceanic LIPs are even more poorly understood due to their relative inaccessibility. This volume takes a multidisciplinary approach to understanding LIP origin, evolution, and environmental impact in ocean basins. Papers that focus on plate tectonic reconstructions, petrologic and geophysical investigations of various LIPs, and sedimentological and micropaleontological evidence of syn-LIP sediments are presented. Precious materials and data from dredging cruises and scientific ocean drilling expeditions have made this volume possible.
Isotopic Proveniencing and Mobility by T. Douglas Price Pdf
This volume provides a state-of-the-art presentation and discussion of procedures, especially what works and what doesn’t — on isotopic proveniencing, learned over the last 30 years. The volume focuses on application, not method, to emphasize to the reader the wide range of questions that can be addressed using isotopic proveniencing. Topics covered include samples, baselines, isoscapes, and place of origin. Isotopic proveniencing has become almost standard procedure in the analysis of archaeological burials as a means of distinguishing locals from foreigners. The combination of isotopic proveniencing and DNA has moved archaeological interest in migration and mobility to the fore, but there is very little synthetic work published for either technology.The field has evolved and new procedures and guidelines have emerged that have not been widely heard and this volume seeks to rectify this. The contributors have been selected from among the leaders in the field, those with active research and hands-on experience with the technology. This volume is of relevance to archaeologists.
