The biological effects of asteroid and comet impacts have been widely viewed as primarily destructive. The role of an impactor in the K/T boundary extinctions has had a particularly important influence on thinking concerning the role of impacts in ecological and biological changes. th During the 10 and final workshop of the ESF IMPACT program during March 2003, we sought to investigate the wider aspects of the involvement of impact events in biological processes, including the beneficial role of these events from the prebiotic through to the ecosystem level. The ESF IMPACT programme (1998-2003) was an interdisciplinary effort that is aimed at understanding impact processes and their effects on the Earth environment, including environmental, geological and biological changes. The IMPACT programme has 15 member states and the activities of the programme range from workshops to short courses on topics such as impact stratigraphy, shock metamorphism, etc. The program has also awarded mobility grants and been involved in the development of teaching aids and numerous publications, including this one.

The diversity of papers presented in this volume attest to the fact that impact cratering is very much a biological process. This volume is the tenth in a series of books resulting from the activities of the scientific programme, "Response of the Earth System to Impact Processes" (IMPACT), by the European Science Foundation. The papers were presented at an international meeting at King's College, Cambridge in 2003. These papers investigate the effects of asteroid and comet impacts on a diversity of biological and evolutionary processes including the survival of organics and microbial ecosystems to the extinction of organisms.

The Mjølnir impact structure was recognized in 1993 and included in the Earth Impact Database in 1996, based on the discoveries of unequivocal meteorite impact indicators such as shocked quartz, Ir-enrichments, possible glass remnants, fragments of nickel-rich iron oxides, in addition to the convincing complex crater shape of the structure. This book presents the geological and geophysical history of the Barents Sea region along with the discovery of the Mjølnir impact crater. We place the Mjølnir event into the geological framework of the region and present elaborative numerical models of its formation and associated tsunami generation. The book represents an update and synthesis as well as the complete compilation of the Mjølnir crater studies.

Hydrothermal processes on Earth have played an important role in the evolution of our planet. These processes link the lithosphere, hydrosphere and biosphere in continuously evolving dynamic systems. Terrestrial hydrothermal processes have been active since water condensed to form the hydrosphere, most probably from about 4.4 Ga. The circulation of hot aqueous solution (hydrothermal systems) at, and below, the Earth’s surface is ultimately driven by magmatic heat. This book presents an in-depth review of hydrothermal proceses and systems that form beneath the oceans and in intracontinental rifts, continental margins and magmatic arcs. The interaction of hydrothermal fluids with rockwalls, the hydrophere and the biophere, together with changes in their composition through time and space, contribute to the formation of a wide range of mineral deposit types and associated wallrock alteration. On Earth, sites of hydrothermal activity support varied ecosystems based on a range of chemotrophic microorganisms both at surface and in the subsurface. This book also provides an overview of hydrothermal systems associated with meteorite impacts and explores the possibility that hydrothermal processes operate on other terrestrial planets, such as Mars, or satellites of the outer planets such as Titan and Europa. Possible analogues of extraterrestrial putative hydrothermal processes pose the intriguing question of whether primitive life, as we know it, may exist or existed in these planetary bodies. Audience: This volume will be of interest to scientists and researchers in geosciences and life sciences departments, as well as to professionals and scientists involved in mining and mineral exploration.

Impact cratering is arguably the most ubiquitous geological process in the Solar System. It has played an important role in Earth’s history, shaping the geological landscape, affecting the evolution of life, and generating economic resources. However, it was only in the latter half of the 20th century that the importance of impact cratering as a geological process was recognized and only during the past couple of decades that the study of meteorite impact structures has moved into the mainstream. This book seeks to fill a critical gap in the literature by providing an overview text covering broad aspects of the impact cratering process and aimed at graduate students, professionals and researchers alike. It introduces readers to the threat and nature of impactors, the impact cratering process, the products, and the effects – both destructive and beneficial. A series of chapters on the various techniques used to study impact craters provide a foundation for anyone studying impact craters for the first time.

Continental Scientific Drilling Project of the Cretaceous Songliao Basin (SK-1) in China is the first reference to provide the results of the first part of scientific drilling project at the Songliao Basin in the Daqing oil field, the largest known oil field in China. The project has two major objectives: one is to correlate the oceanic and continental records and determine the principal drivers of climate change in order to assist in future climate change predictions and its influence on the earth's environment. The second is to further test the theory of terrestrial genesis of hydrocarbons, and to explore the formation of intra-continental sedimentary basins, as many are major hydrocarbon provinces. In addition, this project provides the scientific basis for exploration of the Daqing Oilfields, which have a yearly production of forty million tons of oil. The world is entering a new exciting era to explore in which scientific drilling will provide a quantum leap in our understanding of its deep earth and history. Continental Scientific Drilling Project of the Cretaceous Songliao Basin (SK-1) in China will play an important role in promoting scientific drilling and earth system science research. - Summarizes the geological background, seismic profile, and tectonic evolution of the Songliao Basin - Provides detailed information on drilling technology of SK-1, which successfully obtained ~2500m core with a recovery rate of ~95% - Includes detailed core information: stratigraphic charts, core photographs, and core photograph identification tables

This comprehensive atlas explains the genesis and evolution of impact known craters on Earth, presenting a wealth of radar images from the Italian COSMO-SkyMed satellites that were acquired at the same frequency, spatial resolution, operating mode, and illumination, allowing excellent comparison of different impact structures. It also discusses in detail the processes that have hidden or erased terrestrial impact craters, and clearly explains the basic principles of remote sensing and the COSMO-SkyMed system and radar instruments. Also, the optical satellite remote sensing technique used to produce the optical images is described. The main section documents each of the exposed craters officially recognized as caused by meteoritic impact, presenting a table with the COSMO-SkyMed radar image and, where available, a Sentinel optical image and a photograph taken in situ. A short accompanying text reports the location, context, geographical coordinates, and other ancillary information to support future researches.

Presenting illustrative case studies, highlighting technological applications, and explaining theoretical and foundational concepts, this book is an important reference source on the key concepts for modern technologies and optimization of new processes in physical chemistry. This volume combines up-to-date research findings and relevant theoretical frameworks on applied chemistry, materials, and chemical engineering. This new volume presents an up-to-date review of modern materials and chemistry concepts, issues, and recent advances in the field. Distinguished scientists and engineers from key institutions worldwide have contributed chapters that provide a deep analysis of their particular subjects. At the same time, each topic is framed within the context of a broader more multidisciplinary approach, demonstrating its relationship and interconnectedness to other areas. The premise of this book, therefore, is to offer both a comprehensive understanding of applied science and engineering as a whole and a thorough knowledge of individual subjects. This approach appropriately conveys the basic fundamentals, state-of-the-art technology, and applications of the involved disciplines, and further encourages scientific collaboration among researchers. This volume emphasizes the intersection of chemistry, math, physics, and the resulting applications across many disciplines of science and explores applied physical chemistry principles in specific areas, including the life chemistry, environmental sciences, geosciences, and materials sciences. The applications from these multidisciplinary fields illustrate methods that can be used to model physical processes, design new products and find solutions to challenging problems.
