35 Seasons of U.S. Antarctic Meteorites (1976-2010)


Book Description

The US Antarctic meteorite collection exists due to a cooperative program involving the National Science Foundation (NSF), the National Aeronautics and Space Administration (NASA), and the Smithsonian Institution. Since 1976, meteorites have been collected by a NSF-funded field team, shipped for curation, characterization, distribution, and storage at NASA, and classified and stored for long term at the Smithsonian. It is the largest collection in the world with many significant samples including lunar, martian, many interesting chondrites and achondrites, and even several unusual one-of-a-kind meteorites from as yet unidentified parent bodies. Many Antarctic meteorites have helped to define new meteorite groups. No previous formal publication has covered the entire collection, and an overall summary of its impact and significant samples has been lacking. In addition, available statistics for the collection are out of date and need to be updated for the use of the community. 35 seasons of U.S. Antarctic Meteorites (1976-2011): A Pictorial Guide to the Collection is the first comprehensive volume that portrays the most updated key significant meteoritic samples from Antarctica. 35 seasons of U.S. Antarctic Meteorites presents a broad overview of the program and collection nearly four decades after its beginnings. The collection has been a consistent and reliable source of astromaterials for a large, diverse, and active scientific community. Volume highlights include: Overview of the history, field practices, curation approaches Special focus on specific meteorite types and the impact of the collection on understanding these groups (primitive chondrites, differentiated meteorites, lunar and martian meteorites) Role of Antarctic meteorites in influencing the determination of space and terrestrial exposure ages for meteorites Statistical summary of the collection by year, region, meteorite type, as well as a comparison to modern falls and hot desert finds The central portion of the book features 80 color plates each of which highlights more influential and interesting samples from the collection. 35 seasons of U.S. Antarctic Meteorites would be of special interest to a multidisciplinary audience in meteoritics, including advanced graduate students and geoscientists specializing in mineralogy, petrology, geochemistry, astronomy, near-earth object science, astrophysics, and astrobiology.




The Transantarctic Mountains


Book Description

This book presents a summary of the geology of the Transantarctic Mountains for Earth scientists who may want to work there or who need an overview of the geologic history of this region. In addition, the properties of the East Antarctic ice sheet and of the meteorites that accumulate on its surface are treated in separate chapters. The presentation ends with the Cenozoic glaciation of the Transantarctic Mountains including the limnology and geochemical evolution of the saline lakes in the ice-free valleys. • The subject matter in this book is presented in chronological order starting about 750 million years ago and continuing to the present time. • The chapters can be read selectively because the introduction to each chapter identifies the context that gives relevance to the subject matter to be discussed. • The text is richly illustrated with 330 original line drawings as well as with 182 color maps and photographs. • The book contains indexes of both subject matter and of authors’ names that allow it to be used as an encyclopedia of the Transantarctic Mountains and of the East Antarctic ice sheet. • Most of the chapters are supplemented by Appendices containing data tables, additional explanations of certain phenomena (e.g., the formation and seasonal destruction of stratospheric ozone), and illustrative calculations (e.g., 38Cl dates of meteorites). • The authors have spent a combined total of fourteen field seasons between 1964 and 1995 doing geological research in the Transantarctic Mountains with logistical support by the US Antarctic Program. • Although Antarctica is remote and inaccessible, tens of thousands of scientists of many nationalities and their assistants have worked there and even larger numbers of investigators will work there in the future.

Accretion of Extraterrestrial Matter Throughout Earth’s History


Book Description

Every year Earth is bombarded with about 40,000 tons of extraterrestrial material. This includes microscopic cosmic dust particles shed by comets and asteroids in outer space, meteorites, as well as large comets and asteroids that have led to catastrophic events in the geologic past. Originally considered only a curiosity, extraterrestrial matter found on Earth provides the only samples we have from comets, asteroids and other planets. Only recently mankind has started to actively collect extraterrestrial matter in space (Apollo program, Stardust mission) rather than to wait for its delivery to Earth. Still, most of our knowledge of the origin and evolution of our solar system is based on careful studies of meteorites, cosmic dust, and traces of large impact events in the geologic record such as the mass extinction that terminated the Cretaceous Period and led to the extinction of the dinosaurs. This book summarizes our current knowledge of the properties, origin, orbital evolution and accretion mechanism of extraterrestrial matter accreted on Earth and sheds light on accretion processes and fluxes in the geologic past. The chapters in the first part of the book are arranged in order to follow extraterrestrial matter from its origin in space, its orbital evolution on its way to Earth, its interaction with the Earth magnetosphere and atmosphere to its more or less violent collision with the Earth's surface. In the second part of the book several chapters deal with the present?day flux of cosmic dust and meteorites to Earth. Finally, several chapters deal with the reconstruction of the accretion history of extraterrestrial matter on Earth, starting with the most recent geologic past and ending with the very early, violent accretion period shortly after the formation of Earth, Moon and other solid planets in our solar system.
