"The Umbria-Marche Apennines are entirely made of marine sedimentary rocks, representing a continuous record of the geotectonic evolution of an epeiric sea from the Early Triassic to the Pleistocene. The book includes reviews and original research works accomplished with the support of the Geological Observatory of Coldigioco"--
Despite their global importance, little is known about the few existing examples of impacts into marine environments and icy targets. They are among the least understood and studied parts of impact crater geology. The icy impacts are also of great importance in understanding the developments of the outer planets and their satellites such as Mars or Europa. Furthermore, the impact mechanisms, crater formation and collapse, melt production and the ejecta distribution are scarcely known for impact on targets other than the "classical" solid silicates of the continental crust. The reaction of water and ice to impacts clearly deserves a more thorough study. The understanding of impact effects and...
The sixth volume in the Institute of Classical Archaeology’s series on the rural countryside (chora) of Metaponto is a study of the Greek settlement at Sant’Angelo Vecchio. Located on a slope overlooking the Basento River, the site illustrates the extraordinary variety of settlements and uses of the territory from prehistory through the current day. Excavators brought to light a Late Archaic farmhouse, evidence of a sanctuary near a spring, and a cluster of eight burials of the mid-fifth century BC, but the most impressive remains belong to a production area with kilns. Active in the Hellenistic, Late Republican, and Early Imperial periods, these kilns illuminate important and lesser-kno...
As portals to the supernatural realm that creates and animates the universe, caves have always been held sacred by the peoples of Mesoamerica. From ancient times to the present, Mesoamericans have made pilgrimages to caves for ceremonies ranging from rituals of passage to petitions for rain and a plentiful harvest. So important were caves to the pre-Hispanic peoples that they are mentioned in Maya hieroglyphic writing and portrayed in the Central Mexican and Oaxacan pictorial codices. Many ancient settlements were located in proximity to caves. This volume gathers papers from twenty prominent Mesoamerican archaeologists, linguists, and ethnographers to present a state-of-the-art survey of ri...
A Positron Named Priscilla is a book of wonder, offering a fascinating, readable overview of cutting-edge investigations by many of today's leading young scientists. Written for anyone who loves science, this volume reports on some of the most exciting recent discoveries and advances in fields from astronomy to molecular biology. This new book is from one of the world's most prestigious scientific institutions, the National Academy of Sciences. The Academy provides an annual forum for the brightest young investigators to exchange ideas across disciplinesâ€"an exchange that was the spark for A Positron Named Priscilla. Each chapter is authored by a popular science writer who offers helpful...
The Darwin College Lectures delivered in Cambridge in 1990.
This issue of the almanac aims at filling the gap in the mega-evolutionary research. The Editors believe that the present Almanac, which brings together scientists working in different areas of the vast evolutionary field, will hopefully make a contribution to this process.The contributions to this volume are subdivided into three sections:‘Universal Evolution’, ‘Biological and Social Forms of Evolution: Connections and Comparisons’, and ‘Aspects of Social Evolution’. Subjects and issues of the contributions to all three sections have a great deal in common and significantly supplement each other.
The papers in this volume provide an exhaustive inventory and description of the most complete sedimentary sequences across the Eocene-Oligocene Boundary (EOB) from all over the world, and present a synthesis of the biotic and chemico-physical events detected at the Eocene-Oligocene transition. The content of the book represents the results achieved by Project no. 174 on ``Geological Events at the Eocene-Oligocene boundary'' of the International Geological Correlation Program, sponsored by UNESCO. The project was carried out over a five year period and has provided a wealth of new and interesting information.
