Ultrahigh Pressure Metamorphism (UHPM) is a fast growing discipline that was established 25 years ago after discoveries of high pressure minerals, coesite and diamonds. The current explosion of research on UHMP terranes reflects their significance for understanding large scale mantle dynamics, major elements of plate tectonics such as continental collisions, deep subduction and exhumation, mountains building, geochemical recycling 'from surface to the core', and a deep storage of light elements participating in green-house effects in the atmosphere. This book provides insights into the formation of diamond and coesite at very high pressures and explores new ideas regarding the tectonic setting of this style of metamorphism. Important, authoritative and comprehensive one-stop resource for the growing ultrahigh pressure metamorphism UHPM research community A forward-looking approach founded upon a detailed historical perspective on UHPM presents the trends in discovery, methodology and theory over the last 25 years, allowing readers to gain a clear understanding of the current trends and the approaches that will shape the science in the future A highly diverse set of articles, covering a wide range of methods and sub-disciplines

This 10-chapter volume encompasses contributions from a wide spectrum of Earth science disciplines, including geophysics, geodynamics, geochemistry, and petrology, to provide an overview of the nature and evolution of the crust-mantle and lithosphere-asthenosphere boundaries in different tectonic settings, combining studies that exploit different types of data and interpretative approaches. The integration of geochemical, geophysical, and geodynamic data sets and their interpretation provides a state-of-the-art summary of current understanding, and will serve as a blueprint for future research activities.

The Treatise on Geochemistry is the first work providing a comprehensive, integrated summary of the present state of geochemistry. It deals with all the major subjects in the field, ranging from the chemistry of the solar system to environmental geochemistry. The Treatise on Geochemistry has drawn on the expertise of outstanding scientists throughout the world, creating the reference work in geochemistry for the next decade. Each volume consists of fifteen to twenty-five chapters written by recognized authorities in their fields, and chosen by the Volume Editors in consultation with the Executive Editors. Particular emphasis has been placed on integrating the subject matter of the individual chapters and volumes. Elsevier also offers the Treatise on Geochemistry in electronic format via the online platform ScienceDirect, the most comprehensive database of academic research on the Internet today, enhanced by a suite of sophisticated linking, searching and retrieval tools.

International Kimberlite Conferences (IKCs) are special events that are held across the world once in four to five years. IKC is the confluence platform for academicians, scientists and industrial personnel concerned with diamond exploration and exploitation, petrology, geochemistry, geochronology, geophysics and origin of the primary diamond host rocks and their entrained xenoliths and xenocrysts (including diamond) to get together and deliberate on new advances in research made in the intervening years. Ever since the organization of first IKC in 1973 and its tremendous success, the entire geological world eagerly look forward to subsequent such conferences with great enthusiasm and excitement. The scientific emanations from IKCs continue to make significant impact on our understanding of the composition, nature and evolution of the planet we live on. The previous conferences were held at Cape Town (1973), Santa Fe, New Mexico (1977), Clermont-Ferrand, France, (1982), Perth, Western Australia (1987), Araxa, Brazil (1991), Novosibirsk, Russia (1995), Cape Town (1998), Victoria, Canada (2003) and Frankfurt, Germany (2008). The 10th IKC was held at Bangalore, India between 5th and 11th February 2012. The conference was organized by the Geological Society of India in association with the government organizations, academic institutions and Indian diamond mining companies. About 300 delegates from 36 countries attended the conference and 224 papers were presented. The papers include 78 oral presentations and 146 poster presentations on following topics: Kimberlite geology, origin, evolution and emplacement of kimberlites and related rocks, petrology and geochemistry of metasomatised lithospheric mantle magmas, diamond exploration, cratonic roots, diamonds, diamond mining and sustainable developments and policies and governance of diamond exploration. Pre- and post-conference field trips were organized to (i) the diamond bearing kimberlites of Dharwar Craton in South India, (ii) lamproites of Bundelkhand Craton in northern India and (iii) diamond cutting and polishing industry of Surat, Gujarat in western India. A series of social and cultural programmes depicting cultural diversity of India were organized during the conference. The Kimberlite fraternity enjoyed yet another socially and scientifically successful conference.

The 30th International Geological Congress was held in Beijing, China in August 1997. Leading scientists convened to present their findings and views to the international geological research community. Volume 14 of 26 focuses on structural geology and geomechanics. All articles in the proceedings have been refereed and keynote papers have been included in Volume 1. These proceedings aim to present a view of contemporary geology and should be of interest to researchers in the geological sciences.

Der Entschluß, ein Buch über den Ursprung (bzw. die Ursprünge) des - bens zu verfassen, setzt voraus, daß man von diesem wissenschaftlichen „großen Problem“ noch immer fasziniert ist, wenn auch die erste intensive Beschäftigung mit dieser Thematik mehr als drei Jahrzehnte zurückliegt. Experimentelle Arbeiten über Protein-Modellsubstanzen unter den si- lierten Bedingungen der Urerde führten zur Entstehung eines der ersten deutschsprachigen Bücher über „Chemische und Molekulare Evolution“, das ich mit Klaus Dose (Mainz), von dem auch die Initiative ausging, v- faßte. Die enorme Erweiterung und Differenzierung dieses Forschungsgebietes führte in den letzten Jahren zur Gründung eines neuen, interdisziplinären Wissenschaftszweiges, der „Exo-/Astrobiologie“. Sie verfolgt das we- gespannte, ehrgeizige Ziel, das Phänomen „Leben“ im gesamten Kosmos zu erforschen. In den folgenden Kapiteln wird ein Überblick über die vielfältigen - mühungen von Wissenschaftlern gegeben, Antworten auf die Frage nach dem „Woher“ des Lebens zu finden. Dabei ist über Erfolge, aber auch Mißerfolge sowie über Diskussionen und gelegentlich harte Kontroversen zu berichten. Es soll aber auch deutlich dargestellt werden, wie viele of- ne Fragen und ungeklärte Rätsel noch auf eine Antwort warten. Es sind - ren mehr, als gern eingestanden wird! – Die Fülle an wissenschaftlichen Publikationen macht es leider unmöglich, über alle Bereiche dieses int- disziplinär ausgerichteten Teilgebietes der Naturwissenschaften mit gl- cher Ausführlichkeit zu berichten.
