Book Description
Migmatites are highly heterogeneous rocks found in high-grade metamorphic environments; they are commonly encountered in the continental crust. Until now, many geologists have been deterred from working with migmatites because of their complex appearance and an unhelpful non-genetic nomenclature. In his Atlas of Migmatites, Dr. Edward Sawyer provides genetically based definitions and a system of nomenclature with which it will be possible to describe and map migmatites effectively and to understand how combinations of factors and processes produce a bewildering morphological diversity. Migmatites are produced by partial melting; to aid the reader in the identification of migmatites, the author describes and illustrates microstructures that can be used to infer the presence of melt or a melt-producing reaction. He also describes how geochemical data can be used to infer petrological processes involved in migmatite development. This book includes the results from two decades of research in whole-rock geochemistry, partial melting, microstructural analysis and experimental deformation of partially molten rocks. It contains information from an outcrop through to a grain scale. Exceptionally well illustrated, with 272 colour plates and accompanying detailed captions, the Atlas provides descriptions and analyses of migmatites not previously available.

Book Description
With its small population and low GDP, Mongolia is frequently deemed "unique" or tacked onto various area studies programs: Inner Asia, Central Asia, Northeast Asia, or Eurasia. This volume is a response to the concern that countries such as Mongolia are marginalized when academia and international diplomacy reconfigure area studies borders in the postsocialist era. Would marginalized countries such as Mongolia benefit from a reconfiguration of area studies programs or even from another way of thinking about grouping nations? This book uses Mongolia as a case study to critique the area studies methodology and test the efficacy of another grouping methodology, the "-scapes" method proposed by Arjun Appadurai. Could the application of this approach for tracing individuals' social networks by theme (finance, ethnicity, ideology, media, and technology) be applied to nation-states or peoples? Could it then prevent Mongolia from slipping through the cracks of academia and international diplomacy? Experts from ecology, genetics, archaeology, history, anthropology, and international diplomacy contemplate these issues in their chapters on Mongolia through the ages. Their work includes over 30 maps to help situate Mongolia in its geologic, geographic, economic, and cultural matrix. By comparing maps of different time periods and intellectual orientations, readers can consider for themselves the place of Mongolia in the world community and the relative benefits of these and other grouping methodologies.

Book Description
Discovery of Oyu Tolgoi: A Case Study of Mineral and Geological Exploration provides a detailed account of the exploration for copper deposits that took place in Mongolia in the mid-1990s, an exploration that was first started by Magma Copper and then continued by BHP Billiton World Exploration Inc., and which subsequently lead to the discovery of Oyu Tolgoi, a major metal mine. This book commemorates the 20-year anniversary for the global mining industry, including details on exploration methods, the tools applied throughout the discovery, and how the applied models evolved over the course of the execution of the exploration program. In addition, the book presents how the knowledge of the team evolved as they further understood the regional geology and the necessary geological conditions for a significant porphyry discovery. - Includes a detailed description of the anthology of the Oyu Tolgoi mine discovery, a major copper-gold porphyry deposit - Offers practical lessons for exploration companies through coverage of the critical factors that lead to the success of the discovery, along with the institutional factors that hindered discovery - Features nearly 70 never-before-seen full-color illustrations and photos of Oyu Tolgoi

Book Description
This volume provides a state-of-the-art account of the geology of part of Central Asia named The Central Asian Orogenic Belt (CAOB). This Belt formed by accretion of island arcs, ophiolites, oceanic islands, seamounts, accretionary wedges, oceanic plateaux and microcontinents (c. 1000-250 Ma ago) by similar processes to those in the circum- Pacific Mesozoic-Cenozoic accretionary orogens. Also known as Altaids, this region is one of the largest orogenic belts on Earth, extending from the Ural Mountains in the West to far eastern Siberia. It is the product of a complex evolution lasting for more than 800 million years from the latest Mesoproterozoic to the end of the Palaeozoic. The CAOB consists of numerous accreted terranes, made up of island arcs, oceanic plateaux and islands, Precambrian microcontinents and remnants of oceanic crust that are preserved as fragmented ophiolites. Although the broad history if this huge territory is now reasonably well understood there are still major unanswered questions such as the rate and volume of crustal growth, the origin of continental fragments, the detailed mechanism of accretion and collision, the role of terrane rotations during the orogeny, and the age and composition of the lower crust in Central Asia. Large parts of Central Asia (Kazakhstan, Kyrgyzstan, Siberia and parts of Mongolia) treated in this volume have only been poorly covered in scholarly western publications. Most contributions of this book are by Russian scientists actively involved in field and laboratory research of the CAOB and therefore have an intimate knowledge of the terranes which they describe and analyze. In view of the increasing significance of Central Asia because of its wealth of mineral resources this volume is of interest to readers from all fields of the geosciences and from academics to industry.

Book Description
“A tour de force…highlights the odd reptiles that roamed all corners of the earth millions of years ago.”—Sydney Morning Herald From the outback of Australia to the Gobi Desert of Mongolia and the savanna of Madagascar, the award-winning science writer and dinosaur enthusiast John Pickrell embarks on a world tour of new finds, meeting the fossil hunters who work at the frontier of discovery. He reveals the dwarf dinosaurs unearthed by an eccentric Transylvanian baron; an aquatic, crocodile-snouted carnivore bigger than T. rex that once lurked in North African waterways; a Chinese dinosaur with wings like a bat; and a Patagonian sauropod so enormous it weighed more than two commercial jet airliners. Other surprising discoveries hail from Alaska, Siberia, Canada, Burma, and South Africa. Why did dinosaurs grow so huge? How did they spread across the world? Did they all have feathers? What do sauropods have in common with 1950s vacuum cleaners? The stuff of adventure movies and scientific revolutions, Weird Dinosaurs examines the latest breakthroughs and new technologies that are radically transforming our understanding of the distant past. “This history of the discovery of some of the most outlandish creatures that ever lived, and the excitement of paleontological research, will be sure to both entertain and instruct.”—Spencer Lucas, author of Dinosaurs: The Textbook, Sixth Edition “Fascinating.... Readers learn of beautiful opalised dinosaur bones from Australia and a crested dinosaur found approximately 13,000 feet up Antarctica's Mt. Kirkpatrick, demonstrating that dinosaurs were widely distributed across the globe.”—Publishers Weekly
