Lithium-cesium-tantalum (LCT) pegmatites are important resources for rare metals. For Cs, only the LCT pegmatites with the zeolite group mineral pollucite at Bikita (Zimbabwe Craton) and Tanco (Superior Province Craton) are of commercial importance. Common characteristics of world-class LCT pegmatite deposits include their Meso- to Neoarchean age and geological setting within greenstone belt lithologies on Archean Cratons. This study presents the first coherent and comparative scientific investigation of five major LCT pegmatite systems from the Yilgarn, Pilbara and Zimbabwe Craton. For the evaluation of their Cs potential and of the genetic concepts of pollucite formation, the pegmatites from Wodgina, Londonderry, Mount Deans and Cattlin Creek were compared to the Bikita pollucite mineralization. The integration of the new data (e.g., geochronological and radiogenic isotope data) into the complex geological framework: 1) enhances our knowledge of the formation of LCT pegmatite systems, and 2) will contribute to the further exploration of additional world-class LCT pegmatite deposits, which 3) may host massive pollucite mineralisations.

• Prologue : dolphin lessons
• In the beginning : humpback whales
• Searching for giants : blue whales
• Family : orcas
• In deep water : beaked whales and false killer whales
• The desert whales : gray whales.

From the author of The Hidden Lives of Owls, an exploration of the elusive lives of whales in the Pacific Ocean, home to orcas, humpbacks, sperm, blue, and gray whales. Leigh Calvez has spent a dozen years researching, observing, and probing the lives of the giants of the deep. Here, she relates the stories of nature's most remarkable creatures, including the familial orcas in the waters of Washington State and British Columbia; the migratory humpbacks; the ancient, deep-diving blue whales, the largest animals on the planet. The lives of these whales are conveyed through the work of dedicated researchers who have spent decades tracking them along their secretive routes that extend for thousands of miles, gleaning their habits and sounds and distinguishing peculiarities. The author invites the reader onto a small research catamaran maneuvering among 100-foot long blue whales off the coast of California; or to join the task of monitoring patterns of humpback whale movements at the ocean surface: tail throw, flipper slap, fluke up, or blow. To experience whales is breathtaking. To understand their lives deepens our connection with the natural world.

• Decarbonization: Climate won't wait ; What Sweden did ; What Germany did

As climate change begins to take a serious toll on the planet--with much more damage yet to come--a solution to our warming problems is hiding in plain sight. We need to commit to de-carbonizing our economy, and do so immediately, but so far we have lacked the courage to really try. Our fears of nuclear energy have grown irrationally large, even as our fears of climate change are irrationally small. In this clear-sighted and compelling book, Joshua Goldstein and Steffan Qvist come bearing good news: a real solution, one that is fast, cheap, and provably works. Based on Sweden's success cutting their carbon emissions in half, Goldstein and Qvist argue for a policy that combines nuclear and renewable energy sources. From 1970-1990, Sweden replaced coal power plants with nuclear ones, and slowly integrated renewable energy alongside it. During that same time period, the country generated more electricity than ever and its economy grew by 50 percent. They have had no nuclear accidents, nor has any of their uranium been stolen by terrorists. Separating facts from doomsday scenarios, Goldstein and Qvist force a real and meaningful dialogue about what the best energy policy is, and the dangers of remaining on our present path. And they offer an answer that really could work--if only we'd give it a try.

Focusing on both Polar Regions, this book provides a comprehensive understanding of political processes related to the rapidly changing Arctic and Antarctic, where the environmental impacts of human activities are extremely visible. Environmental changes in the Arctic and the Antarctic are increasingly seen as barometers of the global impact of human activities, while newly arising economic opportunities in both Polar Regions prompt predictions that they will be the site of future conflicts. This book maps and analyses the different actors involved in the politics of the Polar Regions to explain why similar patterns of interpretation of such major issues have become dominant in practical, popular and formal geopolitical discourses. Disentangling the politics, the author illustrates how the ordering principles have evolved, explains recent dynamics in political processes and provides the groundwork needed to better forecast future trends. By focusing on the Americas, the only continent that borders both Polar Regions, the author shows how geographic proximity inspires interaction and cooperation among state and non-state actors in very different ways. This volume will be of interest to scholars and students of political science, political geography, international relations, global governance and cultural studies. It will have an international appeal particularly in the Americas, and other countries with growing interests in the Polar Regions.

As digital technologies have become part of everyday life, mediating tasks such as work, travel, consumption, production, and leisure, they are having increasingly profound effects on phenomena that are of immediate concern to geographers. These include: the production of space, spatiality and mobilities; the processes, practices, and forms of mapping; the contours of spatial knowledge and imaginaries; and, the formation and enactment of spatial knowledge politics Similarly, there are distinct geographies of digital media such as those of the internet, games, and social media that have become indispensable to geographic practice and scholarship across sub-disciplines, regardless of conceptual approach. This textbook presents a fully up-to-date, synoptic and critical overview of how digital devices, logics, methods, etc are transforming geography. It is divided into six inter-related sections introduction to digital geographies digital spaces digital methods digital cultures digital economies digital politics With illustrious instructors and researchers contributing to every chapter, Digital Geographies is the ideal textbook for courses concerning digital geographies, digital and new media and Internet communications, and the spatial knowledge of politics.

"The material in this Field Guide includes a review of classical Kolmogorov turbulence theory, Gaussian-beam waves in free space, and atmospheric effects on a propagating optical wave. These atmospheric effects have great importance in a variety of applications like imaging, free space optical communications, laser radar, and remote sensing. This Field Guide presents tractable mathematical models from which the practitioner can readily determine beam spreading, beam wander, spatial coherence radius (Fried's parameter), angle of arrival fluctuations, scintillation, aperture averaging effects, fade probabilities, bit error-rates, and enhanced backscatter effects, among others. There have been a number of new model developments in atmospheric propagation of a laser beam since the first edition of this Field Guide to Atmospheric Optics, many of which are included in this second edition. The subject of Atmospheric Optics is more extensive than that presented here. For example, most treatments of the subject matter concentrate heavily on the scattering and absorption by the molecular gases, particulates, and aerosols in the atmosphere. This usually also includes a detailed analysis of the wind, temperature, and pressure, particularly as a function of altitude. Another area of concentration in many treatments of the subject takes into account meteorological optics, which is a fascinating area all of its own. The subject of optical phenomena is often presented in great detail covering rainbows, halos, mirages, red sunsets, and so on"-- Provided by publisher.
