3992 ðóáAmber: Tears of the Gods
Neil Clark Once a treasure more valuable than gold, amber has had a fascinating and turbulent history, a history that shaped the economies of the Baltic States. The mysterious qualities of Amber have caused it to be collected, treasured and admired since ancient times. Over thousands of years, many interesting theories have been advanced as to amber's origin and nature but, for all its varieties, colours and forms, every piece of amber originated as tree resin, fossilised over millions of years. Amber - Tears of the Gods is an extremely enjoyable introduction to this extraordinary substance, explaining exactly what amber is and where it came from. Neil Clark delves into the myths and legends which have contributed to the folklore of amber and takes the reader on a historical journey across the trade routes of Europe. He enlightens us to amber's many intriguing uses and ends by telling us of amber's surprising significance to modern science. A beautifully illustrated and constructed survey,...

2662 ðóáGlobalization and the Race for Resources (Themes in Global Social Change)
Stephen G. Bunker Book Description Globalization and the Race for Resources explores how five nations-Portugal, the Netherlands, Britain, the United States, and Japan-achieved trade dominance by devising technologies, social and financial institutions, and markets to enhance their access to raw materials. Through ecological and economic explanation of resource extraction and production, Stephen G. Bunker and Paul S. Ciccantell reveal globalization as the result of the progressive extension of systematically integrated material processes across cumulatively greater space. Drawing from extensive historical research into how economic and environmental dynamics interacted in the extraction of different materials in the Amazon, especially in the development of the iron mine of Carajas, the authors also illustrate the profound connection between global dominance and control of natural resources.

8690 ðóáKarst Environments: Karren Formation in High Mountains
Marton Veress With a focus on karren formation in high mountains, and specifically in the European Alps, this text summarizes the scientific results of systematic observations made during field trips, as well as the interpretation, using modern analytical methods, of the data collected. Marton Veress, who has been working in different types of karren landscapes for more than fifteen years, presents the conditions and processes of high mountain karren formation as well as the properties of karren features. The book analyzes karren phenomena, their development, and their formation under different environmental conditions. Introductory chapters provide an overview of karren formations, in addition to charting the history of research into karst environments at high altitude. The author then provides details of the sampling sites and the localities he has studied, and experimental procedures undertaken. After covering the details of the age and rate of karren form development, Veress gives an in-depth...

3958 ðóáTailings: Slurry, Externality, Oil Sands, Heap Leaching, Hydrogen Cyanide, Uranium Tailings, Mining, Sedimentation, Beaconsfield Mine Collapse, Coal Slurry Impoundment
High Quality Content by WIKIPEDIA articles! Tailings (also known as slimes, tailings pile, tails, leach residue, or slickens) are the materials left over after the process of separating the valuable fraction from the worthless fraction (gangue) of an ore. The extraction of minerals from ore requires that the ore be ground into fine particles, so tailings are typically small and range from the size of a grain of sand to a few microns. Mine tailings are usually produced from the mill (grinding) in slurry form (a mixture of fine mineral particles and water).

2795 ðóáThe Accidental Collector: Art, Fossils & Friendships
Wesley Wehr Book DescriptionReaders who fell in love with The Eighth Lively Art will delight in the stories and profiles that the painter and paleontologist Wesley Wehr has collected in this follow-up to his earlier memoir. Here, Wehr's subjects--the painters, poets, and thinkers whose names constitute a pantheon of Pacific Northwest artistic and intellectual life in the 1950s and 1960s--reveal a shared distaste for theorizing about their work, which for them tended to be rather haphazardly integrated into the broader career of living by one's wits. And, more than this trait, all of them in their time shared a moment and a special place in the lens of Wehr's perception, inspiring a question that their lives answered, in different ways, by example: "How does a young person learn what it is to become an artist in the world?" The profiles collected in this volume are a mosaic of the voices, episodes, images, and locales that have remained vivid in Wehr's memory. There are the growing pains of a...

9293 ðóáTravertine
Allan Pentecost This is the first book entirely devoted to travertine, a material in use for over 4000 years. The single-author work is a valuable reference source for travertine, covering all aspects of travertine origins, formation, composition, flora and fauna, occurrence and utilisation, as well as covering allied continental carbonates such as lake marls, calcretes and beachrocks. Travertine, some forms of which are often known as a?˜tufaa??, is of particular significance as a source of environmental information (fossils and isotope geochemistry), often permitting the reconstruction of past environments. Reviews of dating techniques, classification and geomorphology are included and the author attempts to provide an unbiased but critical appraisal of current models of travertine formation. Currently, travertine is in great demand as a building and ornamental stone. It has also been exploited in unconventional ways, such as a?˜petrifying springsa?? and by way of unusual and little known artistic...

Book DescriptionWith this book of color photographs of the polished hearts of stones portrayed as natural paintings, BILL ATKINSON completes his transition from whiz kid of Silicon Valley to high priest of Silica. After helping to usher in the age of personal computing by designing the graphical user interface of the Macintosh computer, Atkinson turned his visual and technical talents to nature photography. While shooting in the Painted Desert, Atkinson became intrigued with the brilliant colors in the petrified wood littering the ground. He brought home some polished rock slabs, photographed them in natural color and without magnification, and was enthralled. The photographs looked more like paintings of forgotten dreams than either rocks or photographs. Atkinson went on to borrow and photograph thousands of art-quality stones at gem shows. From these thousands of stones, Atkinson has picked for WITHIN THE STONE those seventy-two that yielded the most striking, the most...
