Available in PDF, EPUB and Kindle. Book excerpt: The carbonate-hosted ore deposits at Leadville, Gilman, Red Cliff, Aspen, Alma, Tincup, Kokomo, and Mount Sherman have enjoyed a long and storied production history. These orebodies, as well as dozens of smaller deposits, are all located in the central Colorado mineral belt and together constitute an important metallogenic province.

Download or read book Of Rock and Rivers written by Ellen E. Wohl and published by Univ of California Press. This book was released on 2009-06-08 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This beautifully written and deeply personal collection of essays paints a progressive view of the American West as seen by a geologist. Ellen Wohl traces her twenty years of living and conducting research in the natural landscapes of the West as she investigates the conflict between environmental history and widely held romanticized views of the region. Wohl grew up in Ohio, subscribing to a common perception of the American West as an unchanged frontier. Moving to Arizona, she became enthralled with how the landscapes and ecosystems of the West have undergone change, both through geologic time and during the historical era of European settlement. These essays tell of her early training as a geomorphologist and provide a memorable account of her research in the rivers of the West. As the lessons accrue, Wohl gives us the benefit of her experience and shows how years of studying and living in the Colorado Rockies have enhanced her understanding of landscape change through time. Building on the literary tradition of Joseph Wood Krutch, Terry Tempest Williams, and John McPhee, Wohl provides an up-to-date portrait of the West and brings a new urgency to the call for conservation of the region's land, water, and resources.

Download or read book Studies of Cave Sediments written by Ira D. Sasowsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: John E. Mylroie and Ira D. Sasowsky' Caves occupy incongruous positions in both our culture and our science. The oldest records of modem human culture are the vivid cave paintings from southern France and northern Spain, which are in some cases more than 30,000 years old (Chauvet, et ai, 1996). Yet, to call someone a "caveman" is to declare them primitive and ignorant. Caves, being cryptic and mysterious, occupied important roles in many cultures. For example, Greece, a country with abundant karst, had the oracle at Delphi and Hades the god of death working from caves. People are both drawn to and mortified by caves. Written records ofcave exploration exist from as early as 852 BC (Shaw, 1992). In the decade of the 1920's, which was rich in news events, the second biggest story (as measured by column inches of newsprint) was the entrapment of Floyd Collins in Sand Cave, Kentucky, USA. This was surpassed only by Lindbergh's flight across the Atlantic (Murray and Brucker, 1979).

Download or read book Metal Deposits in Relation to Plate Tectonics written by Frederick J. Sawkins and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book metal deposits, in particular those of non-ferrous and precious metals, are classified and analyzed in terms of their plate tectonic settings. This approach allows a meaningful treatment of metal deposits of different types and provides significant insights into both their genesis and formative environments. The updated 2nd edition incorporates the most significant advances in economic geology of the last 5 years. Particular attention is paid to the geological settings and generative models of gold deposits of all kinds.
