Bitumens in Ore Deposits


Book Description

This volume covers the occurrence, interpretation and significance of bitumens (hydrocarbon residues) in ore deposits. Bitumens occur with a wide variety of ores, including deposits of base metals, mercury, uranium, gold and other precious metals. The papers included reflect this variety of bitumen occurrences and the potential for obtaining useful data from them. The contributions are written by acknowledged experts in this field, who cover analytical techniques and case studies using diverse petrographic and geochemical approaches which will give ore geologists and geochemists an excellent insight into the interpretation of bitumens during mineral exploration. The large number of plates in particular will help the non-specialist to make good use of the volume through the application to new deposits. This is the most comprehensive set of contributions published on a subject of growing interest; at a time when explorationists are increasingly recognising the occurrence of bitumens in ore deposits and the fact that the evolution of mineralising fluids and hydrocarbon fluids may be closely interlinked.




Noble and Precious Metals


Book Description

The use of copper, silver, gold and platinum in jewelry as a measure of wealth is well known. This book contains 19 chapters written by international authors on other uses and applications of noble and precious metals (copper, silver, gold, platinum, palladium, iridium, osmium, rhodium, ruthenium, and rhenium). The topics covered include surface-enhanced Raman scattering, quantum dots, synthesis and properties of nanostructures, and its applications in the diverse fields such as high-tech engineering, nanotechnology, catalysis, and biomedical applications. The basis for these applications is their high-free electron concentrations combined with high-temperature stability and corrosion resistance and methods developed for synthesizing nanostructures. Recent developments in all these areas with up-to-date references are emphasized.

One Nation Under Gold: How One Precious Metal Has Dominated the American Imagination for Four Centuries


Book Description

One Nation Under Gold examines the countervailing forces that have long since divided America—whether gold should be a repository of hope, or a damaging delusion that has long since derailed the rational investor. Worshipped by Tea Party politicians but loathed by sane economists, gold has historically influenced American monetary policy and has exerted an often outsized influence on the national psyche for centuries. Now, acclaimed business writer James Ledbetter explores the tumultuous history and larger-than-life personalities—from George Washington to Richard Nixon—behind America’s volatile relationship to this hallowed metal and investigates what this enduring obsession reveals about the American identity. Exhaustively researched and expertly woven, One Nation Under Gold begins with the nation’s founding in the 1770s, when the new republic erupted with bitter debates over the implementation of paper currency in lieu of metal coins. Concerned that the colonies’ thirteen separate currencies would only lead to confusion and chaos, some Founding Fathers believed that a national currency would not only unify the fledgling nation but provide a perfect solution for a country that was believed to be lacking in natural silver and gold resources. Animating the "Wild West" economy of the nineteenth century with searing insights, Ledbetter brings to vivid life the actions of Whig president Andrew Jackson, one of gold’s most passionate advocates, whose vehement protest against a standardized national currency would precipitate the nation’s first feverish gold rush. Even after the establishment of a national paper currency, the virulent political divisions continued, reaching unprecedented heights at the Democratic National Convention in 1896, when presidential aspirant William Jennings Bryan delivered the legendary "Cross of Gold" speech that electrified an entire convention floor, stoking the fears of his agrarian supporters. While Bryan never amassed a wide-enough constituency to propel his cause into the White House, America’s stubborn attachment to gold persisted, wreaking so much havoc that FDR, in order to help rescue the moribund Depression economy, ordered a ban on private ownership of gold in 1933. In fact, so entrenched was the belief that gold should uphold the almighty dollar, it was not until 1973 that Richard Nixon ordered that the dollar be delinked from any relation to gold—completely overhauling international economic policy and cementing the dollar’s global significance. More intriguing is the fact that America’s exuberant fascination with gold has continued long after Nixon’s historic decree, as in the profusion of late-night television ads that appeal to goldbug speculators that proliferate even into the present. One Nation Under Gold reveals as much about American economic history as it does about the sectional divisions that continue to cleave our nation, ultimately becoming a unique history about economic irrationality and its influence on the American psyche.
