This Special Issue reprint includes one review and fifteen research articles. The review by Palyanova et al. (2023) summarized the available information on the palladian gold and proposed classifying ...the types of deposits based on the fineness, content, and set of impurities in palladian gold and minerals intergrown with it. Fifteen articles focused on the typomorphic features of native gold from gold deposits in Russia, India, Chile, Scotland, and Canada. This Special Issue aims to identify and generalize the reasons for variations in the compositions of native gold. I hope all the articles in this Special Issue will be helpful and valuable resources for anyone who is interested in native gold and gold deposits. I thank the Authors and Reviewers for their efforts and contributions. I am also grateful to the Editor-in-Chief, Editors and Assistant Editors of Minerals for their help.
In 1896, a small group of prospectors discovered a stunningly rich pocket of gold at the confluence of the Klondike and Yukon rivers, and in the following two years thousands of individuals traveled ...to the area, hoping to find wealth in a rugged and challenging setting. Ever since that time, the Klondike Gold Rush - especially as portrayed in photographs of long lines of gold seekers marching up Chilkoot Pass - has had a hold on the popular imagination.
In this first environmental history of the gold rush, Kathryn Morse describes how the miners got to the Klondike, the mining technologies they employed, and the complex networks by which they obtained food, clothing, and tools. She looks at the political and economic debates surrounding the valuation of gold and the emerging industrial economy that exploited its extraction in Alaska, and explores the ways in which a web of connections among America s transportation, supply, and marketing industries linked miners to other industrial and agricultural laborers across the country. The profound economic and cultural transformations that supported the Alaska-Yukon gold rush ultimately reverberate to modern times.
The story Morse tells is often narrated through the diaries and letters of the miners themselves. The daunting challenges of traveling, working, and surviving in the raw wilderness are illustrated not only by the miners compelling accounts but by newspaper reports and advertisements. Seattle played a key role as gateway to the Klondike. A public relations campaign lured potential miners to the West and local businesses seized the opportunity to make large profits while thousands of gold seekers streamed through Seattle.
The drama of the miners journeys north, their trials along the gold creeks, and their encounters with an extreme climate will appeal not only to scholars of the western environment and of late-19th-century industrialism, but to readers interested in reliving the vivid adventure of the West s last great gold rush.
Within the last decade, the high and continuing demand for precious and base metals, as well as critical elements, has prompted a global rush on a scale never before seen. This eventually resulted in ...the demand for considerable innovation and improvement in mineral deposit genetic modelling and ore formation regimes for the many different types of gold deposits, now recognized, and paralleled by the wide employment of exploration techniques and a rapid expansion of geological databases.
This Special Issue will show case studies of porphyry polymetal systems, orogenic gold formations, water–rock reaction, ore-forming structure evolution, mineralogy and petrology of ore deposit, ore formation regime, geochronology and geochemistry of ore deposit, ore-forming evolution, mineral exploration and cutting-edge technology in ore deposit study.
A gold‐catalyzed tandem cyclization of o‐phenylenediamines with ynones to synthesize benzobindeno1,2‐e1,4diazepine has been developed. The mechanism was explored by control experiments. The method ...provides a way to access a range of benzobindeno1,2‐e1,4diazepine derivatives in diversity‐oriented synthesis aiming at discovering structurally diverse scaffolds.
Wir berichten über die direkte Synthese neuer Azulen‐Derivate durch gold‐katalysierte Zyklisierungsreaktionen. Ein fünfgliedriger Ring als Rückgrat in den verwendeten Trien‐In‐Substraten erwies sich ...als entscheidend, um die 7‐endo‐dig‐Zyklisierung zu induzieren, die für die Azulenbildung notwendig ist. Die erhaltenen Zielmoleküle sind aufgrund ihrer potenziellen Anwendungen in verschiedenen Bereichen, wie anorganische Materialien, in der Medizin oder in der Kosmetik, von großem Interesse. UV/Vis‐Spektren und Cyclovoltammetrien wurden gemessen und darauf basierend die elektronischen Eigenschaften bestimmt. Kurze zwei‐ oder dreistufige Sequenzen zum Erhalt der verwendeten Ausgangsmaterialien machen diesen Ansatz synthetisch sehr attraktiv.
Using tax and mintage records, this book provides a district-by-district annual accounting of the gold and silver officially produced and minted in colonial Latin America, placing that output within ...the context of the emerging early-modern world economy.
