Book Synopsis Characterizing the Relative Timing and Conditions of Gold and Base-metal Deposition in the Northern Part of the Yellowknife Greenstone Belt, Northwest Territories, Canada by : Amanda D. Smith
Download or read book Characterizing the Relative Timing and Conditions of Gold and Base-metal Deposition in the Northern Part of the Yellowknife Greenstone Belt, Northwest Territories, Canada written by Amanda D. Smith and published by . This book was released on 2011 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complexity of gold-mineralization styles is recognized in the north end of the Yellowknife Greenstone Belt (YGB), ~30 km north of Yellowknife. These include volcanogenic massive sulfides, sulfide zones at intersections of shear zones, and quartz veins crosscutting metavolcanic and intrusive rocks. Gold-mineralized areas are hosted in the Kam Group and Banting Group metavolcanic and metasedimentary rocks, which are older and younger, respectively, than rocks that host major ore bodies in Yellowknife. Ore petrology of each group shows early arsenopyrite-pyrite-gold deposition followed by later base-metal sulfide overprinting. Mineralization in the Banting Group is dominated by abundant pyrrhotite, a feature not observed in the Kam Group. This may indicate that chemically unique ore-depositing systems operated within the Kam and Banting Groups. Fluid inclusion, cathodoluminescence and stable isotope studies allow documentation of the nature of multiple fluids that affected these rocks. Data are interpreted to indicate that distinct styles of gold mineralization in the Kam and Banting Groups formed from their own individual hydrothermal systems.

Available in PDF, EPUB and Kindle. Book excerpt: This paper begins by describing a multidisciplinary, integrated geoscientific survey of surficial materials, ice flow history, and soil geochemistry in the Yellowknife area. It then describes the regional setting & surficial sediments in the Yellowknife Greenstone Belt, which extends north from Yellowknife. Finally, it presents findings of drift prospecting investigations related to ice flow indicators, provenance of pebbles found in drift, and numbers of gold grains in till.
Book Synopsis Uranium-lead Ages of Defeat Granitoid Rocks Near the Con Mine, Yellowknife, Northwest Territories by :
Download or read book Uranium-lead Ages of Defeat Granitoid Rocks Near the Con Mine, Yellowknife, Northwest Territories written by and published by . This book was released on 2002 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was undertaken in an attempt to provide absolute age constraints on gold mineralization in the gold mines of the late Archean Yellowknife greenstone belt. It was necessary to use indirect approaches to bracket the age of mineralization, since suitable rock types for uranium-lead geochronology are rare within the gold-bearing systems themselves. The approach involves investigating relationships between regional deformation structures and granitic dikes & small plutons in order to provide a meaningful maximum age for the second of two regional deformation events. That event either post- dates or is synchronous with mineralization. The paper reports the ages of two pre-deformation granitoid rocks of the Defeat plutonic suite from near the Con gold mine.

Book Synopsis Structural and Metamorphic Evolution of the Ormsby Zone and Relative Timing of Gold Mineralization: a Newly Defined Archean Orogenic Gold Prospect Hosted on the Discovery Property, Yellowknife Greenstone Belt, Slave Province, Canada by :
Download or read book Structural and Metamorphic Evolution of the Ormsby Zone and Relative Timing of Gold Mineralization: a Newly Defined Archean Orogenic Gold Prospect Hosted on the Discovery Property, Yellowknife Greenstone Belt, Slave Province, Canada written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Yellowknife greenstone belt has produced approximately 14 million ounces of gold, 13 of which came from the well explored southern half of the belt. The northern half of the belt, where the Discovery Property (1 million ounce past producer) is located, is not as well explored, but geologically very similar to the gold producing southern half. Gold on the Discovery Property, Northwest Territories, has been historically mined from a quartz vein formed adjacent to Archean metabasaltic bodies enclosed in metasedimentary rocks. Some of the metasedimentary rocks are correlated to the Archean Banting Group, based on a U-Pb age of 2.66 Ga on zircon (SHRIMP-RG). The metabasalt is correlated to the Banting Group based on its deposition relationship with the adjacent metasedimentary rocks. The Banting Group is present in the Yellowknife greenstone belt, located near the well-known Con and Giant Mines near Yellowknife, 90 km to the south. The two gold deposits forming the Discovery Property contains almost 2 million ounces in past production and current resources. The historical Discovery Mine was developed in quartz veins hosted in the metasedimentary rocks folded around the northern tip of one of the metabasalt bodies. In contrast, the newly defined Ormsby Zone consists of gold in silicified and sulphidized domains within metamorphosed pillowed and brecciated mafic volcanic rocks, and shares many characteristics with other Archean Orogenic gold deposits. Pyrrhotite " arsenopyrite is directly correlated with the gold-bearing zones. Gold is also associated with pyrite and retrograde phases of chlorite, sericite and carbonate. Through detailed outcrop mapping and petrography the history of structural and metamorphic events are sequenced and the relative time of gold mineralization placed into the geological framework. Peak-metamorphic mineral assemblages on the property record upper greenschist to amphibolite facies conditions. Rocks on the Discovery Property have undergone.

Book Synopsis The Metabolism of Arsenite by : Joanne M. Santini
Download or read book The Metabolism of Arsenite written by Joanne M. Santini and published by CRC Press. This book was released on 2018-10-03 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up to 200 million people in 70 countries are at risk from drinking water contaminated with arsenic, which is a major cause of chronic debilitating illnesses and fatal cancers. Until recently little was known about the mobility of arsenic, and how redox transformations determined its movement into or out of water supplies. Although human activities contribute to the release of arsenic from minerals, it is now clear that bacteria are responsible for most of the redox transformation of arsenic in the environment. Bacterial oxidation of arsenite (to the less mobile arsenate) has been known since 1918, but it was not until 2000 that a bacterium was shown to gain energy from this process. Since then a wide range of arsenite-oxidizing bacteria have been isolated, including aerobes and anaerobes; heterotrophs and autotrophs; thermophiles, mesophiles and psychrophiles. This book reviews recent advances in the study of such bacteria. After a section on background—geology and health issues—the main body of the book concerns the cellular machinery of arsenite oxidation. It concludes by examining possible applications. Topics treated are: The geology and cycling of arsenic Arsenic and disease Arsenite oxidation: physiology, enzymes, genes, and gene regulation. Community genomics and functioning, and the evolution of arsenite oxidation Microbial arsenite oxidation in bioremediation Biosensors for arsenic in drinking water and industrial effluents
