Download or read book Hydrothermal Alteration and Gold Deposition in the Homestake Iron formation hosted Gold Deposit Lead South Dakota written by Rayburn Chase Hamer and published by . This book was released on 2010 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Homestake deposit located in Lead, South Dakota was one of the largest gold deposits, having produced over 40 million ounces of gold from 1876 to 2001. The deposit is hosted in the Proterozoic-aged Homestake formation which is an iron formation consisting of either iron-carbonate or iron-silicate metamorphic rocks. The unit is characterized by sideroplesite in the greenschist facies and grunerite in the lower amphibolite facies, with minor chlorite, biotite, quartz, and graphite. The ore is located in and adjacent to quartz veins, and typically consists of arsenopyrite, pyrrhotite and native gold contained in a matrix of quartz±chlorite±biotite±garnet. Although mined for over 120 years, the mechanisms behind the localization of gold are still not well known.
Download or read book Petrogenesis of Metamorphic Rocks written by Kurt Bucher and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metamorphic rocks are one of the three classes of rocks. Seen on a global scale they constitute the dominant material of the Earth. The understanding of the petrogenesis and significance of metamorphic of geological education. rocks is, therefore, a fundamental topic There are, of course, many different possible ways to lecture on this theme. This book addresses rock metamorphism from a relatively pragmatic view point. It has been written for the senior undergrad uate or graduate student who needs practical knowledge of how to interpret various groups of minerals found in metamorphic rocks. The book is also of interest for the non-specialist and non-petrolo gist professional who is interested in learning more about the geolo gical messages that metamorphic mineral assemblages are sending, as well as pressure and temperature conditions of formation. The book is organized into two parts. The first part introduces the different types of metamorphism, defines some names, terms and graphs used to describe metamorphic rocks, and discusses principal aspects of metamorphic processes. Part I introduces the causes of metamorphism on various scales in time and space, and some principles of chemical reactions in rocks that accompany metamorphism, but without treating these principles in detail, and presenting the thermodynamic basis for quantitative analysis of reactions and their equilibria in metamorphism. Part I also presents concepts of metamorphic grade or intensity of metamorphism, such as the metamorphic-facies concept.
Download or read book Hydrothermal Processes and Mineral Systems written by Franco Pirajno and published by Springer Science & Business Media. This book was released on 2008-10-14 with total page 1250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrothermal processes on Earth have played an important role in the evolution of our planet. These processes link the lithosphere, hydrosphere and biosphere in continuously evolving dynamic systems. Terrestrial hydrothermal processes have been active since water condensed to form the hydrosphere, most probably from about 4.4 Ga. The circulation of hot aqueous solution (hydrothermal systems) at, and below, the Earth’s surface is ultimately driven by magmatic heat. This book presents an in-depth review of hydrothermal proceses and systems that form beneath the oceans and in intracontinental rifts, continental margins and magmatic arcs. The interaction of hydrothermal fluids with rockwalls, the hydrophere and the biophere, together with changes in their composition through time and space, contribute to the formation of a wide range of mineral deposit types and associated wallrock alteration. On Earth, sites of hydrothermal activity support varied ecosystems based on a range of chemotrophic microorganisms both at surface and in the subsurface. This book also provides an overview of hydrothermal systems associated with meteorite impacts and explores the possibility that hydrothermal processes operate on other terrestrial planets, such as Mars, or satellites of the outer planets such as Titan and Europa. Possible analogues of extraterrestrial putative hydrothermal processes pose the intriguing question of whether primitive life, as we know it, may exist or existed in these planetary bodies. Audience: This volume will be of interest to scientists and researchers in geosciences and life sciences departments, as well as to professionals and scientists involved in mining and mineral exploration.

It also documents the key features of this spectacular deposit for a wide range of professionals in the resource geology community. This world-class gold deposit has been a spectacular geological and economic success story, as it has developed from a small historical gold mine in discontinuous quartz veins measuring only meters to a large-scale mine in deposits spreading over kilometres in extensive disseminated gold-bearing rock.
Download or read book Ore Deposits in an Evolving Earth written by G.R.T. Jenkin and published by Geological Society of London. This book was released on 2015-01-02 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ore deposits form by a variety of natural processes that concentrate elements into a volume that can be economically mined. Their type, character and abundance reflect the environment in which they formed and thus they preserve key evidence for the evolution of magmatic and tectonic processes, the state of the atmosphere and hydrosphere, and the evolution of life over geological time. This volume presents 13 papers on topical subjects in ore deposit research viewed in the context of Earth evolution. These diverse, yet interlinked, papers cover topics including: controls on the temporal and spatial distribution of ore deposits; the sources of fluid, gold and other components of orogenic gold deposits; the degree of oxygenation in the Neoproterozoic ocean; bacterial immobilization of gold in the semi-arid near-surface environment; and mineral resources for the future, including issues of resource estimation, sustainability of supply and the criticality of certain elements to society.
Download or read book An Outline of the Geology of Indonesia written by Herman Darman and published by Lereng Nusantara . This book was released on 2000 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea to produce this book originated during the "Tectonics and Sedimentation of Indonesia" seminar, the first regional meeting of the Indonesian Sedimentologists Forum (FOSI), the sedimentological commission of IAGI, in 1999. The meeting was conducted to commemorate the 50 years anniversary of the publication of van Bemmelen's book, entitled "Geology of Indonesia" (1949). This was the first book to deal indepth with Indonesian geology at that time. This work was written before the offshore exploration activities and is now out of print. Van Bem-melen's book is a classic of its type that covers onshore geology and some fields of geological en-quiry that have not been superceded by more modern work. In this volume, we have attempted to compile pre-existing publications. Additional recent insights understandings were added to give an up-to-date picture of the geology of Indonesia. It was found that much of geological data have been gathered since the first exploration activity some 150 years ago but was not utilized or even widely known by geologists recently. "An Outline of the Geology of Indonesia" is a compilation of mainly published materials using post van Bemmelen's concept and understanding. We have incorporated facts, ideas, philosophies, and prejudices of many authors; some are quoted and acknowledged; others have been absorbed and blended. These materials have been bound together to gave readers a regional view of Indonesia. Our main problems have been the selection of material and the need to strike a balance between each chapter. The book is far from perfect and ongoing efforts will be made to upgrade the contents of this book. Suggestions and input are most welcome to improve the next edition. The book is organized geographically into fourteen chapters, starting from the West and ended with Irian Jaya. Each chapter covers general geology, stratigraphy, and tectonic history. We have also endeavored to list as many references as possible in order to enable users to explore for themselves the original works.
