Book excerpt: Isotope Geochemistry: The Origin and Formation of Manganese Rocks and Ores is a comprehensive reference on global manganese deposits, including their origins and formations. Manganese is both a significant industrial chemical, critical for steel-making, and a strategic mineral, occurring in abundance only in certain countries. Furthermore, it is used effectively in CO2 sequestration, helping to mitigate greenhouse gas emission challenges around the world. For these reasons, exploration for manganese is very active, yet access to the primary academic literature can be a challenge, especially in field operations. Isotope Geochemistry brings this material together in a single source, making it the ideal all-in-one reference that presents the supporting data, analytics, and interpretation from known manganese deposits. This book is an essential resource for researchers and scientists in multiple fields, including exploration and economic geologists, mineralogists, geochemists, and environmental scientists alike. - Features coverage of the formation, origins, and deposits of manganese rocks and ores globally, arming geoscientists with a thorough reference on the subject - Includes 170 figures and illustrations that visually capture key concepts - Includes elusive data with supporting analysis and interpretation of deposits in Russia, one of the most robust geographic locations in the world for manganese rock and ore research

This book was released on 2021-07-22 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Publication combines results obtained by interdisciplinary groups from numerous academic institutions working on Paleoproterozoic formations to decipher the origins of the main mineralization resources in the West African Craton (WAC) and their impacts on African economic development. Structural, geophysical, sedimentological, stratigraphical, geochemical, petrophysical and mineralogical analyses have been used to highlight the complexities involved in mineralization emplacement and its origin and evolution within the WAC. Fourteen articles contribute to new knowledge in mineral research. They show that the geodynamic evolution of the WAC is complex from one area to another: it involves subduction, collision and obduction during several deformation phases ranging from Birimian (2.3–2.0 Ga) to Pan-African (650–450 Ma) events. Various modelling techniques, when integrated, help in understanding the mechanisms of mineralization emplacement, some of which are still a matter of debate. The challenge for further studies is mitigation for sustainable development that can be appropriately used to minimize such damage.

Download or read book Archean Crustal Evolution written by K.C. Condie and published by Elsevier. This book was released on 1994-11-11 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of Tectonics/Geochemistry, up-to-date reviews by leading scientists as well as a broad topical coverage of the Archean, are some of the features of this particular volume. As geochronology has progressed in the last 20 years, the Archean has continued to attract interest. Advancements in the understanding of Archean crustal and mantle evolution have progressed rapidly since the first International Archean Symposium in Western Australia (1970). The landmark for the Archean was the NATO Advanced Study Institute at Leicester (1975). At this meeting the Archean truly "came of age". Investigators from many different disciplines focused their expertise on the early history of the earth. For the first time, the nature of the atmosphere, oceans, and life during the Archean was an important part of an Archean symposium. During the most recent Archean Symposium in Perth in 1990, there was a shift in interest from field and trace element data to the new rapidly evolving high-precision U/Pb geochronology of Archean rocks and to detailed structural studies of both low and high grade Archean terrains. The terrane concept so widely applied to the Phanerozoic was proposed for the Archean Yilgarn Province in Western Australia and is now widely accepted for the Archean (as evident by the articles in this book). Plate tectonics is now widely accepted as the principal process that controls the history of continents and oceans. There are, though, well substantiated differences between Archean and post-Archean rocks that indicate that Archean tectonic regimes must have differed in some respects from modern ones. The question of how and to what degree did Archean plate tectonics differ from modern plate tectonics is treated in many of the chapters of this book. Altogether, the editor has presented a selection of articles that provide a fascinating insight into the latest observations in this field.
Download or read book Explanatory Notes for the Geological Map of Southwest Ghana 1 100 000 written by Geoffrey Loh and published by . This book was released on 1999 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the results of geological mapping and research work performed in southwestern Ghana. The studied area covers about 2000 km2 and comprises the land surface south of latitude 5° N and between longitude 1°30' W and 2°30' W. It is prospective for gold and manganese and includes supracrustal and intrusive rocks of the Birimian Supergroup, subordinately sedimentary rocks of the Tarkwaian Group, as well as minor, late-kinematic basin-type granitoids - all of Paleoproterozoic age. Furthermore, Paleozoic and Cretaceous sediments are present locally. The two geological sheets at the scale of 1:100,0000 (Axim and Sekondi) and cover the southern tip of the Ashanti volcanic belt which is the prime gold producer of Ghana, the southernmost part of the Kumasi sedimentary basin and migmatitic gneisses representing a comparatively deep crustal level of the Cape Coast sedimentary basin. Most of the investigated terrane, however, is occupied by three major synvolcanic/belt-type granitoid plutons from which precise U-Pb zircon crystallization ages of 2172 + 2 Ma and 2174 + 2 Ma are available. Regional foliation trends NE-SW or NNE-SSW, being the result of Eburnean NW-SE compression of the terrane. Three major high-strain zones occur, one of which represents the southern continuation of the important gold-bearing Prestea-Obuasi-Konongo high-strain zone. 26 gold occurrences and four manganese occurrences - abandoned European as well as active and abandoned native ones - were inventarized and their characteristics and features are presented in tabular form. The two most important regional controls for gold deposition seem to be the high-strain zone in and adjacent to the belt/basin transition zone on the western flank of the Ashanti belt, in accordance with conceptions previously established by GSD and BGR, as well as sheared granitoid/greenstone contacts.

Download or read book Mineral Deposits and Earth Evolution written by Geological Society of London and published by Geological Society of London. This book was released on 2005 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mineral deposits are not only primary sources of wealth generation, but also act as windows through which to view the evolution and interrelationships of the Earth system. Deposits formed throughout the last 3.8 billion years of the Earth's history preserve key evidence with which to test fundamental questions about the evolution of the Earth. These include: the nature of early magmatic and tectonic processes, supercontinent reconstructions, the state of the atmosphere and hydrosphere with time, and the emergence and development of life. The interlinking processes that form mineral deposits have always sat at the heart of the Earth system and the potential for using deposits as tools to understand that evolving system over geological time is increasingly recognized. This volume contains research aimed both at understanding the origins of mineral deposits and at using mineral deposits as tools to explore different long-term Earth processes.
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.
