Download or read book Structural Control of Mineral Deposits written by Alain Chauvet and published by MDPI. This book was released on 2019-04-16 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Structural Control” remains a crucial point that frequently lacks in any scientific and/or economic analysis of ore deposits, whatever their type and class. The case of lode deposits is exemplary, although also other deposits, like breccia pipe, stockwerk, massive sulphides, skarn, etc., can, surprisingly, be concerned. Several concepts like the gold-bearing shear zone have not proven valid during the last few decades in terms of our understanding of gold deposit and have been totally abandoned. Additionally, the relationships between magmatism, regional tectonic context, and mineralization remain uncertain and have been debated in several recent publications. This demonstrates that this issue is still relevant, and its solution may help in the distinction between intrusion-related and orogenic deposits. In this Special Issue, we particularly invite any case study of mineral deposits, in which it has been demonstrated that structural geology may have a significant role in the establishment of the deposit model of formation and/or on exploration and exploitation programs. Examples in which the structural model diverges from those described in the classical literature are particularly welcomed, including studies in which relationships with magmatism can be suspected and/or demonstrated. Indeed, all cases that illustrate concepts that differ from the classic ones and from theoretical models may represent significant contributions to this volume.
Download or read book Atlas of Shear Zone Structures in Meso scale written by Soumyajit Mukherjee and published by Springer Science & Business Media. This book was released on 2013-10-30 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Study of structures associated with shear zones is a crucial aspect to understand the deformation mechanism associated with such zones. Shear zones have been emphasized since it will lead to many latest applied studies such as radioactive waste disposal, groundwater flow etc. For the sake of brevity, research papers cannot show all possible variation in structures found in shear zones. The proposed book aims to present some of these structures in great details with attractive colour photographs. Each photograph will have a comprehensive caption.

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.

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 African Mining 91 written by Institution of Mining and Metallurgy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second 'African Mining' conference is planned for June 1991, and follows the first, very successful, event held in May 1987. That full four-year period was characterized by substantial changes in the political and economic climate of many countries in both hemispheres. Copper prices were relatively firm, and the advance and steady demand for nickel and ferrochromium stabilized important sectors of the mineral industry, certainly in Zimbabwe. The promise for gold remained unfulfilled, but the smaller, relatively flexible, mines survived and only the large, deep and low-value mines seem seriously at risk. None of this has affected the hungry, and intensive exploitations from surface to the water-table have revealed many targets of promise to those willing to take the risks. The pattern in Southern Africa was extraordinarily stable among the turmoil, with independence for Namibia, adjustments in South Africa and a gradual shift to market economies in the region. The pace of exploration has increased to recover some part of the progress that was lost in the Independence struggle, and atthe end of the first decade in Zimbabwe, for example, oil is being sought in the Zambesi Rift, following the investigation of the Luangwa in Zambia, and there are exciting exploration projects for methane released from coal, deep in its basins.
Download or read book The Geology of Egypt written by Zakaria Hamimi and published by Springer Nature. This book was released on 2019-09-19 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: This richly illustrated book offers a concise overview of the geology of Egypt in the context of the geology of the Arab Region and Northeast Africa. An introductory chapter on history of geological research in Egypt sheds much light on the stages before and after the establishment of Egyptian Geological Survey (the second oldest geological survey worldwide), Hume's book and Said's 1962, 1990 books. The book starts with the Precambrian geology of Egypt, in terms of lithostratigraphy and classifications, structural and tectonic framework, crustal evolution and metamorphic belts. A dedicated chapter discusses the Paleozoic-Mesozoic-Cenozoic tectonics and structural evolution of Egypt. A chapter highlights the Red Sea tectonics and the Gulf of Suez and Gulf of Aqaba Rifts. Subsequent chapters address the Phanerozoic geology from Paleozoic to Quaternary. The Egyptian Impact Crater(s) and Meteorites are dealt with in a separate chapter. The Earth resources in Egypt, including metallic and non-metallic ore deposits, hydrocarbon and water resources, are given much more attention throughout four chapters. The last chapter addresses the seismicity, seismotectonics and neotectonics of Egypt.
