Download or read book Processes and Ore Deposits of Ultramafic Mafic Magmas through Space and Time written by Sisir K. Mondal and published by Elsevier. This book was released on 2017-09-08 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processes and Ore Deposits of Ultramafic-Mafic Magmas through Space and Time focuses on the fundamental processes that control the formation of ore deposits from ultramafic-mafic magmas, covering chromite, platinum-group element (PGE), Ni-sulfides and Ti-V-bearing magnetite. The exploration, exploitation and use of these magmatic ores are important aspects of geology and directly linked to the global economy. Magmatic ores form from ultramafic-mafic magmas and crystallize at high-temperature after emplacement into crustal magma chambers, and are genetically linked to the evolution of the parental magmas through space and time. This book features recent developments in the field of magmatic ore deposits, and is an essential resource for both industry professionals and those in academia. - Elucidates the relationships between tectonic settings and magmatic ore mineralization - Provides the links between magma generation in the mantle and ore mineralization at crustal levels - Features the latest research on changing patterns in magmatic ore mineralization through time and their bearing on the chemical evolution of the Earth's mantle

Book excerpt: This edited work contains the most recent advances related to the study of layered intrusions and cumulate rocks formation. The first part of this book presents reviews and new views of processes producing the textural, mineralogical and geochemical characteristics of layered igneous rocks. The second part summarizes progress in the study of selected layered intrusions and their ore deposits from different parts of the world including Canada, Southwest China, Greenland and South Africa. Thirty experts have contributed to this update on recent research on Layered Intrusions. This highly informative book will provide insight for researchers with an interest in geology, igneous petrology, geochemistry and mineral resources.

Download or read book Main Tectonic Events and Metallogeny of the North China Craton written by Mingguo Zhai and published by Springer. This book was released on 2016-07-25 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the metallogeny and main tectonic events of the North China Craton from early Precambrian to Phanerozoic. It covers the Archean crustal growth, Paleoproterozoic rifting-subduction-collision processes, Great Oxidation Event, Meso-Neoproterozoic multiple rifting, Phanerozoic reworking of the North China Craton, as well as metallogeny related to above different processes. The North China Craton is one of the oldest cratons in the world. It has experienced a complex geological evolution since the early Precambrian, and carries important records of secular changes in tectonics and metallogeny. It provides a systematic review and new results on the growth and evolution of the North China Craton and metallogeny. It will be of broad interest to the earth scientists working in the fields of economic geology, geochemistry, and tectonics of the North China Craton and eastern Asian.

Download or read book The Geologic Time Scale 2012 written by F M Gradstein and published by Elsevier. This book was released on 2012-08-14 with total page 1176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field. The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)

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.

Available in PDF, EPUB and Kindle. Book excerpt: A review of this structure and the geological evolution of this region. In addition, an excursion guide that highlights the main geological features of the Vredefort dome and the surrounding region. Illustrates a geological section through the Archaean and Palaeoproterozoic rocks of the Kaapvaal craton, the deformation phenomena and melt breccias related to the impact event, and the metamorphic rocks which have provided important constraints on both the pre- and post-impact thermal evolution of the crust in the region. The significance of the crustal section exposed in the dome for studies of Archaean cratonic crust and the implications of the Vredefort impact event for the evolution of the phenomenal gold deposits of the Witwatersrand basin are also discussed.

This book was released on 1998 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although it is known that what ultimately drives metamorphism is heat, what is less certain is the distribution of heat within the crust and the rates of heat flux through crustal rocks. This text explores the factors that control metamorphism and the rates of metamorphic processes.
