The second half of the past century witnessed a remarkable paradigm shift in approach to the understanding of igneous rocks. Global literature records a change from a classical petrographic approach to emphasis on mineral chemistry, trace element characteristics, tectonic setting, phase relations, and theoretical simulation of magma generation and evolution processes. This book contains contributions by international experts in different fields of igneous petrology and presents an overview of recent developments. This book is dedicated to the late Dr Mihir K. Bose, former professor of the Department of Geology, Presidency College, Calcutta, India, who actively participated in the development of this new global view of igneous petrology.
A concise introduction to the mineralogy and petrology of igneous and metamorphic rocks for all Earth Science students.
Concise introductory textbook on the petrology of igneous and metamorphic rocks for one-semester courses. Topics are organized around the types of rocks to expect in tectonic environments, rather than around rock classifications. Application boxes engage students by showing how petrology connects to wider aspects of geology. Includes end-of-chapter exercises.
Igneous petrology was to some extent essentially a descriptive sci ence until about 1960. The results were mainly obtained from field work, major element analyses, and microscopical studies. During the 1960's two simultaneous developments took place, plate tectonics became generally accepted, and the generation of magmas could now be related to the geodynamic features like convection cells and subduction zones. The other new feature was the development of new analytical apparatus which allowed high accuracy analyses of trace elements and isotopes. In addition it became possible to do ex perimental studies at pressures up to 100 kbar. During the 1970's a large amount of analytical data was obtained and it became evident that the igneous processes that control the compositions of magmas are not that simple to determine. The composition of a magma is controlled by the compositions of its source, the degree of partial melting, and the degree of fractionation. In order to understand the significance of these various processes the relationship between the physical processes and their geochemical consequences should be known. Presently there are several theories that attempt to explain the origin of the various magma types, and these theories can only be evaluated by turning the different ideas into quantitative models. We will so to speak have to do some book keeping for the various theories in order to see which ones are valid. the present book is intended as an introduction to the more fun damental aspects of quantitative igneous petrology.
As a major text in igneous petrology, this innovative book offers a much-needed, radically different approach to the study of igneous rocks. Bridging a long-recognized gap in the literature by providing petrogenic models for magmatismin terms of global tectonic processes, it encompasses geophysics and geochemistry in a comprehensive treatment of the subject. Most textbooks in igneous petrology have intended to avoid discussion of potentially controversial petrogenetic models. However, this is precisely the sort of information senior students of igneous petrology require. Dr Wilson has drawn on 15 years of research and 10 years of teaching experience in writing an account of what is now a well established understanding of the processes involved in environments of magma generation. She provides full discussions of the major-element, trace-element, and radiogenic isotope characteristics of magmas generated in different tectonic settings and she deals with the information derived from such data concerning magma source regions and their ascent trough the Earth's lithosphere. Additionally each chapter contains a summary of geophysical data relating to crustal and mantle structure and the location of magma reservoirs. The modular format of the book will facilitate its use by all students, researchers and professionals with an interest in igneous petrology. A basic knowledge of geochemistry, mineralogy, phase diagrams, regional geology and global tectonics is assumed, but such advanced topics as trace element and isotope geochemistry can be omitted initially if the reader's background is inappropriate. The text is profusely illustrated and the bibliography contains over 1000 carefully selected references. Marge Wilson graduated in geology at the University of Oxford. She then spent a year at the University of California, Berkeley, and subsequently studied the petrogenesis of nepheline syenites from the Gardar province of Greenland, leading to a PhD from the University of Leeds. Her research has focused on island-arc, oceanic-island and intra-continental plate tectonic settings.
A textbook providing a quantitative approach to the petrologic principles of igneous and metamorphic rocks in a new edition.
Igneous Petrology provides up-to-date, integrated, comprehensive coverage of physical and chemical facets of magmatic rocks and magma systems. Field relations and fabrics of rocks together with their mineralogical, chemical and isotopic compositions facilitate interpretation of rock origin. The dynamic evolution of magma systems is considered from thermodynamics and from their chemical, physical and kinetic properties. Sources of magmas and how they are generated and subsequently evolve are considered in the context of global tectonics. The textbook stresses petrologic processes while also providing thorough descriptions of rock products suitable for the undergraduate student. Organized in terms of chemical and physical phenomena. Includes new insights into intrusive and volcanic processes-especially, explosive volcanism in field petrology. Contains new data in physical petrology. Focuses on the latest research of magma properties and experimental and theoretical modeling. Consists of new coverage of trace element characterization of rock associations and modeling. Well illustrated text with a 6-page, 4-color insert. For ease of use, the quantitative material is set aside in boxes and in certain chapters. Features "Fundamental questions considered in the chapter" which provide a brief, chapter preview. "Critical thinking questions" allow the students to expand their command of the subject. Contains a comprehensive glossary along with a list of cited references. Additional problem sets will be available on the web.
Introduction to Mineralogy and Petrology, second edition, presents the essentials of both disciplines through an approach accessible to industry professionals, academic researchers, and students alike. This new edition emphasizes the relationship between rocks and minerals, right from the structures created during rock formation through the economics of mineral deposits. While petrology is classified on the lines of geological evolution and rock formation, mineralogy speaks to the physical and chemical properties, uses, and global occurrences for each mineral, emphasizing the need for the growth of human development. The primary goal is for the reader to identify minerals in all respects, including host-rocks, and mineral deposits, with additional knowledge of mineral-exploration, resource, extraction, process, and ultimate use. To help provide a comprehensive analysis across ethical and socio-economic dimensions, a separate chapter describes the hazards associated with minerals, rocks, and mineral industries, and the consequences to humanity along with remedies and case studies. New to the second edition: includes coverage of minerals and petrology in extra-terrestrial environments as well as case studies on the hazards of the mining industry. Addresses the full scope of core concepts of mineralogy and petrology, including crystal structure, formation and grouping of minerals and soils, definition, origin, structure and classification of igneous, sedimentary and metamorphic rocks Features more than 250 figures, illustrations and color photographs to vividly explore the fundamental principles of mineralogy and petrology Offers a holistic approach to both subjects, beginning with the formation of geologic structures that is followed by the hosting of mineral deposits and the exploration and extraction of lucrative, usable products that improve the health of global economies Includes new content on minerals and petrology in extraterrestrial environments and case studies on hazards in the mining industry
The field of Igneous Petrology has evolved greatly in the past years. McBirney's new Third Edition, completely revised and updated, presents a modern and integrated survey of the geological and genetic relations of igneous rocks. It illustrates how modern geochemical and geophysical methods can be combined with field relations to understand the generational and compositional evolution of magmas.
A balanced text that bridges the gap between introductory petrography-oriented texts and the more advanced texts that have a thermodynamic and/or chemical approach. Well-indexed, well-referenced and written in a particularly readable style, it leads the reader from classical to modern concepts in igneous petrology.
