Igneous Rocks And Processes

IGNEOUS ROCKS AND PROCESSES A practical introduction to igneous petrology for students and practitioners The newly revised Second Edition of Igneous Rocks and Processes: A Practical Guide, delivers an authoritative introduction to igneous petrology and helps students to develop key skills and confidence in identifying igneous materials and in naming and interpreting unknown igneous rocks presented to them. It serves as both a conventional course text and a practical laboratory manual. The authors review igneous nomenclature and subsequently describe specific compositional categories of magmatic rocks. Each chapter covers definitions, mineralogy, eruption and emplacement processes, textures and crystallization processes, geotectonic distribution, geochemistry, and aspects of magma genesis. Additional chapters address phase equilibrium experiments and physical volcanology. This latest edition offers readers extensively updated chapters, as well as access to a companion website with supplementary material. It also provides: Thorough introductions to magmas, magmatic rocks, and magma differentiation Exercises for each chapter, with answers provided at the end A detailed summary of techniques and optical data for mineral identification using a polarizing microscope An introduction to petrographic calculations and an extensive glossary Perfect for geoscience students taking courses in igneous petrology, Igneous Rocks and Processes: A Practical Guide, second edition will also earn a place in the libraries of postgraduate students and researchers in the field.

This book is for geoscience students taking introductory or intermediate-level courses in igneous petrology, to help develop key skills (and confidence) in identifying igneous minerals, interpreting and allocating appropriate names to unknown rocks presented to them. The book thus serves, uniquely, both as a conventional course text and as a practical laboratory manual. Following an introduction reviewing igneous nomenclature, each chapter addresses a specific compositional category of magmatic rocks, covering definition, mineralogy, eruption/ emplacement processes, textures and crystallization processes, geotectonic distribution, geochemistry, and aspects of magma genesis. One chapter is devoted to phase equilibrium experiments and magma evolution; another introduces pyroclastic volcanology. Each chapter concludes with exercises, with the answers being provided at the end of the book. Appendices provide a summary of techniques and optical data for microscope mineral identification, an introduction to petrographic calculations, a glossary of petrological terms, and a list of symbols and units. The book is richly illustrated with line drawings, monochrome pictures and colour plates. Additional resources for this book can be found at: http://www.wiley.com/go/gill/igneous.

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.

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.

Volume 24 of Reviews in Mineralogy attempted to bring together the basic data and fundamental theoretical constraints on magmatic processes with applications to specific problems in igneous petrology. The Mineralogical Society of America (MSA) sponsored the short course on "Modern Methods of Igneous Petrolgy: Understanding Magmatic Processes" at the Cathedral Hill Hotel in San Francisco, California in December 1990. It was organized by the editors, Jim Nicholls and Kelly Russell, and presented by the authors of this volume to about 80 participants in conjunction with the Fall Meeting of the American Geophysical Union.

Even the most recent texts lines, based on the classification of igneous rocks, place very little emphasis on the geochemistry of descriptive petrography, volcanic landforms, types magmas erupted in different tectonic settings, of igneous intrusions and regional petrology . despite extensive discussions of the processes re However, the geologist of the late 1980s requires, in sponsible for the chemical diversity of magmas.

Quantifying the timescales of current geological processes is critical for constraining the physical mechanisms operating on the Earth today. Since the Earth’s origin 4.55 billion years ago magmatic processes have continued to shape the Earth, producing the major reservoirs that exist today (core, mantle, crust, oceans and atmosphere) and promoting their continued evolution. But key questions remain. When did the core form and how quickly? How are magmas produced in the mantle, and how rapidly do they travel towards the surface? How long do magmas reside in the crust, differentiating and interacting with the host rocks to yield the diverse set of igneous rocks we see today? How fast are volcanic gases such as carbon dioxide released into the atmosphere? This book addresses these and other questions by reviewing the latest advances in a wide range of Earth Science disciplines: from the measurement of short-lived radionuclides to the study of element diffusion in crystals and numerical modelling of magma behaviour. It will be invaluable reading for advanced undergraduate and graduate students, as well as igneous petrologists, mineralogists and geochemists involved in the study of igneous rocks and processes.
