Based on hundreds of thin sections from granite in China, this book introduces metasomatic textures and their formation mechanism in granite. It also proposes that metasomatic textures can basically be classified into two patterns: hetero-oriented replacement and co-oriented replacement, according to the consistency of orientations of replacive and replaced minerals. The hetero-oriented albitization of K-feldspar is quite distinct from the co-oriented albitization of K-feldspar. They occur separately without transition, although both are generally referred to as albitization of K-feldspar.This unique granite atlas uses a series of color microphotos taken with a quartz plate under crossed polars to clearly illustrate metasomatic mechanisms and superimposed metasomatic processes. The origins of clear albite rim, intergranular swapped albite, K-feldspathization, quartzification, muscovitization, beryllization, myrmekite, small platy albite, perthitic albite, K-feldspar megacryst etc. are comprehensively discussed and explained. The book will appeal to teachers, researchers and students involved in igneous and metamorphic petrology.

This volume brings together a collection of papers that summarize current ideas and recent progress in the study of granite-related mineralization systems. They provide a combination of field, experimental and theoretical studies. Papers are grouped according to the main granite-related ore systems: granite-pegmatite, skarn and greisen-veins, porphyry, orogenic gold, intrusion-related, epithermal and porphyry-related gold and base metal, iron oxide-copper-gold (IOCG), and special case studies. The studies provide a broad spread in terms of both space and time, highlighting granite-related ore deposits from Europe (Russia, Sweden, Croatia and Turkey), the Middle East (Iran), Asia (Japan and China) and South America (Brazil and Argentina) and spanning rocks from Palaeoproterozoic to Miocene in age.

This book is focused on the basics of applying thermochronology to geological and tectonic problems, with the emphasis on fission-track thermochronology. It is conceived for relatively new practitioners to thermochronology, as well as scientists experienced in the various methods. The book is structured in two parts. Part I is devoted to the fundamentals of the fission-track method, to its integration with other geochronologic methods, and to the basic principles of statistics for fission-track dating and sedimentology applied to detrital thermochronology. Part I also includes the historical development of the technique and thoughts on future directions. Part II is devoted to the geological interpretation of the thermochronologic record. The thermal frame of reference and the different approaches for the interpretation of fission-track data within a geological framework of both basement and detrital studies are discussed in detail. Separate chapters demonstrate the application of fission-track thermochronology from various perspectives (e.g., tectonics, petrology, stratigraphy, hydrocarbon exploration, geomorphology), with other chapters on the application to basement rocks in orogens, passive continental margins and cratonic interiors, as well as various applications of detrital thermochronology.

Metamorphic Textures provides definitions, descriptions and illustrations of metamorphic textures, as well as the fundamental processes involved in textural development. This book is composed of 11 chapters and begins with a presentation of the metamorphic processes and the production of metamorphic minerals. The subsequent chapters describe the structural classification of grain boundaries, the metamorphic reactions, mineral transformations, and the crystallization and recrystallization of metamorphic rocks. These topics are followed by the texture examination of thermal metamorphic rocks and minerals and the preferred orientations of these rocks, particularly the dimensional and lattice preferred orientation. Other chapters survey the textures of rocks under dynamic and shock metamorphism. The final chapters describe the textures of regional and polymetamorphism. This book will be of great use to petrologists, physicists, and graduate and undergraduate petrology students.

Mind over Magma chronicles the scientific effort to unravel the mysteries of rocks that solidified on or beneath Earth's surface from the intensely hot, molten material called magma. The first-ever comprehensive history of the study of such igneous rocks, it traces the development of igneous petrology from ancient descriptions of volcanic eruptions to recent work incorporating insights from physical chemistry, isotope studies, and fluid dynamics. Intellectual developments in the field--from the application of scientific methods to the study of rocks to the discovery of critical data and the development of the field's major theories--are considered within their broader geographical, social, and technological contexts. Mind over Magma examines the spread of igneous petrology from western Europe to North America, South Africa, Japan, Australia, and much of the rest of the world. It considers the professionalization and Anglicization of the field, detailing changes in publication outlets, the role of women, and the influence of government funding. The book also highlights the significant role that technological developments--including the polarizing microscope, high-temperature quenching furnaces, and instrumental analysis--have played in the discovery of new data and development of revolutionary insights into the nature of igneous rocks. Both an engagingly told story and a major reference, Mind over Magma is the only available history of this important field. As such, it will be appreciated by petrologists, geochemists, and other geologists as well as by those interested in the history of science.

The variety of volcanic activity in the Solar System is widely recognised, yet the majestic sequences of magmatic processes that operate within an active planet are much less well known. Providing an exposition of igneous rocks, magmas and volcanic erupsions, this book brings together magnetic and volcanic data from different tectonic settings, and planets, with explanations of how they fit together. It systematically examines composition, origin and evolution of common igneous rocks, yet also examines a variety of rare magnetic rocks that play a crucial role in the global magma/igneous rock system.
