Book Description
This book is mainly about the field geology of granites at all scales from that of a single outcrop to plutons and batholiths. All field geologists work initially at the scale of the outcrop, consequently most of the phenomena treated herein are those which are visible at outcrop scale. However, granites typically occur as plutons and batholiths, some of which are so large as to apparently defy any effort at systematic treatment. Having had the opportunity of mapping two very large and very different batholiths, namely the Coastal Batholith of Peru and the tin granites of Southeast Asia, I have found that it is possible to map large batholiths within a relatively short time, so that the geology of the batholith as a whole can be appreciated. Moreover batholiths are one of the most common modes of granite occurrence, so it makes sense to study them at their natural scale. During my working life I have worked with many geologists from underdevel oped countries and this book is mainly to help them in unravelling the geology of their native batholiths. I have been lucky with my friends and colleagues of many nationalities, and I particularly thank Wallace Pitcher, who took me on as an untried apprentice in Peru, and who, by his kindness and example, showed me how to look at granites properly.

Book Description
viii debate of those earlier days has been beautifully summarized by H. H. Read in his famous "Granite Controversy" (1957). Read's formulation of the controversy occurred at the time when geochemistry was as a new and powerful tool. The new techniques opened era during which emerging an granites were considered mainly from this new viewpoint. Geochemical signatures have shown that mantle and crustal origins for granites were both possible, but the debate on how and why granites are emplaced did not progress much. Meanwhile, structural geology was essentially geometrical and mechanistic. In the early 70's, the structural approach began to widen to include solid state physics and fluid dynamics. Detailed structural maps of granitic bodies were again published, mainly in France, and analysed in terms of magmatic and plastic flow. The senior editor of this volume and his students deserve much of the credit for this new development. Via microstructural and petrofabric studies, they were able to discriminate between strain in the presence of residual melt or in the solid-state, and, by systematically measuring magnetic fabrics (AMS), they have been able to map magmatic foliations and lineations in ever finer detail, using the internal markers within granites coming from different tectonic environments. The traditional debate has been shifted anew. The burning question now seems to be how the necessary, large-scale or local, crustal extension required for granite emplacement can be obtained.

Book Description
The Plastic Turn offers a novel way of looking at plastic as the defining material of our age and at the plasticity of plastic as an innovative means of understanding the arts and literature. Ranjan Ghosh terms this approach the material-aesthetic and, through this concept, traces the emergence and development of plastic polymers along the same historical trajectory as literary modernism. Plastic's growth as a product in the culture industry, its formation through multiple application and chemical syntheses, and its circulation via oceanic movements, Ghosh argues, correspond with, and offers novel insights into, developments in modernist literature and critical theory. Through innovative readings of canonical modernist texts, analyses of art works, and accounts of plastic's devastating environmental impact, The Plastic Turn proposes plastic's unique properties and destructive ubiquity as a "theory machine" to explain literature and life in the Anthropocene. Introducing several new concepts (like plastic literature, plastic literary, etc.) into critical-humanist discourse, Ghosh enmeshes literature and theory, materiality and philosophy, history and ecology, to explore why plastic as a substance and as an idea intrigues, disturbs, and haunts us.

Book Description
The origin of granite has for long fascinated geologists though serious debate on the topic may be said to date from a famous meeting of the Geological Society of France in 1847. My own introduction to the subject began exactly one hundred years later when, in an interview with Profes sor H. H. Read, I entered his study as an amateur fossil collector and left it as a committed granite petrologist - after just ten minutes! I can hardly aspire to convert my reader in so dramatic a way, yet this book is an attempt, however inadequate, to pass on the enthusiasm that I inherited, and which has been reinforced by innumerable discussions on the outcrop with granitologists of many nationalities and of many shades of opinion. Since the 1960s, interest in granites has been greatly stimulated by the thesis that granites image their source rocks in the inaccessible deep crust, and that their diversity is the result of varying global tectonic context. So great a body of new data and new ideas has accumulated that my attempt to review the whole field of granite studies must carry with it a possible charge of arrogance, especially as I have adopted the teaching device of presenting the material from a personal point of view with its thinly disguised prejudices.

Book Description
The United States Military Academy at West Point is one of America’s oldest and most revered institutions. Founded in 1802, its first and only mission is to prepare young men—and, since 1976, young women—to be leaders of character for service as commissioned officers in the United States Army. West Point’s success in accomplishing that mission has secured its reputation as the foremost leadership-development institution in the world. An Academy promotional poster says it this way: “At West Point, much of the history we teach was made by people we taught.” Carved from Granite is the story of how West Point goes about producing military leaders of character. An opening chapter on the Academy’s nineteenth-century history provides context for the topic of each subsequent chapter. As scholar and Academy graduate Lance Betros shows, West Point’s early history is interesting and colorful, but its history since then is far more relevant to the issues—and problems—that face the Academy today. Drawing from oral histories, archival sources, and his own experiences as a cadet and, later, a faculty member, Betros describes and assesses how well West Point has accomplished its mission. And, while West Point is an impressive institution in many ways, Betros does not hesitate to expose problems and challenge long-held assumptions. In a concluding chapter that is both subjective and interpretive, the author offers his prescriptions for improving the institution, focusing particularly on the areas of governance, admissions, and intercollegiate athletics. Photographs, tables, charts, and other graphics aid the clarity of the discussion and lend visual and historical interest. Carved from Granite: West Point since 1902 is the most authoritative history of the modern United States Military Academy written to date. There will be lively debate over some of the observations made in this book, but if they are followed, the author asserts that the Academy will emerge stronger and better able to accomplish its vital mission in the new century and beyond.

Book Description
Granites (sensu lato) represent the dominant rock-type forming the upper–middle continental crust but their origin remains a matter of long-standing controversy. The granites may result from fractionation of mantle-derived basaltic magmas, or partial melting of different crustal protoliths at contrasting P–T conditions, either water-fluxed or fluid-absent. Consequently, many different mechanisms have been proposed to explain the compositional variability of granites ranging from whole igneous suites down to mineral scale. This book presents an overview of the state of the art, and envisages future avenues towards a better understanding of granite petrogenesis. Particular emphasis of this Volume is on the following topics: Compositional variability of granitic rocks generated in contrasting geodynamic settings during Proterozoic to Phanerozoic Periods, Main permissible mechanisms producing subduction-related granites, Crustal anatexis of different protoliths, and the role of water in granite petrogenesis, New theoretical and analytical tools available for modelling whole-rock geochemistry, in order to decipher the sources and evolution of granitic suites.

Book Description
The true story behind the events that inspired the major motion picture Only the Brave. A "unique and bracing" (Booklist) first-person account by the sole survivor of Arizona's disastrous 2013 Yarnell Hill Fire, which took the lives of 19 "hotshots" -- firefighters trained specifically to battle wildfires. Brendan McDonough was on the verge of becoming a hopeless, inveterate heroin addict when he, for the sake of his young daughter, decided to turn his life around. He enlisted in the Granite Mountain Hotshots, a team of elite firefighters based in Prescott, Arizona. Their leader, Eric Marsh, was in a desperate crunch after four hotshots left the unit, and perhaps seeing a glimmer of promise in the skinny would-be recruit, he took a chance on the unlikely McDonough, and the chance paid off. Despite the crew's skepticism, and thanks in large part to Marsh's firm but loving encouragement, McDonough unlocked a latent drive and dedication, going on to successfully battle a number of blazes and eventually win the confidence of the men he came to call his brothers. Then, on June 30, 2013, while McDonough -- "Donut" as he'd been dubbed by his team--served as lookout, they confronted a freak, 3,000-degree inferno in nearby Yarnell, Arizona. The relentless firestorm ultimately trapped his hotshot brothers, tragically killing all 19 of them within minutes. Nationwide, it was the greatest loss of firefighter lives since the 9/11 attacks. Granite Mountain is a gripping memoir that traces McDonough's story of finding his way out of the dead end of drugs, finding his purpose among the Granite Mountain Hotshots, and the minute-by-minute account of the fateful day he lost the very men who had saved him. A harrowing and redemptive tale of resilience in the face of tragedy, Granite Mountain is also a powerful reminder of the heroism of the people who put themselves in harm's way to protect us every day.
