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.

Product Description: 1.1. HISTORICAL DEVELOPMENT OF THE OPHIOLITE CONCEPT. Ophiolite, Greek for 'the snake stone', appears to have received its first written definition by Brongniart (1813) as a serpentine matrix containing various minerals. Later in 1821 and 1827, Brongniart determined that volcanic and gabbroic rocks were also present, associated with cherts, and he ascribed an igneous origin to the ophiolite...read more

Product Description: Although the great diversity of alkaline rocks, with their tion of alkaline rocks and carbonatites with rifting has long been acknowledged. However, many large, diverse relatively exotic rnineralogies. has always attracted the interest of petrologists, as have the more recently defined and important provinces are not widely known, includ­ carbonatites, it could be argued that little progress has ing the 20 or so major provinces of the U...read more

Product Description: This volume illustrates some of the significant aspects of magmatic activity from Devonian (408 million years ago) to early Permian (270 million years ago) times in SW England. This period covers the progressive development of the Variscan mountain-building episode, from initial basin formation to final deformation and the subsequent development of a fold mountain belt - the Variscan Orogen...read more

Product Description: Alkaline rocks and carbonatites have the most varied and extreme compositions of all igneous rocks. This volume describes all the known occurrences in the former USSR.

Product Description: There are several books emphasizing the mineralogical and petrological aspects of granites, but this book is the only one emphasizing the experimental aspects.

This text, designed for the middle-level undergraduate geology major, incorporates both fundamentals and information on recent advances in our understanding of igneous, sedimentary, and metamorphic rocks. It provides an overview of the field of petrology and a solid foundation for more advanced studies. For each class of rocks -- igneous, sedimentary, and metamorhic -- the author describes textures, structures, mineralogy, chemistry, and classification as a background to discussing representative occurrences and petrogenesis (rock origins).

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.

Progress in Metamorphic and Magmatic Petrology comprises a collection of review articles summarising recent scientific achievements in the theory of petrology. The contributors include many prominent specialists in the field, such as A. Boettcher, A. Marakushev, I. Kushiro, B. Mysen, W. Schreyer, W. Ernst, E. Grew, P. Wyllie and E-an Zen. Their papers discuss developments in experimental work as well as in field geology. The book is divided into three main sections: section 1 covers general thermodynamics and mineral equilibria, section 2 covers metamorphic and metasomatic processes, and the final section covers the mantle and magmatic processes. The subjects covered include the general thermodynamics of geological processes, the thermodynamics of solid solutions, geothermometry and geobarometry, P-T-time paths, experimental and theoretical modelling of metasomatic processes, the genesis of anorthosites, island arc magmatic rocks and kimberlites, and the thermal areas around intrusive bodies. The book is dedicated to the memory of Professor D. S. Korzhinskiy, a founder of the theory of open systems with perfectly mobile components. (view table of contents)

Product Description: Decades of field and microscope studies, and more recent quantitative geochemical analyses have resulted in a vast, and sometimes overwhelming, array of nomenclature and terminology associated with igneous rocks. This book presents a complete classification of igneous rocks based on all the recommendations of the International Union of Geological Sciences (IUGS) Subcommission on the Systematics of Igneous Rocks...read more (view table of contents, read Amazon.com's description)

Product Description: This volume presents a unique compendium of papers assessing the effects of volcanism on lakes, as recorded by the volcaniclastic sediments deposited within them. The unifying theme is that the effects of volcanism on lacustrine sedimentation are diverse and distinctive, and that volcaniclastic lacustrine sediments hold the key to understanding a range of processes and events that cannot be readily addressed by the study of any non-volcanic lakes...read more (view table of contents, read Amazon.com's description)

Product 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...read more (view table of contents, read Amazon.com's description)
