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

This special volume stems from a symposium 'Granitic Systems - State of the Art and Future Avenues' that was held at the Department of Geology, University of Helsinki to mark the retirement of Professor Ilmari Haapala. The twenty articles in the volume cover a wide range of granite-related topics and focus on three general themes: tectonics and source regions, petrologic processes, and fractionated granites and pegmatites. Both original papers and reviews are included, and the volume will be acknowledged by anyone with a background in Earth Sciences ad a flavor for granitoid rocks. * Comprehensive account of the current status of granite-oriented research * Topics ranging from mineralogy, petrology, and geochemistry to tectonics and crustal evolution

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.

A compilation of landmark papers on granite petrogenesis is overdue. This volume is organized into a number of sections that represent what the editors regard as the main research fields in which progress has been made in understanding granites and their genesis. The origin of granitic magmas is part of the cycle that unites tectonic processes with the generation of mantle magma, crustal growth, the transfer of mantle heat to the crust, high-grade regional metamorphism, crustal melting and crustal differentiation. The extended subject area is far too wide to deal with in a single volume and therefore the selection has been limited to papers dealing with the formation, physical behaviour and chemical evolution of granitic magmas, and just touching on the matter of associated ore deposits. John (JC) Clemens and Fernando Bea are world experts on the subject of granite petrogenesis. Clemens' most important work has been on the origin and evolution of granites and silicic volcanic magmas, experimental studies and modelling of partial melting and the ascent and chemical evolution of granitic magmas, and these continue to be his main interests. Bea's research interests have been in the petrology and geochemistry of granite rocks and the mechanisms of generation of granite magmas, having studied in detail the role of heat-producing elements.

Metamorphic rocks are one of the three classes of rocks. Seen on a global scale they constitute the dominant material of the Earth. The understanding of the petrogenesis and significance of metamorphic of geological education. rocks is, therefore, a fundamental topic There are, of course, many different possible ways to lecture on this theme. This book addresses rock metamorphism from a relatively pragmatic view point. It has been written for the senior undergrad uate or graduate student who needs practical knowledge of how to interpret various groups of minerals found in metamorphic rocks. The book is also of interest for the non-specialist and non-petrolo gist professional who is interested in learning more about the geolo gical messages that metamorphic mineral assemblages are sending, as well as pressure and temperature conditions of formation. The book is organized into two parts. The first part introduces the different types of metamorphism, defines some names, terms and graphs used to describe metamorphic rocks, and discusses principal aspects of metamorphic processes. Part I introduces the causes of metamorphism on various scales in time and space, and some principles of chemical reactions in rocks that accompany metamorphism, but without treating these principles in detail, and presenting the thermodynamic basis for quantitative analysis of reactions and their equilibria in metamorphism. Part I also presents concepts of metamorphic grade or intensity of metamorphism, such as the metamorphic-facies concept.
