This work covers the subject of the petrology of the metamorphic rocks, including such subjects as rock and mineral compositions and their relationship, metamorphism associated with igneous intrusions, dynamic metamorphism, extra-terrestrial metamorphism and metamorphism in collision zones. The book uses examples of the field relationships of metamorphic rocks and their appearance in thin section; discusses the thermodynamic and analytic methods concerned; describes methods for determining the temperatures and deformations of the rocks and demonstrates how thermodynamic modelling enables them to be interpreted as the outcome of plate tectonics.

This book explores and analyzes how the Arab Spring has affected the political and economic relationships between the West, the BRICs (Brazil, Russia, India, China, and South Africa) and the MENA (Middle Eastern and North African states). It locates continuity and change in these relations within the broader context of democratization, energy, security, arms relationships, and the shift towards a multi-polar system. Each chapter charts a history of ideological engagement, which has generally given way to more pragmatic energy, economic, and security interests, and defines and analyzes the fundamental and emerging factors that shape foreign policy. The volume pays special attention to the UN Security Council authorization of "all necessary measures" against Qaddafi's Libya and the subsequent deadlock in getting China and Russia to pass further Resolutions for intervention in Syria.

There has been a great advance in the understanding of processes of meta­ morphism and of metamorphic rocks since the last edition of this book appeared. Methods for determining temperatures and pressures have become almost routine, and there is a wide appreciation that there is not a single temperature and pressure of metamorphism, but that rocks may preserve, in their minerals, chemistry and textures, traces of their history of burial, heating, deformation and permeation by fluids. However, this excit­ ing new knowledge is still often difficult for non-specialists to understand, and this book, like the first edition, aims at enlightenment. I have concen­ trated on the interpretation of the plate tectonic settings of metamorphism, rather than following a geochemical approach. Although there is an impress­ ive degree of agreement between the two, I believe that attempting to discover the tectonic conditions accompanying rock recrystallization will more readily arouse the interest of the beginner. I have used a series of case histories, as in the first edition, drawing on my own direct experience as far as possible. This m
