This volume discusses the processes that operate during the deformation and metamorphism of rocks in the crust of the earth with the goal of understanding how these processes control or influence the structures that we observe in deformed metamorphic rocks. The deformation and metamorphism of rocks involves structural rearrangements of elements of the rock by processes such as mass diffusion, dislocation slip and climb, disclination and disconnection motion, grain-boundary migration and fracturing at the same time as chemical reactions proceed. In some instances infiltrating fluids introduce or remove chemical components and may influence mechanical properties through changes in volume, fluid pressure or temperature. At the same time, heat is added or removed from the system depending on the surrounding tectonic environment and the processes operating within the deforming rock mass. The intent is to consider these processes within a framework set by both the individual mechanisms of deformation and the fundamental mechanics that describe and relate these mechanisms. Such mechanisms do not operate independently of each other but are strongly coupled so that each process has strong feedback influences on the other leading to structures and mineral assemblages that do not develop in the uncoupled environment. This leads to nonlinear behaviour and so a goal of this book is to treat deforming metamorphic systems as nonlinear dynamic systems. The general system we consider in this book is a deforming, chemically reactive system in which fluid and thermal transports play significant roles. The volume concentrates on the principles that govern the development of deformed metamorphic rocks.
