This book provides the first comprehensive overview of a complete subduction orogen, the Andes, considered to represent the "type" subduction belt on Earth. Integrating the results from a wide variety of methods it provides the most compact and highly resolved geophysical image of an active subduction orogen complimented by detailed geodetic data and a range of geological observations. This allows the derivation of a sophisticated process-oriented understanding of the mechanisms driving subduction orogeny's in their various manifestations. The results of 12 years of integrated multi-disciplinary research is presented including a DVD containing maps, geological sections, geophysical results and a data archive.
