This volume gives an overview of the geotectonic evolution of the Central Andes. The contributions cover the whole spectrum of geoscientific research: geology, petrology, geochemistry, geophysics and geomorphology. They deal with the period from late Precambrium up to the youngest phenomena in the Quaternary. The book is of value for regional geologists as well as for scientists interested in orogenic processes related to active continental margins.
