Geophysical data relating the dynamic processes of plate motion and subduction to Andean orogenesis are interpreted in terms of a new model for magmatic and tectonic development of the central Andes. The model is based on changing subduction geometry - from normal to flat to normal - and the attendant magmatic and tectonic effects of slab dewatering, continental lithospheric hydration, and asthenospheric flow during closing and opening of the subduction zone mantle wedge.

The present volume Stratabound Ore Deposits in the Andes has its roots in an international seminar on stratabound ore deposits which took place in September 1986 in Cusco, Peru, sponsored by Multi ciencias (Peru) and UNESCO. During this seminar it became clear that the amount and quality of research done on stratabound ore deposits in the Andes required a synthesis. Researchers in industry and government as well as in academia, including many which had participated at the Cusco Seminar, were invited to contribute. The answer was extremely positive, confirming the idea that a book expressing the state of the art of the study of stratabound ore deposits in the Andes was long overdue. As editors we sought to give maximum coverage to the present knowledge, yet keeping the length, and thereby the price, within rea sonable limits. The book contains three types of contributions. In the first part the reader will find review papers focusing on ( 1) the geologic framework (Frutos), (2) the metallogenesis in Andean countries including also types of deposits differing from those of stratabound nature (Cardozo and Cedillo, Oyarzun), and (3) an in troductory overview of the stratabound ore deposits in the Andes, emphasizing their geotectonic position as a classification tool (Font bote).

"The objective of this volume is to examine the Cenozoic tectonic and magmatic evolution from the arc to the retroarc of a distinctive end-member of the Andean accretionary orogen between 35*S and 39*S. The evolution of the Andes in this region provides an outstanding case study of an orogen where periods of contraction and extension, crustal shortening and normal faulting, and differences in retroarc volcanism reflect a tectonic regime that alternates in space and time. Structural, magmatic, and paleogeographic patterns correlate strongly with the dynamics of the subduction zone. The region includes the Neuquen basin which is one of the most prolific of the Central Andes. The tectonic setting is important in understanding hydrocarbon systems of the sub-Andean basin and the potential for ore deposits in the cordillera. The book is fundamental for researchers working on tectonics and magmatism in Andean type systems as well as those involved in exploration."--Publisher's website.

"The American Cordilleras form a continuous orogen that extends for 12,500 km along the eastern flank of the Pacific Ocean from Arctic to Antarctic latitudes as an integral part of the circum-Pacific orogenic belt. Following two summary chapters on the overall anatomy and evolution of North and South American segments of the orogenic system, this volume includes ten seminal chapters dealing with salient aspects of the key geodynamic processes that have accompanied Cordilleran geotectonic evolution: forearc terrane accretion, arc magmatism, shallow subduction, and backarc intracontinental deformation. The papers in this volume were selected from those presented at the 2006 Backbone of the Americas Meeting, which was sponsored jointly by multiple North and South American geological societies in Mendoza, Argentina."--pub. desc.

This Special Publication arises from the UNESCO-sponsored IGCP 586-Y project `The tectonics and geomorphology of the Andes (32°–34°S): interplay between short-term and long-term processes’. It includes state-of-the-art reviews and original articles from a multidisciplinary perspective that investigate the complex interactions of tectonics and surface processes in the subduction-related orogen of the Andes of central Chile and Argentina (c. 27° –39°S). It aims to improve our understanding of tectonic and landscape evolution of the Andean range at different time scales, as well as the mutual relationship between internal and external mechanisms in Cenozoic deformation, mountain building, topographic evolution, basin development and mega-landslides occurrence across the flat slab to normal subduction segments. The geodynamic processes of the Andes of central Chile and Argentina are analysed from a number of subdisciplines of the Earth sciences, including tectonics, petrology, geophysics, geochemistry, structural geology, geomorphology, engineering geology, stratigraphy and sedimentology.

The book Cenozoic Geology of the Central Andes of Argentina, prepared within the context of Instituto del Cenozoico at Universidad Nacional de Salta, is thus a compendium of 27 original contributions containing extensive work on the multiple aspects of Andean geology of the past 65 million years. Each study has been responsibly peer-reviewed, thoroughly edited and carefully presented.

"This memoir brings together results from a multidisciplinary study of the processes that have formed the highest, widest part of the Andean Cordilleran orogenic belt in northern Argentina and Chile. The region features a tectonically erosive forearc, protracted arc magmatism, a high-elevation hinterland plateau and strongly shortened retroarc thrust belt, and a Paleocene-Recent foreland basin system"--

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.

This book is the first comprehensive account in English of the geology of Chile, providing a key reference work that brings together many years of research, and written mostly by Chilean authors from various universities and other centres of research excellence. The 13 chapters begin with a general overview, followed by detailed accounts of Andean tectonostratigraphy and magmatism, the amazingly active volcanism, the world class ore deposits that have proven to be so critical to the welfare of the country, and Chilean water resources. The subject then turns to geophysics with an examination of neotectonics and earthquakes, the hazardous frequency of which is a daily fact of life for the Chilean population. There are chapters on the offshore geology and oceanography of the SE Pacific Ocean, subjects that continue to attract much research not least from those seeking to understand world climatic variations, and on late Quaternary land environments, concluding with an account examining human colonization of southernmost America. The geological evolution of Chile is the c. 550 million year history of a continental margin over 4000 km long. During his voyage on H.M.S. Beagle, an extended visit to Chile (1834-35) had a profound impact on Charles Darwin, especially on his understanding of volcanoes, earthquakes and tsunamis.

The Central Andean Altiplane represents a unique extreme environment due to its high altitude, closed basins that modulate the salt pans and saline wetlands surrounded by deserts, as well as the considerable influence of volcanic activity. UV radiation, arsenic content, high salinity, alkalinity and low dissolved oxygen levels, together with extreme daily temperature fluctuations and oligotrophic conditions, shape an environment that resembles the early Earth and, even more, extraterrestrial conditions. By developing simple biofilms stratified microbial mats or complex microbialites, extreme microbial ecosystems, colonize and thrived in different environments like salt flats, wetlands, lakes volcano vents, geysers and deserts. This book presents our current understanding of these amazing ecosystems, providing a basis for their protection and sustainable utilization. The main audience for this book included researchers and graduate students as well as professionals working in the government, mining industry and similar activities.
