Evolution of an Andean margin: a tectonic and magmatic view from the Andes to the Neuquén Basin (35 degrees-39 degrees S lat)

This work presents new data and ideas on the post-Mesozoic evolution of the Neuquén Basin. These studies have led to major steps in understanding the arc and retroarc evolution of this distinctive segment of the Andes, and are collected here as a complement to the literature on the young volcanic centers of the Southern Volcanic Zone arc, and to a book titled The Neuquén Basin: A case study in sequence stratigraphy and basin dynamics (published by the Geological Society of London). Topics explored include major revisions in the timing of Mesozoic and Cenozoic magmatic and deformational events in the arc and retroarc, the importance of pre-Tertiary structures in controlling younger deformational styles, and transient Miocene shallowing of the Andean subduction zone in association with development of Laramide-style magmatism. Numerous b&w and color maps and photos are included. Kay is affiliated with Cornell University. Ramos is affiliated with the University of Buenos Aires. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com) 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.
