Resumen:
This book intends to constitute a useful tool to access to data and a discussion about mechanisms that have created the Southern Andes. It is mainly conceived for Earth Science professionals working in academia and industry, as well as PhD students and interested readers in general. The book is structured through a total number of 11 chapters where the two initial are focused in general aspects such as crustal structure and main source areas while the other eight analyze particular mountain sectors ordered from north to south. The book contains maps and cross sections that constitute up-to-date proposals that use previous and new datasets. Different sources are cited at the end of each chapter. The first chapter analyzes from 30 to 55ºS the gravity and magnetic fields with the aim of understanding density and thermal structure of the Southern Andes and adjacent foreland region. The second chapter analyzes the general U/Pb ages of the detrital components of the main sedimentary sections exposed through the different Andean segments. Thus, varying provenance sources through time are discussed, as well as Andean initiation based on changes of detrital compositions on the main sedimentary sections. The third chapter is focused south of the present Pampean flat subduction segment, where a dramatic fall in altitude and amplitude in the Andean orogen is produced. The fourth chapter analyzes the structure and its evolution in the area of the Neuquén embayment. The fith chapter complements this through a detailed description of the development of the fold and thrust belt at 37°S. The sixth chapter analyzes the segment to the south at 39°S where the sag facies of the Neuquén Basin narrow and consequently the structure changes. The seventh chapter focused on the Cenozoic development of the Andes of North Patagonia, while the eighth chapter explores ancient orogenic stages as old as Late Cretaceous in age in this sector. The Ninth chapter constitutes a review about the evolution and structure of the southern Patagonian Andes and finally the tenth chapter focuses on the Fueguian Andes at the southernmost South Americ
