Andean Structural Styles: A Seismic Atlas is a comprehensive reference illustrating the variability in structural styles and hydrocarbon traps that exist in the Andean chain. The Andean chain, stretching over more than 5,000 km (3,000 mi) from Venezuela to Argentina, contains a large number of sedimentary basins which have developed in a wide range of tectonic settings. Some of these basins are highly mature, with hydrocarbon production from Paleozoic, Mesozoic, and Cenozoic sedimentary sequences, while others are still underexplored. Andean Structural Styles: A Seismic Atlas covers topics including fold types, thrust faults, triangle zones, inversion structures, synorogenic deposits, and growth stratal geometries. These topics are illustrated by thirty-two seismic examples interpreted and uninterpreted, covering most of the Andean basins, and five chapters reviewing the structural styles of the Andes, the complexity of processing seismic in these settings, how analogue models help in the interpretation, and several outcrop analogues. This reference is invaluable to both hydrocarbon exploration of the Andes and researchers and students in the fields of exploration geology and structural geology. Also, those teaching structural geology and seismic interpretation will find a valuable resource with lots of uninterpreted seismic examples that can be used in their lectures. - Includes a vast collection of high-quality, color images - Features case studies covering the entirety of the Andes Mountain chain - Presents high-quality seismic data that was previously only available to oil companies

Interpretation of seismic profiles, earthquake fault-plane solutions, radar images, and geometry of structures suggests that two different structural styles are viable alternatives for the Putumayo basin in Colombia. An eastern domain, varying in width from 4 to 13 km, might be characterized by strike-slip faulting parallel to the Andes because it exhibits similar structures to those formed in restraining bend settings, an example is the Orito fold, the largest known oil field in the basin. Correlation of seismic reflections with wells into the Orito fold and foreland indicates a post-Miocene age for this structure. Previous interpretations of contractional dip-slip movement on Andes-parallel structures, as proposed by Portilla (1991) with faults involving basement, are also viable. A 15 km-width western domain is interpreted as a region of foreland-dipping rocks uplifted above their regional level by wedging of pre-Cretaceous (?) rocks beneath known Jurassic rocks. Above the Jurassic rocks thin-skinned deformation occurs inside of the Mesozoic and Cenozoic sedimentary cover, also in the form of wedging. Mesozoic and Paleozoic (?) rocks were injected into of a late Cretaceous-early Paleocene unit composed of shale. The western domain is truncated to the west by a major reverse fault that places Paleozoic rocks over Mesozoic and Cenozoic rocks.

Fold-and-thrust belts occur worldwide, have formed in all eras of geological time, and are widely recognized as the most common mode in which the crust accommodates shortening. Much current research on the structure of fold-and-thrust belts is focused on structural studies of regions or individual structures and on the geometry and evolution of these regions employing kinematic, mechanical and experimental modelling. In keeping with the main trends of current research, this title is devoted to the kinematic evolution and structural styles of a number of fold-and-thrust belts formed from palaeozoic to recent times. The papers included in this book cover a broad range of different topics, from modelling approaches to predict internal deformation of single structures, 3D reconstructions to decipher the structural evolution of groups of structures, palaeomagnetic studies of portions of fold-and-thrust belts, geometrical and kinematical aspects of Coulomb thrust wedges and structural analyses of fold-and-thrust belts to unravel their sequence of deformations--

"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.

"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 book presents recent findings on the structure and evolution of the Southern Andes. Through a detailed description of a series of orogenic segments reviewed by the different groups that have worked with structural and geophysical tools in each area over the last several years, it illustrates the diversity of mechanisms that have impacted strong orogenic gradients and consequently mountain morphology, from the southern Pampean flat subduction zone to the southern tip of the continent (33-56o S). The book also revises our conventional understanding of the source of the different Mesozoic to Cenozoic sections exhumed in the orogenic wedge, with the objective of discussing basin mechanisms through time. A final chapter discusses probable orogenic controls that have acted together in order to explain structure, the different deformational stages and intra-orogenic extensional collapses that affected the fold and thrust belt over time.

Andean Tectonics addresses the geologic evolution of the Andes Mountains, the prime global example of subduction-related mountain building. The Andes Mountains form one of the most extensive orogenic belts on Earth, spanning approximately an 8,000-km distance along the western edge of South America, from ~10°N to ~55°S. The tectonic history of the Andes involves a rich record of diverse geological processes, including crustal deformation, magmatism, sedimentary basin evolution, and climatic interactions. This book addresses the range of Andean tectonic processes and their temporal and spatial variations. An improved understanding of these processes is fundamental not only to the Andes but also to other major orogenic systems associated with subduction of the oceanic lithosphere. Andean Tectonics is a critical resource for researchers interested in the causes and consequences of Andean-type orogenesis and the long-term evolution of fold-thrust belts, magmatic arcs, and forearc and foreland basins. - Evaluates the history of Andean mountain building over the past 300 million years - Integrates recent studies and new perspectives on the complementary records of deformation, magmatism, and sedimentary basin evolution and their interactions in time and space - Provides insight into the development of the northern, central, and southern Andes, which have typically been considered in isolation

The book focuses on geological history as the critical factor in determining the present biodiversity and landscapes of Amazonia. The different driving mechanisms for landscape evolution are explored by reviewing the history of the Amazonian Craton, the associated sedimentary basins, and the role of mountain uplift and climate change. This book provdes an insight into the Meso- and Cenozoic record of Amazonia that was characterized by fluvial and long-lived lake systems and a highly diverse flora and fauna. This fauna includes giants such as the ca. 12 m long caiman Purussaurus, but also a varied fish fauna and fragile molluscs, whilst fossil pollen and spores form relics of ancestral swamps and rainforests. Finally, a review the molecular datasets of the modern Amazonian rainforest and aquatic ecosystem, discussing the possible relations between the origin of Amazonian species diversity and the palaeogeographic, palaeoclimatic and palaeoenvironmental evolution of northern South America. The multidisciplinary approach in evaluating the history of Amazonia has resulted in a comprehensive volume that provides novel insights into the evolution of this region.
