Andean Tectonics addresses the geological evolution of the Andes Mountains, the prime global example of subduction-related mountain building. The Andes forms one of the most extensive mountain 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 250 million years (the Mesozoic and Cenozoic eras)
- Integrates recent results and provides 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

Dr. Horton is the Alexander Deussen Professor of Energy Resources at The University of Texas at Austin and has a joint appointment with the Department of Geological Sciences and Institute for Geophysics in the Jackson School of Geosciences. He received his Ph.D. from the University of Arizona in 1998. His research addresses tectonics of sedimentary basins, evolution of orogenic systems, sediment provenance, and nonmarine depositional processes.
Andrés Folguera is a Research Scientist (Investigador Principal) and Professor with CONICET (National Scientific and Technical Research Council) and the Universidad de Buenos Aires, Facultad de Ciencis Exactas y Naturales, where he has an appointment with the Departamento de Ciencias Geológicas, Instituto de Estudios Andinos, Laboratorio de Geodinámica. His research focuses on the tectonics, structure, magmatism, geomorphology and neotectonics of the central and southern Andes, particularly for the last 100 million years of their evolution.
