Andean Tectonics

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 yearsIntegrates recent studies and new perspectives on the complementary records of deformation, magmatism, and sedimentary basin evolution and their interactions in time and spaceProvides insight into the development of the northern, central, and southern Andes, which have typically been considered in isolation
