Field Guide Travels the Backbone of the Americas

Boulder, CO, USA – With over 150 maps, diagrams, photographs, and satellite images, this new field guide from The Geological Society of America truly illustrates the Andes of Argentina and Chile on a detailed and intimate level. The five geologic field trips in this volume journey from southern Patagonia, through three regions in the south-central Andes, and on to the Puna plateau. Designed for use in the office or the field, this book also includes up-to-date overviews with references.

The geologic field guides in this volume were written for the five field trips accompanying the 3-7 April 2006 Backbone of the Americas conference in Mendoza, Argentina, co-convened by the Geological Society of America and the Asociacion Geologica Argentina, in association with the Sociedad Geologica de Chile. Volume editors Suzanne Mahlburg Kay of Cornell University and Victor A Ramos of the University of Buenos Aires chaired the meeting, which was organized around three processes influential in the evolution of the western margin and cordilleras of the Americas: ridge collision, shallowing and steepening subduction zones, and plateau and orogenic uplift. The first field trip, to southern Patagonia, highlights the ridge-trench collision theme; the next three, to different regions of the south-central Andes, examine temporal and spatial issues related to shallowing subduction; and the final trip to the central Andean Puna plateau highlights plateau uplift in the context of steepening subduction and lithospheric delamination.

Individual copies of the volume may be purchased through the Geological Society of America online store or by contacting GSA Sales and Service, .
