Purchase Memoir 204, Backbone of the Americas: Shallow Subduction, Plateau Uplift, and Ridge and Terrane Collision, and get Field Guide 13, Field Trip Guides to the Backbone of the Americas in the Southern and Central Andes: Ridge Collision, Shallow Subduction, and Plateau Uplift, for only $10 more.

Memoir 204: Papers in this volume were selected from those presented at the 2006 Backbone of the Americas Meeting, sponsored jointly by multiple North and South American geological societies in Mendoza, Argentina. Following two summary chapters on the overall anatomy and evolution of North and South American segments of the orogenic system, this volume includes ten seminal chapters dealing with salient aspects of the key geodynamic processes that have accompanied Cordilleran geotectonic evolution: forearc terrane accretion, arc magmatism, shallow subduction, and backarc intracontinental deformation.

Field Guide 13: The geologic field guides in this volume to the Andes of Argentina and Chile were written for the five field trips accompanying the 2006 Backbone of the Americas conference (see above). The meeting 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. Designed for use in the office or the field, the field guides are to regions that highlight these themes and present up-to-date overviews with references.
