New GSA Special Paper
Boulder, CO, USA - The broadly accepted hypothesis for the development of the segmented Cordilleran orogen above a long-lived eastwardly dipping subduction zone is at odds with many critical observations. In this new Special Paper from The Geological Society of America, Robert S. Hildebrand of the University of California-Davis explores an alternative collisional model. This well-illustrated book, which includes a pull-out map, builds upon Hildebrand's earlier work, published as GSA Special Paper 457 (2009).
Starting with an overview of Cordilleran exotic and suspect terranes, Hildebrand builds upon his model for the Mesozoic collision of the exotic Rubian ribbon continent with the western margin of North America. He integrates the disparate fragments into a dynamic model involving arc magmatism, arc-continent collision, slab failure magmatism, and meridional migration. While the main focus is on the offshore assembly of the Rubian ribbon continent, Hildebrand explores its interactions with North America during the Sevier and Laramide events and concludes that North America was the lower plate in both.
Hildebrand notes that this new volume "will be of great interest to the general geological community, including advanced students, as it presents new ideas on the Mesozoic assembly of California and provides the first overview of the North American Cordillera since GSA's Decade of North American Geology volumes some 20 years ago."
