Abstract:
"In this well-illustrated book, Hildebrand expands upon his model for the development of the North American Cordillera detailed in Special paper 457. Starting with an overview of cordilleran geology he goes on to provide an in depth look at how the Rubian ribbon continent was assembled. He integrates the complex geology of the cordillera into an actualistic model involving arc magmatism, arc-continent collision, slab failure magmatism, and transcurrent motion in both Rubia and the western North American margin. While much of the focus is on the 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"--Provided by publisher.
