GSA Special Paper 442.

Displaced or tectonostratigraphic terranes comprise a huge portion of real estate in the North American Cordillera. Terranes are discrete, fault-bound blocks of regional extent, with rocks and fossils that differ to a great extent from those of adjacent blocks. The allochthonous nature of most terranes, relative to adjacent craton, is well established. When mapped, they resemble a collage of mixed rock types, tectonic styles, metamorphism, and volcanic origins—each part resembling the pieces of a puzzle. Terrane studies remain integral to understanding the geological evolution of western North America. Since the initiation of the concept summarized in 1979 by the late David Jones L. Jones, the significance of fossils and stratigraphy has been key to solving the puzzle. Chapters of this book written by experts in their field, provide a sense of the diversity of approaches in paleontology and stratigraphy. Contributions span geologic time from the Precambrian (Vendian) to Cretaceous and address over 20 Cordilleran terranes.
