Field Guide to Plutons, Volcanoes, Faults, Reefs, Dinosaurs, and Possible Glaciation in Selected Areas of Arizona, California, and Nevada by Ernest M. Duebendorfer,Eugene Irwin Smith Pdf

Papers from the 2008 combined Cordilleran and Rocky Mountain Sections meeting of the Geological Society of America provide background information and road logs for 11 field trips in Nevada, Arizona, and California. Field trips span the geological record from the Ediacaaran (late Neoproterrozoic) to the Holocene. The field trips highlight features of tectonics, paleontology, volcanism, and glaciation. B&w and color photos and maps are included. There is no subject index. Duebendorfer is affiliated with Northern Arizona University. Smith is affiliated with the University of Nevada-Las Vegas.

Peninsular Ranges Batholith, Baja and Southern California by Douglas M. Morton,Fred K. Miller Pdf

"This book includes petrology, geochronology, and regional aspects of individual plutons, as well as evolution of the Peninsular Ranges batholith. Several chapters deal with geophysical, chemical, and isotopic based interpretations of the genesis and evolution of the batholith. An accompanying DVD contains detailed colored maps and chemical, isotopic, mineralogic, and physical properties data"--Provided by publisher.

The Tectonic Setting and Origin of Cretaceous Batholiths within the North American Cordillera by Robert S. Hildebrand,Joseph B. Whalen Pdf

In this Special Paper, Hildebrand and Whalen present a big-picture, paradigm-busting synthesis that examines the tectonic setting, temporal relations, and geochemistry of many plutons within Cretaceous batholithic terranes of the North American Cordillera. In addition to their compelling tectonic synthesis, they argue that most of the batholiths are not products of arc magmatism as commonly believed, but instead were formed by slab failure during and after collision. They show that slab window and Precambrian TTG suites share many geochemical similarities with Cretaceous slab failure rocks. Geochemical and isotopic data indicate that the slab failure magmas were derived dominantly from the mantle and thus have been one of the largest contributors to growth of continental crust. The authors also note that slab failure plutons emplaced into the epizone are commonly associated with Cu-Au porphyries, as well as Li-Cs-Ta pegmatites.

Introduction to the Geology of Southern California and Its Native Plants by Clarence A. Hall Jr. Pdf

With its active fault systems, complex landforms, and myriad natural habitats, southern California boasts a rich and dynamic geologic environment. This abundantly illustrated volume at last provides an up-to-date, authoritative, and accessible resource for students and general readers interested in southern California's geology and native plants. Covering an extensive area, north from San Diego to Yosemite in the Sierra Nevada and east to the Mojave and Colorado deserts, its unique, comprehensive approach brings together for the first time the basic principles of geology, the story of plate tectonics, in-depth discussion of the geology of many specific locales within the region, and information on identifying southern California's native plants.

Mesozoic Assembly of the North American Cordillera by Robert S. Hildebrand Pdf

"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.

Did Westward Subduction Cause Cretaceous-Tertiary Orogeny in the North American Cordillera? by Robert S. Hildebrand Pdf

Within the Sonora segment to the south, break-off magmatism was also prevalent. Both the Canadian and Sonoran segments have abundant porphyry copper mineralization temporally and spatially associated with the break-off magmas, which suggests a genetic link between slab failure and porphyry copper mineralization. By 53 Ma, eastwardly dipping subduction of Pacific Ocean crust was generating arc magmatism on the amalgamated Cordilleran collision zone in both the Canadian and Sonoran segments. Oceanic schists, such as the Orocopia-Pelona-Rand, were formed in the ocean basin west of Rubia and accreted during initiation of the new easterly dipping subduction zone. A major transform fault, called the Phoenix fault, connects the Sevier fold-thrust belt at the California-Nevada border with that in eastern Mexico and separates the Great Basin and Sonoran segments. It juxtaposes the Sierra-Mojave-Sonora block alongside the Transition Zone of the Colorado Plateau. Cordilleran events affected the subsequent development of western North America. For example, the structural Basin and Range Province appears to coincide with the region where exotic allochthons sit atop North American crust in both the Great Basin and Sonoran segments. Also, within the triangular Columbia embayment, large segments of Rubia appear to have escaped laterally during the Cordilleran orogeny to create a lithospheric "hole" that was later filled by basalt of the Columbia River and Modoc plateaux.
