Preliminary Geologic Map of Sequoia and Kings Canyon National Parks, California
Author: James Gregory MoorePublisher:
ISBN:
Category : Geology
Languages : en
Pages : 22
Book Description
"This report describes and provides background for the accompanying preliminary geologic map of Sequoia and Kings Canyon National Parks compiled on the special topographic map of the parks at a scale of 1:125,000. This geologic map of the parks is one-half the scale of the 12 published geological quadrangle maps (scale 1:62,500) that cover more khan half of the parks area. Therefore it was necessary to simplify cartographic detail and to portray a minimum number of lithologic units. .... This open file map, and the explanatory text, is intended as a general assessment of the regional geology of the parks area, as a resource for planning further geologic research in the parks, and as a guide for the park interpretive staff in the geologic framework and geologic history of the parks. It is also an initial step in the preparation of a final map to accompany a popularized report on the geology of the parks."--Page 2.

The Mountains That Remade America
Author: Craig H. JonesPublisher: Univ of California Press
ISBN: 0520325508
Category : History
Languages : en
Pages : 358
Book Description
From ski towns to national parks, fresh fruit to environmental lawsuits, the Sierra Nevada has changed the way Americans live. Whether and where there was gold to be mined redefined land, mineral, and water laws. Where rain falls (and where it doesn't) determines whose fruit grows on trees and whose appears on slot machines. All this emerges from the geology of the range and how it changed history, and in so doing, changed the country. The Mountains That Remade America combines geology with history to show how the particular forces and conditions that created the Sierra Nevada have effected broad outcomes and influenced daily life in the United States in the past and how they continue to do so today. Drawing connections between events in historical geology and contemporary society, Craig H. Jones makes geological science accessible and shows the vast impact this mountain range has had on the American West.
Mesozoic Assembly of the North American Cordillera
Author: Robert S. HildebrandPublisher: Geological Society of America
ISBN: 0813724953
Category : Science
Languages : en
Pages : 182
Book Description
"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.

The Tectonic Setting and Origin of Cretaceous Batholiths within the North American Cordillera
Author: Robert S. HildebrandPublisher: Geological Society of America
ISBN: 0813725321
Category : Nature
Languages : en
Pages : 123
Book Description
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.
