About this Book
Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 130.
The Colorado Plateau is a broadly elevated region in the southern part of the Western Interior of the United States that has exceptionally fine exposures of upper Paleozoic, Mesozoic, and Cenozoic rocks. The quality of exposures is a product of regional uplift in the middle and late Tertiary that caused rapid erosion and deep canyon incision in a semi-arid to arid climate. The structure of the Plateau consists of broad basins, uplifts, and platforms locally bordered by monoclines. Although elevated in Tertiary time, the Plateau region was a distinct crustal block by the beginning of Mesozoic time when it was largely surrounded by tectonically distinct regions. Upper Paleozoic to Cenozoic strata contain the record of marine and continental sedimentologic processes complicated in varying degrees by the interplay between sea-level changes and tectonism, both within the Plateau region and in bordering regions. The field excursion will provide an opportunity to see the spectacular geologic scenery of the Colorado Plateau and to discuss the regional sedimentologic and structural history.
