Pre-Mesozoic palinspastic reconstruction of the eastern Great Basin (western United States)
Levy M and Christie-Blick N. 1989. Pre-Mesozoic palinspastic reconstruction of the eastern Great Basin (western United States). Science. 245(4925):1454-1462
The Great Basin of the western United States has proven important for studies of Proterozoic and Paleozoic geology and has been central to the development of ideas about the mechanics of crustal shortening and extension. This report creates a new reconstruction for rocks of middle Proterozoic to Early Cambrian age based on evidence that total shortening by generally east-vergent thrusts and folds was at least 104 to 135 kilometers and that the Great Basin as a whole accommodated ~250 kilometers of extension in the direction 287 degrees plus/minus 12 degrees between the Colorado Plateau and the Sierra Nevada.
