Index of faults of Cretaceous and Cenozoic age in the eastern United States Index of faults of Cretaceous and Cenozoic age in the eastern United States
The information in this report was collected between 1974 and 1982 as part of the Reactor Hazards Program of the U.S. Geological Survey (USGS). This program was initiated to delineate and assess geologic hazards that could be particularly detrimental to major constructions, especially nuclear reactors. Faults are of principal interest to the program because earthquakes associated with...
Isopach and structure contour maps of the Burro Canyon(?) Formation in the Chama-El Vado Area, Chama Basin, New Mexico Isopach and structure contour maps of the Burro Canyon(?) Formation in the Chama-El Vado Area, Chama Basin, New Mexico
In the Chama Basin a wequence of conglomerate, sandstone, and red, gray-green, and pale-purple mudstone occurs stratigraphically between the Upper Jurassic Morrison Formation and Upper Cretaceous Dakota Sandstone. This stratigraphic interval has been called the Burro Canyon Formation by several workers (Craig and others, 1959; Smith and others, 1961; Saucier, 1974). Although similarities...
