Geology of the North American Air Defense Combat Operations Center, Cheyenne Mountain and Peripheral Area, Near Colorado Springs, El Paso County, Colorado

摘要

The NORAD Project, Combat Operations Center, is in Cheyenne Mountain, consisting largely of highly fractured granite. The fracturing is genetically related to the Ute Pass fault, the major boundary along the eastern side of a large granitic block, uplifted vertically more than 20,000' and partially thrust over a 7000-8000' thickness of sediments. The investigation of the area was undertaken to: (1) establish the distribution of major geologic features which could have an important bearing on interpretation of deep crustal resistivity data, and (2) to locate a drill hole for use in deep strata communication testing.
