Geology and ore deposits of the Monument Valley area, Apache and Navajo Counties, Arizona
In 1951 the U.S. Geological Survey undertook a program of uranium investigations in Apache and Navajo Counties, northeastern Arizona. The work had three major objectives. The first was to accumulate data basic to an understanding of the regional geology. The second was to appraise the Triassic strata as host rocks for uranium deposits, and to select areas favorable for exploration for concealed deposits. The third objective was to study the controls that influence uranium deposition and from this study, to establish guides useful in prospecting for uranium deposits.
