Cenozoic Stratigraphy of Southwestern High Plateaus of Utah

“…Such significant results as have been achieved were largely the accomplishments of three men: Callaghan (1938Callaghan ( , 1939Callaghan ( , 1973Callaghan and Parker, 1961a, 1961b, 1962a, 1962bWillard and Callaghan, 1962), who mapped several quadrangles centered around Marysvale, Utah; Kerr (1963Kerr ( , 1968Kerr and others, 1957), who with his students refined and expanded parts of Callaghan's work in the Marysvale uranium district; and Gregory (1944Gregory ( , 1945Gregory ( , 1949Gregory ( , 1950Gregory ( , 1951, who dealt with parts of the Paunsaugunt, Sevier, and Markagunt Plateaus.…”

“…Although he was puzzled by the origin of these rocks, which he termed "tufas," he recognized that they were generally the oldest eruptive rocks. In the Marysvale district, Callaghan and his associates (Callaghan, 1939;Callaghan and Parker, 1961a, 1961b, 1962a, 1962bWillard and Callaghan, 1962) included Dutton's "tufas" in their Bullion Canyon Volcanics of Miocene(?) age.…”

“…The area described is outlined on the generalized geologic map of Utah ( Figure 2) and lies within lat. 38°18 1 30 11 and 38°43 1 02 11 N. and long. 112°00 1 00 11 and 112°35 1 00 11 W., which includes portions of Sevier, Piute, and Beaver Counties.…”

“…Laboratory analysis t as we 11 as compilation and verification of field and laboratory data, continued throughout the sampling period. The final field and laboratory data base used to prepare the statistical and areal distribution of uranium and other related variables for this report was completed in April 1980.…”

“…Eaststriking faults occur in the mineral belt. Callaghan and Parker (1962), Kennedy (1963), andOallaghan (1973) noted that the Tushar Mountains probably occupy part of an east-trending arch that is bounded on its northern side (in the major east-trending valley of Clear Creek near the northern edge of the mineral belt) by a parallel downwarp. The arch occurs in the same area where an east-trending highland of probable Late Cretaceous or early Tertiary age extended both east and west of the Tushar Mountains (Butler and others, 1920;Callaghan, 1973;Anderson and Rowley, 1975).…”
