... derived from tuff cones (Pavant Butte and Tabernacle Hill) that erupted into Lake Bonneville in what is now the Black Rock Desert of south-central Utah. Near Kanosh, Utah, the Pavant Butte ash is interbedded with barrier-beach lagoon marl that is slightly less than 16,000 yr old. Five radiocarbon dates...

Thus, due to the lack of good stratigraphic control, the palinspastic restorations by Sharp (1984) , which Von Tish et al (1985) used as evidence to prove (although we are not sure...

Sonic and density logs, as well as some dipmeter and sample logs for these wells, are available through the Utah Division of Oil, Gas, and Mining Web site. The Cominco well...

It referred to the general pattern of volcanism and age distribution of flows and cones in the Pavant Butte and Deseret volcanic fields, which belong to a trend of basaltic volcanism extending south into the Black Rock Desert ( Gilbert, 1890 ; Condie and Barsky, 1972...

...Peter G. DeCelles; James C. Coogan Abstract The Canyon Range, Pavant, Paxton, and Gunnison thrust systems in central Utah form the Sevier fold-and-thrust belt in its type area. The Canyon Range thrust carries an ∼12-km-thick succession of Neoproterozoic through Triassic sedimentary rocks...

... consisted of a frontal zone, where major thrusts with 50–100 km of displacement breached the surface (e.g., Canyon Range and Pavant thrusts; DeCelles and Coogan, 2006 ), and a hinterland zone, characterized by more distributed fold-thrust systems, with three or more thrust belts (central Nevada, Butte...

The upper part may be middle Devonian based on the Athyris circula fauna ( Johnson, 1962b ) found in the sandy member in central Nevada.

In Juab Valley, a half graben containing 10°W- to 30°W-dipping Paleogene–Neogene rocks formed from 3 km of down-to-the-E offset on a normal fault that soles into the roof thrust of the Pavant duplex. Further west in Juab Valley, the Pavant thrust was reactivated...
