Fission-track ages of apatite in the Wasatch Mountains, Utah: An uplift study

Apatite fission-track ages from basement rocks in the Wasatch Mountains between Ogden and Bountiful, Utah, range from 5 m.y. near the Wasatch fault along the west margin of the mountains to 94 m.y. on the crest of the range and show a correlation with altitude within individual fault blocks. Analysis of these ages yields an uplift rate of 0.4 mm/yr for the last 10 m.y. for the fault blocks having the most sustained rapid uplift. A variety of intermediate ages of apatite from the crest of the range and at lower altitudes is interpreted as representing fault blocks with rocks having mixed ages due to various degrees of tilting and varying but lesser amounts of uplift.

Mineral resource potential map of the Stansbury Roadless Area, Tooele County, Utah

The U.S. Bureau of Mines and the U.S. Geological Survey have conducted a survey to determine the mineral resource potential of the eastern part (D4757) of the Stansbury Roadless Area, Tooele County, Utah. The results of this survey indicate that a low to moderate potential for copper, lead, and silver mineralization exists in part of area D4757. The balance of area D4757 is considered to have a low potential for metallic mineralization. The oil and gas potential is not known and cannot be assessed without a program of geophysical exploration and exploratory drilling. Limestone and dolomite are exposed over a large part of the roadless area, forming a major industrial mineral resource, but an extensive sampling and testing program is needed to determine the degree of purity of the rocks and, hence, the value of the resource. There are no known geothermal resources within the study area.
