Geologic and Geophysical Maps of the Newfoundland Mountains and Part of the Adjacent Wells 30' x 60' Quadrangles, Box Elder County, Utah (MP-173dm)

1:62,500 and 1:50,000 Geologic Maps

The Newfoundland Mountains 30′ x 60′ quadrangle encompasses broad expanses of the Great Salt Lake Desert as well as several picturesque mountain ranges, including the Newfoundland Mountains and the Pilot Range. The map area is located within the Basin and Range Province and exhibits fault-bounded mountains separated by broad valleys. Neoproterozoic to Quaternary rocks of metamorphic, sedimentary, and igneous origin crop out in the mountains. The area records a complex tectonic history that includes Mesozoic thrusting, extension, and plutonism, as well as Cenozoic extension, plutonism, and volcanism. Basins are primarily mantled by alluvial fans and playas that are covered in some places by extensive thin deposits from Pleistocene Lake Bonneville. New geophysical studies provided key data for improved interpretation of the subsurface geology within the basins.
