This dataset represents the geology of the Newfoundland Mountains and east part of the Wells Quadrangles at a 1:62,500 scale.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.This publication includes geographic information system (GIS) files in ESRI file geodatabase and shapefile formats. Also included are three PDFs: two plates (the geologic map at 1:62,500 scale and an explanation sheet) and a 26-page booklet with interpretive information and geologic unit descriptions. Specialized GIS software is required to use the GIS files. |
