Description: This dataset represents the geology of the Deep Creek Mountains Wilderness Study Area at 1:50,000 scale.This GIS dataset is reproduced from “Rodgers, D.W., 1989, Geologic map of the Deep Creek Mountains Wilderness Study Area, Tooele and Juab Counties, Utah: U.S. Geological Survey Miscellaneous Field Studies Map MF-2099, 1 plate, scale 1:50,000.” The map covers approximately six 7.5' quadrangles in west-central Utah. The GIS dataset was completed by Joshua Meibos, student at Brigham Young University, and final GIS review and preparation for public release were completed by Zach Anderson, Martha L. Jensen, and Rosemary Fasselin, GIS Analysts with the Utah Geological Survey (UGS).The UGS appreciates the volunteered time and effort of the student Joshua Meibos who produced the GIS data for this project in 2016 under the guidance of Brigham Young University professor Eric Christiansen.Late Proterozoic and Paleozoic rocks of the Deep Creek Range form a thick sequence that accumulated in fluvial to shallow marine environments on a subsiding continental shelf. In the Late Cretaceous, possibly earlier, deep seated Late Proterozoic strata were regionally metamorphosed and a cleavage formed in mudstone, most likely accommodating east-directed translation of the entire stratigraphic sequence. Thrusting along the Birch Canyon fault and Rocky Springs thrust may have occurred at this time. The geometry and timing of these structures suggest they formed in the hinterland of the Sevier fold and thrust belt, coeval with east-directed thrusting in central Utah (Armstrong, 1968; Lawton, 1985). Between 73 Ma and 39 Ma, Late Proterozoic to Mississippian strata in the southern Deep Creek Range were folded into the Water Canyon anticline, which may also reflect east-west shortening in the hinterland of the Sevier fold and thrust belt. After emplacement of the 39 Ma Ibapah stock, possibly in the early Miocene, the Reilly Canyon normal fault extended to a depth of about 9 miles and accommodated differential uplift and east-west extension of the Deep Creek Range. Due to fault rotation, the entire range was tilted to the west during uplift. Finally, late Tertiary and Quaternary uplift along normal faults produced the modern Deep Creek Range. This fault geometry and timing is typical of the Basin and Range Province.This dataset was produced as part of a UGS multi-decade effort to provide statewide GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic issues such as attributing faults. We changed some geologic line symbols to better match the UGS 2020 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1989 and does not meet all modern cartographic, spatial control, or geologic standards.The GeoTiff file utilizes a basemap from the USGS US Topo Clifton, Goshute, Goshute Canyon, Ibapah, Ibapah Peak, Indian Farm Creek, Partoun, and Trout Creek 7.5' Quadrangles (2017).Not all features on the original map precisely match options in the 2020 UGS geologic map schema as noted below. Line attributes and symbology were selected from current (2020) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match.FaultThese lines are now depicted as "Fault, unknown, well located," "Fault, unknown, approximately located," "Fault, unknown, approximately located, queried," "Fault, unknown, concealed," or "Fault, unknown, concealed, queried." Normal FaultThese lines are now depicted as "Fault, normal, well located," "Fault, normal, approximately located," or "Fault, normal, concealed." Thrust FaultThese lines are now depicted as "Fault, thrust, well located" or "Fault, thrust, approximately located."Unknown FaultThe fault in Deep Creek Valley was attributed as a queried unknown fault.Reilly Canyon fault was made an unknown fault. Units – Descriptions/Names/AgesThe map is not modified from original source map even in locations where newer interpretations may exist.Wilderness Study Area BoundaryWe vectorized the boundary on the original geologic map, which was drawn on a stitched-together topographic basemap compilation. The geospatial accuracy of the depicted boundary is not known to the UGS. The boundary has subsequently been changed, as indicated by the following link:https://www.blm.gov/sites/blm.gov/files/documents/files/BLMUtahDeepCreekMountainsWSA_0.pdf
