Synapsid Burrows in the Lower Jurassic Navajo Sandstone, Utah
… below interdune deposits of the Lower Jurassic Navajo Sandstone near Moab, Utah are interpreted as synapsid burrows based on similar morphologies to fossil and extant synapsid burrows. Two types of burrows are distinguished by their size. Type I burrows are large diameter and comprise complex, …

Soft-sediment Deformation and Dune Collapse in the Navajo Sandstone
… of Zion National Park follows an outcrop of Navajo Sandstone, which displays a uniquely well-exposed assemblage of features associated with failure of the lee face of a large eolian dune, and run-out over an expanse of interdune sediments downwind of that bedform. Exposed features include …

Reservoir Characterization and Outcrop Analogs to the Navajo Sandstone in the Central Utah Thrust Belt Exploration Play
… reservoir heterogeneity of the Early Jurassic Navajo Sandstone in the Justensen Flat/Devils Canyon area of the San Rafael Swell, Utah. These outcrops are located approximately 60 kilometers (45 mi) east of the recently discovered Covenant oil field which is located in the central Utah thrust …

Fault formation in porous sedimentary rocks at high strain rates
… investigation of faults mapped within the porous Navajo Sandstone at the Upheaval Dome impact structure in Canyonlands National Park, southeast Utah, where high strain rate conditions are known to have occurred. We found no evidence for DBDZ formation along the fault planes at Upheaval Dome. …

Piecing Together the Triassic/Jurassic Stratigraphy Along the South Flank of the Uinta Mountains, Northeast Utah: A Stratigraphic Analysis of the Bell Springs Member of the Nugget Sandstone
… set of formation names is used. The Nugget Sandstone or Glen Canyon Sandstone of the eastern Uinta Mountains overlies the Upper Triassic Popo Agie or Chinle Formation. The nature of the contact between these two formations is unclear both in stratigraphic location and conformability. The …

The kanarra fold-thrust system -- The leading edge of the sevier fold-thrust belt, southwest Utah
… as a distinctive cataclasite zone in the Navajo Sandstone, which is thrust over the Jurassic Carmel and younger Cretaceous strata. Traceable from Kanarraville to Parowan Gap, this thrust is the leading edge of the Sevier fold-thrust belt in southwest Utah. Stratigraphic relationships …

Geologic Map and Structural Analysis of the Twin Rocks 7.5 Minute Quadrangle, Wayne County, Utah
… and Moenkopi Formations and the Jurassic Page Sandstone, a stratigraphic unit herein separated from the Navajo Sandstone. Terraces associated with Sulfur Creek record the central pathway of ancient streams rather than the lateral extent of the floodplain. Volcanic boulder-rich terrace deposits …

Geochemical records in travertine veins at the Green River CO2 seeps (Utah)
… reactive transport model for flow in the Navajo sandstone. This model is calibrated using spring fluid samples, and applied to interpret vein samples. Trends in δ234Ui are more easily interpreted spatially, due to increased residence times inferred from α-recoil inputs. This is counter to …

Fluid-rock interactions in a carbon storage site analogue, Green River, Utah
… evolution of groundwater from the Jurassic Navajo Sandstone, part of a leaking natural accumulation of CO2 at Green River, Utah, in the Colorado Plateau, USA, to place constraints on the rates and potential controlling mechanisms of the mineral-fluid reactions,under elevated CO2 pressures, …
