Geologic mapping, facies analysis, sedimentary petrography, and detrital zircon analyses of undivided eastern Uinta Mountain Group stratigraphy are presented to better understand the depositional environments and tectonic setting of the Uinta Mountain Group basin. Subdivided units have been modified and correlated from previous work and include the Red Pine Shale, Hades Pass, Crouse Canyon, Outlaw Trail, and Diamond Breaks formations. Three lower-order maximum flooding surfaces associated with the lower Outlaw Trail formation, lower Hades Pass formation, and Red Pine Shale are interpreted. The relative magnitude of each lower-order transgression increases up section along with increasing diversity of palynomorph assemblages found in organic shale intervals. Six facies associations exist within the section and are interpreted as braided fluvial conglomerate, braided fluvial sandstone and conglomerate, braided fluvial sandstone, low-energy braided fluvial sandstone, mudflat, and offshore depositional environments. Both marine and non-marine interpretations are plausible for mudflat and offshore environments; however, previous interpretations of correlative Red Pine Shale exposures suggest a marine environment. The coarsest fluvial environments are restricted to the northern half of the study area and likely coincide with proximity to a tectonically-active northern basin margin. Paleocurrent analysis and the restriction of some subaqueous deposits to the north show northward-dipping depositional slopes, which suggest a tectonic control. Provenance work suggests three general sediment sources existed: an eastern source where ~1.1 Ga and lesser ~1.4 Ga detritus dominate, an east-northeastern source where ~1.8 Ga detritus dominate, and a north-northeastern arkosic source where ~2.7 Ga detritus dominate. Results suggest that during lower-order lowstands, sediments derived from eastern sources dominate. Higher concentrations of ~1.8 Ga and ~2.7 Ga detritus is likely coincident with proximity to the northern basin margin. During lower-order highstands, eastern or northern sources may dominate; northern sources appear more prominently within the Outlaw Trail formation, while eastern sources appear more prominently within the Red Pine Shale. Reasons for this may be linked to the magnitude of the transgressive interval sampled. These relationships, in conjunction with observations of previous studies, suggest the eastern Uinta Mountain Group was deposited in a half-graben style rift, a strike-slip basin, or some combination of the two.

The Windermere turbidite system, exposed in the southern Canadian Cordillera, east-central British Columbia, is a continental scale, passive margin, submarine fan system, part of which is well exposed in the Castle Creek study area. Here millimetre- to decametre-scale sedimentological and stratigraphic observations identified five facies in interchannel strata: very thin- to medium-bedded turbidite (F1), thick-bedded turbidite (F2) coarse-tail graded structureless sandstone (F3), mudstone clast breccia (F4) and carbonaceous mudstone (F5) and four architectural elements: channel (AE1), distal levee (AE2), overbank splays (AE3) and crevasse splays (AE4). These elements are assembled into a predictive depositional model that describes the initiation and evolution of sandy splay elements developed in distal levee strata of deep-marine slope channels. These data can be used in hydrocarbon exploration to identify and differentiate splay deposits in core and on seismic, and thereby improve the accuracy of subsurface reservoir models.

An expansive panel of well exposed (periglacial) strata of the Upper Kaza Group permitted a detailed study of the stratal architecture of proximal basin floor deposits in the Neoproterozoic Windermere turbidite system. Detailed stratigraphic and petrographic analyses identified six lithofacies: poorly-sorted, clast-rich mudstone (F1), thin-bedded siltstone and mudstone (F2), thick-bedded, massive sandstone (F3), medium-scale, cross-stratified sandstone (F4), mudstone-clast breccia (F5), and medium-bedded turbidites (F6). The spatial distribution of these facies identify five architectural elements: heterolithic feeder channel deposits (FA1), thin-bedded intralobe turbidites (FA2), terminal splay deposits (FA3), distributary channel deposits (FA4), and isolated scours (FA5). FA 1-4 are genetically related and form the basic building blocks of large-scale basin floor depositional lobes. FA 5, which is isolated to the stratigraphic top of the study area, is interpreted to have formed in a base-of-slope setting, and its superposition on FA 1-4 suggests the long-term progradation of the Windermere turbidite system.

The Red Pine Shale (RPS; ~1120m), uppermost formation of the Neoproterozoic Uinta Mountain Group, Utah, is an organic-rich sedimentary succession that represents marine deltaic systems delivering mature sediment from the east and immature sediment from the north. Multiple data sets suggest regional climate and sea-level changes associated with changing organic carbon burial rates. Six facies identified represent wave-, tidal-, and river-influenced parts of the distal prodelta to delta front. The shale facies is interpreted as distal prodeltaic deposition in a marine environment. The concretion facies is interpreted as prodeltaic deposition to distal prodelta. The shale-sandstone facies represents suspension settling with dilute density currents in a proximal prodelta to delta front environment. The slump fold facies was deposited on the proximal prodelta or delta front. The sandstone facies represents deposition on the delta front and shows marine- and river- influences. The pebbly sandstone facies is representative of a delta front environment. C-isotope values from this shale range from -29.46 / to -16.91 / PDB and TOC from 0.04% to 5.91%. Combined H/C, TOC, and local-regional isotopic correlations suggest that these values are representative of C-isotope composition of Neoproterozoic seawater. The composite C-isotope curve for the RPS is less negative values near the base, followed by a long decline to a thick interval of homogeneous lower values. Petrographic analyses reveal immature arkosic sandstone and mature quartz arenite populations. Detrital zircon data show an Archean population from the Wyoming Craton to the north and a mixed Proterozoic/Archean population from the east-southeast. Measured sections show north to south delta progradation with a proximal source to the north and a mature sediment source to the east. The composite section shows one low-order regressive cycle and ~11 high-order cycles. There is a relationship between C-isotope values, shale geochemistry, and lithostratigraphy. Less negative C-isotope values correspond with increased kaolinite and facies indicating higher sea-level. These relationships are seen in the correlative Chuar Group, Arizona, and a similar model is suggested for their origin: humid climate, high organic carbon burial rates, and high sea-level. This paper meets the requirements to revise the RPS as a formalized unit in accordance with the Stratigraphic Code guidelines.
