This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Late Cretaceous upper Sego Member of the Mancos Shale exposed in the Book Cliffs of east-central Utah is a 30 m thick sandstone wedge that overlies the Anchor Mine Tongue of the Mancos Shale and underlies coastal plain deposits of the Neslen Formation. Although this sandstone has been interpreted to be comprised of transgressive valley fills, recent detailed facies architecture studies of the underlying lower Sego Sandstone suggest these deposits may instead be regressive deposits of tide-influenced deltas. This study maps facies associations, the geometry of lithic bodies, and key stratigraphic surfaces in order to define the architecture of a 12 km long cross section of the upper Sego Sandstone. This broadly depositional dip-oriented cross section exposes a vertical stack of three sandy intervals, truncated by a high-relief erosion surface, and capped by a shell rich lag. Sandy intervals are interpreted be an assemblage of forward stepping successions of tide-influenced delta lobes. Interval 1, dominantly highly marine bioturbated sandstones which thin landward over kilometers, is cut locally by an erosion surface overlain by tidal bed sets. It is capped by a localized transgressive shell lag and then a thin continuous marine shale. Intervals 2 and 3 are composed of stacked tidal bar deposits that successively coarsen upward and thicken basinward. Interval 2 is overlain by thin marine shales, whereas interval 3 is capped by a pronounced oyster shell lag ravinement surface. A high-relief erosion surface that extends from the top of the upper Sego sandstone down into the Anchor Mine Tongue Shale, is overlain by coarser-grained amalgamated fluvial channel deposits and is interpreted to be a incised valley fill. Erosion surfaces at the base of sandy intervals, thicken and decrease in marine bioturbation within successive intervals, and the valley cut into this succession reflects episodic forced regression of a deltaic shoreline.

Griffin and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Incised valley systems are important because they contain significant hydrocarbon reserves, provide clues into the geologic history of a region, and are crucial for sequence stratigraphic interpretations. The fluvial/deltaic Notom Delta component of the Turonian (Late Cretaceous) Ferron Sandstone Member of the Mancos Shale outcrops in south-central Utah providing an excellent opportunity to study a terrace deposit in both strike and dip orientations of a compound incised valley system. Using traditional field methods conducted during the summer of 2012, detailed cross sections and bedding diagrams were created that show a terrace deposit (Valley 3) that has been previously undescribed. This terrace deposit formed in response to multiple sea-level fluctuations. The presence of a tidal signature along with the proximity of the incised valley system to the coastal plain (parasequence 4) suggest the presence of a Coastal Plain Valley System. Fill from this incised valley deposit would also fall within the shorter, less preserved deposits of the segment 2 middle incised valley deposits of the idealized longitudinal incised valley model. Paleocurrent and bar accretion measurements taken from within individual channel belts of the incised valley generally showed accretion occurring at high angles to that of the paleocurrent direction. This suggests the fluvial style responsible for the formation of this incised valley system was meandering. Previous regional stratigraphic studies have shown that the incised valley system within the study area is a falling stage terrace deposit. This is incongruous with previous sequence stratigraphic models that early, falling stage valley fills are a result of braided rivers. Paleo-flow depths that were calculated based on cross-set thicknesses for Valley 3 indicate an average flow depth of 3.3 to 5.4 meters.

Available in PDF, EPUB and Kindle. Book excerpt: Examination of fluvial deposits of the Late Cretaceous (Turonian) Ferron Sandstone Member, within the Mancos Shale Formation, in Central Utah (along Sweetwater Wash) was done to interpret fluvial style, characterize avulsion, and better constrain controls on channel-belt geometry. Cross sections were created based on measured sections and walking out beds, and showed two highly amalgamated sheet sands (Channel-belt A&C) separated by floodplain-encased channel-belts (isolated Channel-belt group B). The extensive sheet sandstones overlie distal floodplain deposits, and were subsequently characterized as regional avulsions. The isolated channel-belts overlie more proximal lacustrine and floodplain deposits, and were characterized as local avulsions. Detailed analysis of Channel-belt C showed a laterally extensive, unconfined channel-belt, formed by rivers 2.5-4 meters deep, with average storeys of 1.8 meters and bar lengths between 150-190 meters. Consistent paleo-current directions, evidence of downstream accretion, and a confluence zone, in highly scoured sheet-like deposits, suggest the deposition of Channel-belt C by a dominantly braided river. Correlation to a previously developed sequence stratigraphic framework showed that base level is an allocyclic control on alluvial architecture, with possible glacio-eustatic cycles controlling the regional stratigraphy. Channel-belt clusters were observed within the isolated channel-belts, but were not uniform across the basin, so they were interpreted as autocyclic or random, and not related to incised valleys below. Evidence for autocyclic controls, such as substrate erodability, was documented with laterally continuous indurated coals favoring extensive channel migration and the deposition of vi sheet sands. Sandy substrates favored channel reoccupation and vertical amalgamation. Comparing my data to net-to-gross models showed that the high net-to-gross and highly amalgamated deposits of the lower Channel-belt C are mainly associated with braided rivers, whereas meandering rivers are dominant in the low net-to-gross deposits of the isolated channel-belts; thus showing some similarities to previous net-to-gross models.

This book was released on 2001 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of phase 1 and phase 2 of the Department of Energy funded project Analysis of oil- bearing Cretaceous Sandstone Hydrocarbon Reservoirs, exclusive of the Dakota Sandstone, on the Jicarilla Apache Indian Reservation, New Mexico was to define the facies of the oil producing units within the Mancos Shale and interpret the depositional environments of these facies within a sequence stratigraphic context. The focus of this report will center on (1) redefinition of the area and vertical extent of the ''Gallup sandstone'' or El Vado Sandstone Member of the Mancos Shale, (2) determination of the facies distribution within the ''Gallup sandstone'' and other oil-producing sandstones within the lower Mancos, placing these facies within the overall depositional history of the San Juan Basin, (3) application of the principals of sequence stratigraphy to the depositional units that comprise the Mancos Shale, and (4) evaluation of the structural features on the Reservation as they may control sites of oil accumulation.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is focused on analysing architectural elements to understand the formative processes in linked fluvial and deltaic depositional systems in an ancient system. A compound incised valley system (IVS) and distributary channel and crevasse delta system are documented in successively more distal positions within outcrops of the Cretaceous Ferron Notom Delta in central Utah. The compound IVS is composed of three simple IVS systems, IVS3, IVS2 and IVS1 (oldest to youngest). IVS3 consists of tidally influenced deposits that form a terrace cut into lower shoreface deposits. IVS2 consists of multi-storey fluvial deposits with minor tidally influenced fluvial deposits in the upper 10%. IVS1 consists entirely of medium-grained fluvial deposits. The composite valley fill records generally increasing fluvial-dominance and decreasing tide-influence during successive cut-and-fill episodes associated with each simple valley fill. These changes are interpreted to correlate with a longer term, stepped relative fall of sea level, punctuated by stillstands, or minor rises of sea level. A lower delta-plain distributary channel system is mapped in 3-D outcrop exposures in Parasequence 5a, Sequence 2. A main channel belt about 250 m wide narrows to 200 m downstream of the branching point. The subordinate channel belt is 80 m wide. Water discharge from the main distributary channel, upstream of the branching point, is estimated to be 85-170 m3/s. Compared to paleodischarge of trunk rivers mapped in previous studies in the Notom Delta, the branching is estimated to be a 4th order split. A crevasse delta that prograded toward the west is mapped in Parasequence 6a Sequence 2, while the regional delta prograded toward the east. The crevasse delta was protected from marine influence by a wave-dominated barrier system. The proximal delta-front facies consists of planar beds which pass upward into meter-scale low-angle cross beds, which decrease in dimensions upward and finally change to decimeter-scale cross beds. Planar-stratified sandstones are interpreted to be deposited in an inertia-dominated environment and cross-stratified sandstones are interpreted to be deposits in a friction-dominated environment. The upward decrease of cross set dimensions is mainly due to the filling of accommodation and shallowing of the water.
