Book excerpt: Deep-water depositional systems commonly show two end-member styles of stratigraphic architecture: laterally confined channelized deposits on the slope and more depositional, unconfined distributary channel-lobe deposits on the basin floor. In between, a transitional stratigraphic architecture comprising scours and short-lived, low-sinuosity channels can form. This transitional stratigraphic architecture has been most commonly recognized on the modern seafloor where the components of deep-water depositional systems can be studied in full plan-view display. Outcrops of the Permian Brushy Canyon Formation in the Delaware Basin show weakly confined channel deposits thought to be found in these transition zones. Brushy outcrops have been described as laterally migrating, sandy channel fills up to 500 m wide and 30 m thick deposited in areas of low to moderate gradient. Although outcrops provide high-resolution cross sections of the sedimentology and stacking of deep-water deposits, they lack the larger scale, three-dimensional context of seismic-reflection data and well logs used for basin-framework studies. Here, I integrate a large number of geophysical well logs (1,366) and 3D seismic-reflection data (~30 Hz dominant frequency) covering ~500 km2 in the northeastern Delaware Basin, southeastern New Mexico. I created a three-dimensional log-based stratigraphic model of the Brushy Canyon Formation and characterized the depositional architecture within the West Hobbs deep-water depositional system on the basin floor. Generally, the proximal Brushy Canyon Formation consists of lenticular sand bodies interstratified with sheet-like units, and the gamma-ray logs show local blocky, isolated relatively coarse-grained deposits bounded by thicker relatively fine-grained deposits. Downstream, there is a transition to more continuous, sheet-like deposits. I used a spectral decomposition seismic attribute to better visualize the 3D stratigraphic architecture of the system. This revealed a stratigraphic evolution from relatively few, wide isolated channel deposits in the lower Brushy to widespread, narrow channel deposits in the upper Brushy. Both channel architectures show low sinuosity and trend to the south and southwest. The low sinuosity of the channel deposits is interpreted to be a product of frequent channel avulsions. This caused the channels to be short-lived and immature, preventing enough sustained sediment-gravity flow activity to develop significant sinuosity. I interpreted the observed vertical change from isolated, short-lived, weakly confined channels to more numerous, relatively narrow channels, including distributary patterns organized into lobes as reflecting a backstepping of the depositional system. This backstepping stacking pattern has been previously recognized at multiple scales throughout the Brushy Canyon Formation. This is the first time that these patterns have been imaged in 3D seismic-reflection data, mapped in the subsurface, and checked against well log data

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Submarine channels are important conduits for sediment in deep marine environments, and understanding their formation is critical to modeling basin fill processes. Most models describing channel evolution focus on turbidity currents as the erosive and constructive force in channel initiation. However, slope failure and slumping can be significant drivers of channelization, particularly in upper slope and ramp environments. Determining the relative roles of slumping and erosion by turbidity currents can provide important insight into the timing of channelization and the geometries of subsequent deposits. Samples were collected from Guadalupe Mountains National Park from two primary localities at Salt Flat Bench (Figure 2). Three vertical sections were measured at both locations. A total of 16 samples were collected for petrographic analysis and X-ray fluorescence (XRF) imaging. Spectacular outcrop quality makes the Middle Permian Brushy Canyon Formation in Guadalupe Mountains National Park an ideal location for the study of early channel evolution. A detailed facies analysis of fine-grained channel deposits was conducted in the Upper Brushy Canyon Formation in the Salt Flat Bench outcrops. After channelization, an interval of relative condensation dominated by hemipelagic settling of organic matter and silt was followed by an interval of incomplete sediment bypass by turbidity currents. This sequence of events suggests that sea level was at a relative highstand at the time of channel inception, whereas channel inception by turbidity currents is expected during a lowstand. Slumping rather than erosion by turbidity currents is the most likely mechanism to have initiated a channel at the study area. There is no evidence for the existence for high energy currents until after the interval of condensation. However, the action of weak contour currents during early channel evolution is observed in outcrop and microtextural features. Early carbonate cementation of channel-lining silts may have stabilized the slump surface with respect to erosion by later turbidity currents.
