“…The Lake Valley illustrates the potential dimensions and lateral continuity for carbonate submarine fans-at least 14 to 20 km in length and >5 km wide-dimensions limited by outcrop exposure. Facies trends within fans may also be significant, with thick, amalgamated carbonate gravels and sands in the proximal fan-potential barriers to hydraulic fracture propagation (Wicker et al, 2018)-while distal regions are increasingly mud-rich with more finely interbedded mud-dominated and grain-dominated deposits-a potential reservoir facies (Kvale et al, 2020). These facies transitions occur over short distances-for example, the Tierra Blanca changes from 23% mud-dominated facies to 50%, over a 1 km distance in Alamo Canyon (Table 4).…”

“…Permian Basin, Neuquén Basin, Western Canada Sedimentary Basin), and deep‐water carbonate deposits are important components of those plays (Blanco et al, 2020; Kvale et al, 2020; Whalen et al, 2000). At the edges of basins, thick amalgamated carbonates shed from platforms commonly define the edges of productive plays and can act as barriers to hydraulic fracture propagation within the play (Wicker et al, 2018; Zhu et al, 2016). Where carbonate sediment‐gravity flow deposits are more finely interbedded with mixed‐lithology mudrocks (e.g.…”

Deepwater carbonate deposition is relatively poorly understood but an area of vigorous research in academia and industry, where these deposits are a significant component of many unconventional petroleum reservoirs. Recent studies of modern deepwater carbonates have highlighted the wide variety of depositional processes, sediment types and resultant geomorphology; however, well‐documented outcrops of ancient systems, their rock types and architecture are relatively sparse. The Mississippian Lake Valley Formation provides world‐class exposures of slope‐basinal carbonate deposits. The Tierra Blanca and Doña Ana members comprise submarine fans that are >14 to 20 km in length, >5 km wide, and exposed in strike and dip view, affording a unique opportunity to constrain the architecture, rock types and sedimentary processes. Tierra Blanca and Doña Ana sedimentation was dominated by crinoids shed from an up‐dip platform and supplemented by sediments sourced locally from Waulsortian mounds. Depositional processes include turbidity flows, debris flows and hybrid sediment‐gravity flows. The Tierra Blanca submarine fan thins towards its lateral flanks and distal fringe, where deposits become more mud‐dominated, gravelly grain‐supported flows are less common, and fewer beds have scoured bases. In proximal settings, bed tracing complemented by measured sections allow mapping of stratal surfaces and identification of stories, elements and complexes. The Tierra Blanca evolved from more unconfined to confined deposition. Point‐sourced deposition of the Tierra Blanca fan required a funnelling mechanism, likely due to bathymetry created by Waulsortian mounds or possibly a platform margin re‐entrant. Outcrop exposures illustrate that younger Doña Ana submarine fan deposits onlap onto, and compensationally stack with, the thickest portions of the antecedent Tierra Blanca fan. These outcrops illustrate both similarities and differences between carbonate and siliciclastic gravity flow deposits. Similarities include comparable deposit types, depositional processes and architecture; differences relate to hydrodynamics of carbonate grains, funnelling mechanisms for point‐sourced deposits and sequence stratigraphic forcing.
