This book was released on 2017-06 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our study documents the shelf, shelf-edge, slope, and basin-floor depositional facies characteristics, stratigraphic variations, and sedimentation trends of the Missourian Canyon Group and Virgilian-Wolfcampian Cisco Group across the southern Eastern Shelf and the adjacent Midland Basin. The Canyon Group (base Palo Pinto Limestone to top Home Creek Limestone) consists of an aggradational carbonate bank succession having locally prominent reef facies. Similar reef facies continued to accumulate during early Cisco sedimentation. The bank/reef interval, largely equivalent in age to the Horseshoe Atoll complex, is as much as 1,540 ft (469 m) thick in northeastern Coke County and forms an irregular, but distinct, shelf margin throughout the eastern part of the study area. Reef buildups are generally aligned at the margin but also occur as local pinnacles in the platform interior. Canyon basin-floor facies are equivalent to the lower part of the Cline shale ("Wolfcamp D") and consist primarily of dark, organic-rich (>2 percent organics) mudrocks. The overlying Cisco section comprises a series of 13 mudrock, limestone, and sandstone cycles (top Home Creek Limestone to top Coleman Junction Limestone), correlated from outcrop, that collectively form a progradational succession extending from the eastern edge (Bunger Limestone) to the central part of the study area (Coleman Junction Limestone). The top of the Home Creek Limestone coincides with a regional downlap surface for the progradational Virgilian lower Cisco shelf strata. Progressive upward decrease in height of shelf-margin clinoforms indicates that accommodation had markedly decreased during deposition of the upper Cisco Group. The Pennsylvanian-Permian (Virgilian-Wolfcampian) boundary is at the top of the Cline shale in the basin and slope provinces and just above the Crystal Falls Limestone in the shelf area. The thickness of the Wolfcampian section is regionally consistent at the shelf (~700 to 850 ft [~213 to 259 m]), expands markedly basinward to as much as 3,500 ft (1,067 m) into a regional depocenter of high accommodation and high sediment influx associated with slope sedimentation, and then thins into the basin proper (to

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic-carbon-rich shales of the Burket Member, Harrell Formation, were deposited at the toe and basinward of a series of alternately prograding and backstepping clinothems associated with the proto-Catskill Delta complex centered in or around western Susquehanna and Wyoming Counties, Pennsylvania. Distribution of organic-carbon-rich facies was controlled by changes in the delta complex driven by variations in rates of creation of accommodation and by a persistent topographic high centered in the area of western McKean and eastern Warren counties, Pennsylvania. Specifically, I interpret the middle and upper Tully Ls., the Burket Mbr., and the upper Harrell Fm. as comprising a single third order depositional sequence with the lower Tully Ls. being deposited during the falling stage of the preceding third order sequence. The middle Tully LS. represents the lowstand systems tract (LST), whereas the upper Tully Ls. and basal portion of the Burket Mbr. were deposited during the transgressive systems tract (TST). The upper portion of the Burket Mbr. was deposited during the highstand systems tract (HST) and the upper Harrell Fm. was deposited during the falling stage systems tract (FSST). The regional extent of parasequence sets, systems tracts, and the inferred depositional sequences, along with correlations with large scale transgressive sequences in other basins, suggest that base-level fluctuations were largely the result of allogenic forcing -- eustacy, climate, or regional thermal uplift or subsidence -- rather than autogenic forcing. Geochemical analysis suggests that bottom water conditions were oxic to suboxic at the time of Tully Ls. deposition but that conditions had become anoxic to euxinic by the time of Burket Mbr. deposition.

This book was released on 2018 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lower Cisco Group records the latest Pennsylvanian episode of progradational siliciclastic and aggradational carbonate deposition on the Eastern Shelf of the Permian Basin. This detailed study documents the spatial distribution of depositional systems in four of the six high-frequency cycles that constitute the lower Cisco Group. A dataset of 4,860 wells in an area about 4,900 mi2 (12,690 km2) is the basis for detailed correlations and subsurface maps for each cycle. Challenges in the definition and construction of a chronostratigraphic framework based on well-logs have been revisited. The use of the allostratigraphic approach proved to be an important tool for the construction of this stratigraphic framework. Three main depositional systems were the focus of this study: shelf-carbonate, HST delta, and incised-valley systems. Moreover, shelf-edge delta systems have been studied in a general way. Regional cross-sections show varied progradational or aggradational styles for contemporaneous depositional systems. Isochore maps enable the delineation of depositional systems. Furthermore, the recognition of four regional sediment pathways is possible from these maps. Multiple incised-valleys record variation in relative sea-level during the Late Pennsylvanian. This study identifies three fifth-order incised-valley systems, delineates their regional extent, and links them spatially to shelf-edge deltas. These incised-valley systems have the generic name of lower Hope sandstone; however, they have different ages and depositional styles. Four cores and seven thin sections enable characterization of the vertical lithologic succession, mineralogy, and diagenetic framework in these systems. This stratigraphic framework documents the locations of several depositional units of the lower Cisco Group on the Eastern Shelf. Their distribution is not uniform and depends on the amount of sediments supplied through the sediment pathways. Knowledge of these complicated patterns may be applied in the extension of under-developed oilfields and identification of new exploration targets.
