Book excerpt: "Offering a solid introduction to the principles and applications of sedimentology and stratigraphy, author Richard A. Davis Jr. emphasizes the integration of these two areas and covers both modern and ancient depositional environments using modern examples and excellent illustrations. The Second Edition presents updated technical information, and offers a major reorganization of chapters to promote greater clarity and to place greater emphasis on more current topics. Additional content highlights: provides new approaches to basic analysis, including sequence stratigraphy; integrates genetically related depositional environments that share a common thread in concurrent chapters; discusses topics such as sedimentary processes and structures, the desert system, the fluvial system, the delta system, the barrier island system, reefs and the carbonate platform system, the deep ocean system, and much more." --

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 1971 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Eastern Shelf was a constructional platform developed on the margin of the sediment-starved Midland Basin during Late Pennsylvanian and Early Permian time. A mixed terrigenous-carbonate sedimentary province characterized the shelf during most of its history. Sediments were derived from highlands to the east and northeast. Along the outcrop in Eastland, Stephens, Young, and Jack counties, uppermost Pennsylvanian beds compose the Harpersville Formation, a boundary-defined rock stratigraphic unit within the Cisco Group. Harpersville facies extend westward into the subsurface 50 to 60 miles, where they grade into equivalent shelf margin carbonate and slope terrigenous facies. Preserved relief between the shelf margin and basin floor ranges from 600 to 1100 feet with dips of up to five degrees. Three depositional systems are recognized on the basis of gross lithologic composition and position relative to the shelf edges. They are the Cisco fluvial-deltaic system, the Sylvester shelf edge bank systern, and the Sweetwater slope system. The Cisco fluvial-deltaic system is composed of dip-fed fluvial-deltaic facies and associated strike-fed interdeltaic embayment facies. Eight deltaic lobe complexes have been mapped. The Sylvester slope system is composed of several slope wedges or fans each of which includes shelf margin, slope trough, and distal slope sandstone facies, as well as slope mudstone facies. Terrigenous sediments were transported across the shelf by prograding fluvial-deltaic channels, which locally extended through the shelf edge bank system and onto the slope where submarine fans were constructed into the basin. The Eastern Shelf prograded into the Midland Basin by local upbuilding through fluvial, deltaic, and shelf edge bank deposition contemporaneous with outbuilding by slope fan deposition. Sites of shelf construction shifted through time in response to sedimentary and structurally controlled abandonment of delta lobes. Extrabasinal controls such as eustatic sea level changes were of secondary importance in developing the depositional fabric of the shelf.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The term "carbon cycle" is normally thought to mean those processes that govern the present-day transfer of carbon between life, the atmosphere, and the oceans. This book describes another carbon cycle, one which operates over millions of years and involves the transfer of carbon between rocks and the combination of life, the atmosphere, and the oceans. The weathering of silicate and carbonate rocks and ancient sedimentary organic matter (including recent, large-scale human-induced burning of fossil fuels), the burial of organic matter and carbonate minerals in sediments, and volcanic degassing of carbon dioxide contribute to this cycle. In The Phanerozoic Carbon Cycle, Robert Berner shows how carbon cycle models can be used to calculate levels of atmospheric CO[2 and O[2 over Phanerozoic time, the past 550 million years, and how results compare with independent methods. His analysis has implications for such disparate subjects as the evolution of land plants, the presence of giant ancient insects, the role of tectonics in paleoclimate, and the current debate over global warming and greenhouse gases
