Book excerpt: Anthony Fiorillo has been exploring the Arctic since 1998. For him, like many others, the Arctic holds the romance of uncharted territory, extreme conditions, and the inevitable epic challenges that arise. For Fiorillo, however, the Arctic also holds the secrets of the history of life on Earth, and its fossils bring him back field season after field season in pursuit of improving human understanding of ancient history. His studies of the rocks and fossils of the Arctic shed light on a world that once was, and provide insight into what might be.
Download or read book Coal and Coalbed Gas written by Romeo M. Flores and published by Elsevier. This book was released on 2024-01-24 with total page 770 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal and Coalbed Gas: Future Directions and Opportunities, Second Edition introduces the latest in coal geology research and the engineering of gas extraction. Importantly, the second edition examines how, over the last 10 years, research has both changed focus and where it is conducted. This shift essentially depicts "a tale of two worlds"—one half (Western Europe, North America) moving away from coal and coalbed gas research and production towards cleaner energy resources, and the other half (Asia–Pacific region, Eastern Europe, South America) increasing both research and usage of coal. These changes are marked by a precipitous fall in coalbed gas production in North America; however, at the same time there has been a significant rise in coal and coalbed gas production in Australia, China, and India. The driver for higher production and its associated research is a quest for affordable energy and economic security that a large resource base brings to any country like Australia’s first large-scale coalbed gas to liquid natural gas projects supplying the demand for cleaner burning LNG to the Asian-Pacific region. Since the last edition of this book, global climate change policies have more forcibly emphasized the impact of methane from coal mines and placed these emissions equal to, or even more harmful than, CO2 emissions from fossil fuels in general. Governmental policies have prioritized capture, use, and storage of CO2, burning coal in new highly efficient low emission power plants, and gas pre-drainage of coal mines. The Organization for Economic Cooperation and Development (OECD) countries and China are also introducing new research into alternative, non-fuel uses for coal, such as carbon fibers, nanocarbons, graphene, soil amendments, and as an unconventional ore for critical elements. New to this edition: Each chapter is substantially changed from the 1st edition including expanded and new literature citations and reviews, important new data and information, new features and materials, as well as re-organized and re-designed themes. Importantly, three new chapters cover global coal endowment and gas potential, groundwater systems related to coalbed gas production and biogenic gas generation as well as the changing landscape of coal and coalbed gas influenced by global climate change and net-zero carbon greenhouse gas emissions. FOREWORD When I reviewed the first edition of this book, my initial thought was, "Do we need another book on coal geology?" and then I read it and realised, "Yes, we need this book" and my students downloaded copies as soon as it was available. So now we come to 2023, and a lot has happened in the past decade. For a different reason we might ask if we still need this book, or even coal geoscientists and engineers, as the world aims for rapid decarbonisation of the energy sector and a reduction of coal as a feedstock for industrial resources, like steel manufacture.

Download or read book Depositional Environments of the Late Cretaceous Maastrichtian Dinosaur bearing Prince Creek Formation written by Peter Paul Flaig and published by . This book was released on 2010 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Prince Creek Formation contains first-order meandering trunk channels, second order meandering distributary channels, third-order fixed anastomosed(?) distributary channels, crevasse splays, levees, lakes, ponds, swamps, paleosols, and ashfall deposits. Trampling by dinosaurs is common. Most deposition occurred on crevasse splay-complexes adjacent to trunk channels. Rhythmically-repeating coarse-to fine-grained couplets in inclined heterolithic stratification suggest tidal-influence in channels. Cumulative to compound soils similar to Entisols, Inceptisols, and potential acid sulfate soils formed on levees, point bars, crevasse splays, and on the margins of lakes and swamps. Frequent overbank flooding is evidenced by silt and sand dispersed throughout paleosol profiles and fluctuations with depth in several molecular ratios. Drab colors, organics, siderite, depletion coatings, and zoned peds indicate waterlogged, anoxic conditions while ferruginous and manganiferous features, insect and worm burrows, and rare illuvial clay coatings and infillings suggest drying and oxidation of some soils. Repeated wetting and drying is tied to fluctuating river discharge. Marine influence is evidenced by jarosite, pyrite, and gypsum which become increasingly common up-section near the contact with the shallow-marine Schrader Bluff Formation. Recovered biota include Peridinioid dinocysts; algae; projectates; Wodehouseia edmontonicola; pollen from lowland trees, shrubs and herbs; Bisaccates; fern and moss spores; and fungal hyphae and indicates that all strata are Early Maastrichtian and that sediments become progressively younger from measured section NKT in the south to measured section LBB in the north. 40Ar/39Ar analysis of a tuff returned an age of 69.2 ± 0.5 Ma in the Sling Point outcrop belt. World-class dinosaur bonebeds are encased in muddy overbank alluvium overlying floodplains. No concentration of bone was found in channels. Bonebeds are laterally extensive except where truncated by distributaries. At the Sling Pont, Liscomb, and Byers bonebeds alluvium encasing bone exhibits a bipartite division of flow and a massive mudstone fades containing flow-parallel plant fragments that 'float' in a mud matrix suggesting deposition by fine-grained hyperconcentrated flows. Exceptional floods driven by seasonal snowmelt in the Brooks Range increased suspended sediment concentrations, generating hyperconcentrated overbank flows that killed and buried scores of juvenile dinosaurs occupying this high-latitude coastal plain. This unique killing mechanism likely resulted from fluctuating discharge tied to seasonality brought about by the near polar latitude of northern Alaska in the Late Cretaceous"--Leaves iii-iv.

Download or read book Depositional Environments of the Prince Creek Formation Along the East Side of the Toolik Rover Sagavanirktok Quadrangle North Slope Alaska written by Peter Paul Flaig and published by . This book was released on 2015 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 175-m-thick succession of nonmarine facies of the Prince Creek Formation along the east side of the Toolik River in the Sagavanirktok Quadrangle is interpreted as the deposits of meandering rivers and their associated floodplains. Facies consist of fine- to medium-grained sandstone, siltstone, mudstone, carbonaceous shale, and coal. Depositional environments of the Prince Creek Formation along the Toolik River include meandering river channels, levees, crevasse channels and crevasse splays, lakes, swamps, mires, and soil-forming environments. Sand bodies in the succession exhibit a low degree of interconnectedness and are encased in floodplain deposits. Floodplains were well preserved, extensively vegetated, and wet. Fine-grained successions containing abundant mud, silt, carbonaceous shale, and coal are up to 20 m thick in outcrops along the Toolik River and dominate the stratigraphy. This implies that lakes, marshes, mires and swamps likely persisted for prolonged periods in this region. The abundance of water-dependent floodplain facies coupled with the presence of isolated sand bodies encased in these finer-grained deposits indicates that the region likely experienced an extended period of elevated base level, possibly as the result of sustained high subsidence rates related to lithospheric loading in the evolving Brooks Range orogenic belt to the south.
Download or read book Marine continental Transitions in a Greenhouse World written by Dolores A. Van der Kolk and published by . This book was released on 2016 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Near horizontal (6° dipping) outcrop exposures of Upper Cretaceous (Santonian-Campanian) strata at Shivugak Bluffs in northern Alaska preserve an extensive record of a clinoform-topset system. These strata are subdivided lithostratigraphically into proximal shelf, deltaic, and shallow marine deposits of the Schrader Bluff Formation and lower delta plain, coastal plain, and fluvial deposits of the continental Prince Creek Formation. Shivugak Bluffs includes 400 m of continuous marine deposits overlain by 140 m of strata containing the marine–continental transition between the lower Schrader Bluff and Prince Creek formations. The marine-continental transition is one of the few outcrop expressions of an ancient, muddy, prograding river-dominated deltaic system that contains interdistributary bays that shoal upward into floodbasins with pedogenic modification. The lowermost 400 m of the lower Schrader Bluff Formation is divided into the Rogers Creek, Barrow Trail, and Sentinel Hill members interpreted as recurring deposits of river-dominated deltas comprising distributary mouth bars (DMBs), subaqueous terminal distributary channels (TDCs), interdistributary bays, medial delta front deposits, distal delta front deposits, and prodelta deposits interbedded with proximal shelf deposits. One interval within the Rogers Creek Member comprising the most hummocky cross-stratified (HCS) interval at Shivugak Bluffs is interpreted as wave-reworked DMB-TDC complexes or storm sheets. The Schrader Bluff (West Sak and Tabasco equivalent in the subsurface) and Prince Creek (Ugnu equivalent in the subsurface) formations are relevant to industry as outcrop analogs for numerous shallow, viscous- to heavy-oil reservoirs on the central North Slope, Alaska. From a reservoir perspective, a 36-m-thick subset of the Alaska succession within the Rogers Creek Member is compared to 36- and 34-m-thick wave-dominated successions of the Kenilworth and Grassy Members of the Blackhawk Formation in the Book Cliffs in eastern Utah. The Rogers Creek Member includes amalgamated DMB-TDC complexes (54%) with minor HCS wave-reworked deposits (46%). This succession is compared with the Kenilworth and Grassy members that exhibit predominantly swaley and HCS intervals (75–81%) with minor channel complexes (14–25%). The Blackhawk Formation, based on this analysis, is a poor reservoir analog for the lower Schrader Bluff Formation of Arctic Alaska.
