Book excerpt: Cyclothems record the sedimentary product of cyclicity in relative sea-level on either a regional or global scale, showing both regressive and transgressive phases. This study aims to contribute to our understanding of the sedimentary consequences of relative sea-level rise in a Carboniferous transgressive sequence in County Clare, western Ireland. The transgression in focus is at the top of the Tullig Cyclothem, and is exposed in several sections over a distance of 46 km. The aims of this thesis are to describe and interpret: 1) the detailed sedimentology and stratigraphy of the transgressive upper portion of the Tullig Cyclothem, 2) the nature (continuous or stepped) of, and controls upon, relative sea-level change, and 3) the paleoenvironmental transition from fluvio-deltaic to open marine conditions, and how this ties in to the overall evolution of the Western Irish Namurian Basin. These aims have been achieved by examination of all the outcrops of the transgressive upper Tullig cyclothem in County Clare, which show considerable lateral variation from north to south. One complete section of the transgressive Tullig is exposed at Trusklieve, where the sedimentary infill begins at the top of the fluvio-deltaic sandstone channels of the Tullig Sandstone. At this point, relative sea-level was at its minimum, and the beginning of the transgression is marked by symmetrical dunes, reworked dunes, and Zoophycos trace fossils. This surface is overlain by nearly 20 meters of unfossiliferous dark grey shales and siltstones, which are more organic rich and contain siderite nodules at their base, and are then topped by 4 meters of sandstone sheets, and finally a goniatite-rich fossil bed. This goniatite band marks the maximum relative sea-level within the Tullig cyclothem, and a fully marine environment. In terms of outcrop thickness, there is significant lateral variability between the nine outcrops studied in this thesis. The outcrops in the north (i.e. Furreera and Cliffs of Moher) are significantly thinner (less than 10 meters) than their southern counterparts, with the outcrop at Carrowmore Point being exceptionally thick (~50 meters). Additionally, the ratio of sandstone to siltstone also varies significantly between outcrops, and between one and three coarsening-upwards parasequences can be identified at these different locations. The outcrops that are centrally-located in the region (between Diamond Rocks and Carrowmore Point) possess the greatest thicknesses of sands and also up to three parasequences. At these localities, the presence of thick sandstones overlying shales and mudstones correlates strongly with the presence of mud diapirs, large-scale slumping and growth faults. The field study is used to propose a model for paleoenvironmental change through the upper transgressive portion of the Tullig Cyclothem: a transition from active fluvio-deltaic sands and coals of the upper Tullig Sandstone, followed by subaqueous delta plain muds and silts, progradational mouth bar sands, and finally the Reticuloceras stubblefieldi goniatite fossil bed. These changing paleoenvironments are interpreted in terms of the competition between relative sea-level change, which itself appears to be controlled by both eustatic sea-level change and local subsidence, and sediment supply, which is determined by both distance to source (as affected by relative sea-level) and local river channel avulsion and abandonment.

This book was released on 2016-04-28 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Carboniferous Shannon Basin of Western Ireland has become one of the most visited field areas in the world. It provides an ideal opportunity for examining a wide range of ancient sedimentary environments, including carbonate shelf, reefs and mud mounds, black shales and phosphates, and a spectrum of deep sea, shallow marine, fluvio-deltaic and alluvial siliciclastic sediments. The area boasts extensive outcrops and some of the most renowned sections through turbidites, large-scale soft sediment deformation features and sediments that display a response to tectonic and sea-level controls. This field guide provides the first synthesis of the principal localities in this area of Western Ireland, and presents an easily accessible handbook that will guide the reader to, and within, a wide range of sedimentary facies, allowing an understanding of the evolving nature of the fill of this Carboniferous basin and the context of its sedimentary and tectonic evolution. The guide summarizes recent and new work in the area by a range of authors and outlines issues of current debate concerning the Shannon Basin and its palaeoenvironmental interpretation. The field guide will find extensive use in teaching and research by academic researchers, professional and amateur geologists, as well as by applied geologists, geophysicists and reservoir engineers who use these outcrops as analogues for subsurface reservoirs in many areas of the world.

Available in PDF, EPUB and Kindle. Book excerpt: Principles of Sequence Stratigraphy, Second Edition presents principles to practical workflow that guide applications in a consistent manner that is independent of model, geological setting and the types and resolution of the data available. The book explains the points of agreement and difference between the various approaches to sequence stratigraphy, while also defining the common ground that affords the standard application of the method. This enables the practitioner to avoid nomenclatural and methodological confusions and apply sequence stratigraphy. The text is richly illustrated with hundreds of full-color diagrams and examples of outcrop, borehole and seismic data. The book's balanced approach helps students and professionals acquire a sound understanding of the concepts and methodology. It will appeal to geologists, geophysicists and engineers with interest in basin analysis, stratigraphy and sedimentology, as well as in all economic applications that concern the exploration and production of natural resources, including water, hydrocarbons, coal and sediment-hosted mineral deposits. Updates the award-winning first edition in all aspects of sequence stratigraphy, from the underlying theory to the practical applications Presents the standard approach to sequence stratigraphic methodology, nomenclature, and classification; the role of modeling in sequence stratigraphy, and the difference between modeling and methodology Discusses the roles of scale and stratigraphic resolution in sequence stratigraphy, and the workflow that affords a consistent application of the method irrespective of the types of data available Describes the three-dimensional nature of the stratigraphic architecture, and the variability of stratigraphic sequences with the tectonic setting, depositional setting, and the climatic regime Illustrates all concepts with high-quality, full-color diagrams, outcrop photographs, and subsurface well data and seismic images
