This book was released on 2011 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Richly fossiliferous strata of the Cincinnati area have a long history of study. An abundance of lithologic names have been applied to various shallow marine depositional facies across the Cincinnati Arch in Indiana, Kentucky and Ohio, U.S.A. The current study builds upon recent, high-resolution stratigraphic studies of the Edenian Stage, Kope Formation, and applies a similar approach to the Maysvillian Stage strata of the Cincinnati Arch. Strata of the Maysvillian Stage were deposited in shallower water conditions than the underlying Kope Fm., resulting in an increased localization of facies. Maysvillian Stage strata have previously been treated as a mosaic of local facies with little to no continuity or small-scale cyclicity; however, correlation of time-synchronous marker horizons and sequence stratigraphic units the Maysvillian Stage throughout the Cincinnati Arch demonstrates that this is not the case and suggests widespread, allocyclic controls on sedimentation. Based upon the documentation of widely traceable horizons the current study establishes a fourth order sequence stratigraphy for the Cincinnati Arch. As an independent test of lithologic-cycle correlation, the current study has utilized magnetic susceptibility in vertical successions, and attempts to quantify small scale cycles within the Maysvillian Stage. Magnetic susceptibility in combination with field observations has revealed previously overlooked unconformities, such as the basal Bellevue Mbr. unconformity, which oversteps the Miamitown Shale to the east of Cincinnati. In addition, intervals of relatively thick siltstone beds, commonly with soft-sediment deformation, are identified as an indicator of falling stage systems tracts, formed during forced regressions. In contrast, intervals of relatively compact skeletal pack and grainstones with evidence of condensation, such as hardgrounds indicate transgressive systems tracts. Using these criteria the current study provides a newly established fourth order sequence stratigraphic framework, and a reevaluation of third order depositional sequences on the Cincinnati Arch. Revisions include reinterpretation of key surfaces, some of which record flooding surfaces, previously identified as sequence boundaries, identification of previously unrecognized sequence boundaries, and replacement of "shazam" lines of imaginary facies transition by a more realistic framework of small-scale cycles. Empirical evidence of sea level variation within small-scale cycles, based upon sedimentary structures in shallow water facies, e.g., changes from mud-cracked strata to fully marine carbonate deposits, suggests sea-level change as the principal mechanism for small-scale cycle generation; widespread correlation of these cycles indicates an allocyclic forcing mechanism, probably eustasy. Differences in thickness of mudstone deposits between Cincinnatian units are attributed to tectonic and climatic changes occurring in the orogenic hinterland during the Late Ordovician, affecting the supply of fine-grained siliciclastics to offshore areas. Synthesizing sequence stratigraphy of the Cincinnati Arch with observation of coeval strata in New York, and the Southern Appalachians the current study also recognizes variations in the magnitude of base-level change to peripheral foreland bulge migration occurring during waning phases of the Taconic orogeny. Throughout the Cincinnatian, and other Paleozoic strata a three-fold motif of lithologic units has been observed: the current study offers a discussion of the naming of lithologic units and the hierarchical nature of depositional cycles associated with this phenomenon.

Download or read book Ichnology written by Luis A. Buatois and published by Cambridge University Press. This book was released on 2011-08-11 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ichnology is the study of traces created in the substrate by living organisms. This is the first book to systematically cover basic concepts and applications in both paleobiology and sedimentology, bridging the gap between the two main facets of the field. It emphasizes the importance of understanding ecologic controls on benthic fauna distribution and the role of burrowing organisms in changing their environments. A detailed analysis of the ichnology of a range of depositional environments is presented using examples from the Precambrian to the recent, and the use of trace fossils in facies analysis and sequence stratigraphy is discussed. The potential for biogenic structures to provide valuable information and solve problems in a wide range of fields is also highlighted. An invaluable resource for researchers and graduate students in paleontology, sedimentology and sequence stratigraphy, this book will also be of interest to industry professionals working in petroleum geoscience.

Available in PDF, EPUB and Kindle. Book excerpt: This book envisages a multi-proxy approach using stable isotopes, geochemical proxies, magnetic susceptibility and associated biotic events for paleoclimatic and paleoenvironmental interpretations of the Mesozoic sedimentary record of India. Mesozoic rocks of India record abnormal sea level rise, greenhouse climate, intensified volcanism, hypoxia in seawater, extensive black shale deposition, and hydrocarbon occurrence. The Mesozoic has also witnessed mass extinction events, evolution of dinosaurs, and breakdown of the supercontinent Pangea and the formation of Gondwana. Although the Mesozoic geology of India has witnessed significant progress in the last century, literature survey reveals a huge gap in knowledge regarding sequence stratigraphy, chemostratigraphy and key geological events. A synthesis of sedimentological, paleontological and chemical data is included to presenting a comprehensive understanding of the Indian Mesozoic record to students, researchers and professionals.

Download or read book Atlas of Trace Fossils in Well Core written by Dirk Knaust and published by Springer. This book was released on 2018-07-21 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with a well-balanced blend of high-quality photographs, figures and accompanying texts on the identification of trace fossils, both in core and in outcrop. Ichnological data has become increasingly important in sedimentological and paleoenvironmental interpretations, not only in the exploration and exploitation of hydrocarbons but also in the characterization of aquifers and in scientific drilling. Following an introduction to the study of trace fossils in core and an outline of ichnological basics, principles and concepts, the book provides detailed descriptions and interpretations of 39 trace fossils (ichnogenera) and associated features (such as bioturbate texture, plant roots and their traces, borings and pseudo-trace fossils) commonly encountered in well cores and in outcrop. The trace fossils are highlighted by their expression in well cores and illustrated with carefully prepared, eye-catching core photographs. This unique information is complemented by examples of trace fossils in outcrop, as well as relevant key figures from the literature. Each description is presented in a consistent manner, stating the ichnogenus name and author in the title, followed by sections on the morphology and size, ichnotaxonomy, substrate, appearance in core, similar trace fossils, producers, ethology, depositional environment, ichnofacies, age, and reservoir quality. An extensive list of references per chapter for further reading rounds out the book, which is based on the author’s continuous work with trace fossils in core over the past two decades.
Download or read book Recent Advances in Models of Siliciclastic Shallow marine Stratigraphy written by Gary J. Hampson and published by SEPM Soc for Sed Geology. This book was released on 2008 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Siliciclastic shallow-marine deposits record the interface between land and sea, and its response to a variety of forcing mechanisms: physical process regime, the internal dynamics of coastal and shelfal depositional systems, relative sea level, sediment flux, tectonic setting, and climate. These deposits have long been the subject of conceptual stratigraphic models that seek to explain the interplay between these various forcing mechanisms, and their preservation in the stratigraphic record. This volume arose from an SEPM research conference on shoreline-shelf stratigraphy that was held in Grand Junction, Colorado, on August 24-28, 2004. The aim of the resulting volume is to highlight the development over the last 15 years of the stratigraphic concepts and models that are used to interpret siliciclastic marginal-marine, shallow-marine, and shelf deposits.
