This book was released on 1994 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permeability, the rate at which fluids move through a porous medium, affects the consolidation and reduction in porosity of a sediment with time and overburden pressure. Most marine clays consist of smectites and illites that are fine-grained and platey. In contrast, carbonate sediments are composed of multishaped, multisized components. In general, clay-rich sediments consolidate to lower porosities and are less permeable that carbonates at given overburden pressures. This difference is related to microfabric. Numerous samples recovered from the continental slope to midocean depths were consolidated in the laboratory, and permeabilities were determined directly by using falling head permeameters and indirectly by consolidation theory. In the marine clays, porosity values ranged between 1 x 10(exp-10) cm/s. In contrast, carbonate sediments with porosities between 60 and 40% had permeabilities that ranged between 1 x 10(exp-4) and 1 x 10(exp-7) cm/s. Sediments with varying percentages of carbonate content, but with a matrix of clay particles, fall with in the same range as the clays. At given porosities, permeabilities with in the carbonate sediments are determined by microfabric. For example, grain-supported samples have a higher permeability (1 x 10(exp-4) cm/s) than matrix-supported samples (1 x 10(exp-5) and 1 x 10(exp-6) cm/s). In general, matrix-supported carbonate sediments composed of aragonite needles have higher permeabilities (1 x 10(exp- 5) cm/s) than matrix-supported sediments of low-magnesian calcite composed predominately of coccoliths (1 x 10(exp-6) cm/s).

Available in PDF, EPUB and Kindle. Book excerpt: This volume is one outcome of the 6th International Conference on Paleoceano graphy (ICP VI). The conference was held August 23-28, 1998 in Lisbon, Portugal. The meeting followed the traditional format of a small number of invited oral presentations complemented by a large number ofcontributed posters. Over 550 participants attended, representing thirty countries and nearly 450 posters were presented. The invited speakers addressed the main themes of the 5oral sessions. The session topics were: Polar-Tropical and Interhemisphere Linkages; Does the Ocean Cause, or Respond to, Abrupt Climatic Changes?; Biotic Responses to Major Paleoceanographic Changes; Past Warm Climates; and Innovations In Monitoring Ocean History. This is the first time in ICP history that the Conference Proceedings are published. The aim of the organisers with the publication of this book is two-fold: to provide a useful review of the field and to document the ideas/controversies raised during the con ference that may stimulate future work. The book reflects the initial intentions of the conference, but it is not a conven tional conference proceedings, given that the papers have been reviewed by formal exter nal referees. Each of the conference topics is introduced by a review article designed to summarize the state of the art in each theme followed by articles prepared by the invited speakers. As with most conference proceedings, each theme is covered heterogenously. Some topics have all the expected contributions, others are less well covered.

Available in PDF, EPUB and Kindle. Book excerpt: Microbial carbonates (microbialites) are remarkable sedimentary deposits because they have the longest geological range of any type of biogenic limestones, they form in the greatest range of different sedimentary environments, they oxygenated the Earth’s atmosphere, and they produce and store large volumes of hydrocarbons. This Special Publication provides significant contributions at a pivotal time in our understanding of microbial carbonates, when their economic importance has become established and the results of many research programmes are coming to fruition. It is the first book to focus on the economic aspects of microbialites and in particular the giant pre-salt discoveries offshore Brazil. In addition it contains papers on the processes involved in formation of both modern and ancient microbialites and the diversity of style in microbial carbonate buildups, structures and fabrics in both marine and non-marine settings and throughout the geological record.

Available in PDF, EPUB and Kindle. Book excerpt: Carbonate rocks (limestones and dolomites) constitute a major partof the geological column and contain not only 60% of the world'sknown hydrocarbons but also host extensive mineral deposits. Thisbook represents the first major review of carbonate sedimentologysince the mid 1970's. It is aimed at the advanced undergraduate -postgraduate level and will also be of major interest to geologistsworking in the oil industry. Carbonate Sedimentology is designed to take the readerfrom the basic aspects of limestone recognition and classificationthrough to an appreciation of the most recent developments such aslarge scale facies modelling and isotope geochemistry. Novelaspects of the book include a detailed review of carbonatemineralogy, non-marine carbonate depositional environments and anin-depth look at carbonate deposition and diagenesis throughgeologic time. In addition, the reviews of individual depositionalsystems stress a process-based approach rather than one centered onsimple comparative sedimentology. The unique quality of this bookis that it contains integrated reviews of carbonate sedimentologyand diagenesis, within one volume.

Download or read book Calcretes written by V. Paul Wright and published by John Wiley & Sons. This book was released on 2009-04-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcretes are an important component of many ancient fluvial, lacustrine and shallow-marine carbonate sequences, and they are widely developed in many parts of the world at the present time. Calcretes are useful to the earth scientist involved in reconstructing ancient environments, palaeoclimates and palaeographics, and they may also reveal details of soil biota and chemistry. Over the last two decades the journal Sedimentology has published a number of articles on this subject and a compilation of them is presented here. In addition to the five main sections, this volume also includes an introduction to the subject that offers a review of recent work on calcretes. The collection of papers illustrates the range of calcrete occurrences and the great variety of textures and fabrics. This volume is authored and edited by experts and will serve as more than an introduction to the subject for geologists, soil scientists and geographers.

Download or read book Submarine Mass Movements and their Consequences written by Geoffroy Lamarche and published by Springer. This book was released on 2015-10-02 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive collection of state-of-the-art studies of seafloor slope instability and their societal implications. The volume captures the most recent and exciting scientific progress made in this research field. As the world’s climate and energy needs change, the conditions under which slope instability occurs and needs to be considered, are also changing. The science and engineering of submarine – or more widely subaqueous – mass movements is greatly benefiting from advances in seafloor and sub-seafloor surveying technologies. Ultra-high-resolution seafloor mapping and 3D seismic reflection cubes are becoming commonly available datasets that are dramatically increasing our knowledge of the mechanisms and controls of subaqueous slope failure. Monitoring of slope deformation, repeat surveying and deep drilling, on the other hand, are emerging as important new techniques for understanding the temporal scales of slope instability. In essence, rapid advances in technology are being readily incorporated into scientific research and as a result, our understanding of submarine mass movements is increasing at a very fast rate. The volume also marks the beginning of the third IGCP project for the submarine mass movement research community, IGCP-640 S4SLIDE (Significance of Modern and Ancient Submarine Slope LandSLIDEs). The Submarine Mass Movements and Their Consequences symposium is the biannual meeting under the IGCP umbrella.

Download or read book Stone in Architecture written by Erhard Winkler and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The readers of the first two editions of Stone: Properties, Durabi lity in Man's Environment, were mostly architects, restoration architects of buildings and monuments in natural stone, profes sionals who sought basic technical information for non-geologists. The increasing awareness of rapidly decaying monuments and their rescue from loss to future generations have urged this writer to update the 1973 and 1975 editions, now unavailable and out of print. Due to the 20-year-Iong interval, extensive updating was necessary to produce this new book. The present edition concentrates on the natural material stone, as building stone, dimension stone, architectural stone, and decorative field stones. Recently, the use of stone for thin curtain walls on buildings has become fashionable. The thin slabs exposed to anew, unknown complexity of stresses, resulting in bowing of crystalline marble, has attracted much negative pUblicity. The costs of replacing white slabs of marble on entire buildings with its legal implications have led construction com panies into bankruptcy. We blame many environmental problems on acid rain. Does acid rain really accelerate stone decay that much? Stone preservation is being attempted with an ever-increasing number of chemicals applied by as many specialists to save crumbling stone. Chemists filled this need during a time of temporary job scarcity, while the general geologist missed this opportunity; he was too deeply involved in the search for fossil fuels and metals.
