Phanerozoic Stromatolites II


Book Description

Precambrian stromatolites have received in depth, consideration from geologists and paleontologists; they were indeed searching for biosedimentary structures that were sufficiently characteristic and widely distributed to be considered as useful tools for stratigraphic correlation. Silicified stromatolites are also of interest as they contain preserved traces of ancient life. Calcareous Phanerozoic stromatolites have not received very much attention from geologists. Logan's too schematic morphological classification of 1964, was not so helpful to the knowledge of Phanerozoic stromatolites because neither their morphology nor their microstructure were studied in the same detail in which Proterozoic stromatolites have now been described. We therefore know little about the Phanerozoic stromatolites which, do, however, show an interesting range of diversification. A major questions stiII remaining to be answered include the history of stromatolite development and wether their morphology has "evolved" in addition to detailed information concerning Cenozoic nonmarine stromatolites which precipitate carbonate and the Recent giant stromatolites which trap particles. For these reasons Claude Monty, in 1981, launched the first volume of what was going to be a series on "Phanerozoic stromatolites" in order to describe their morphology, microstructure and paleoecology and to present them in their stratigraphic context.




Phanerozoic Stromatolites


Book Description

During the 2nd International Symposium on Fossil Algae, organized by the University P. & M. Curie, Paris, in April 1979, a special session was devoted to stromatolites; 29 papers were presented in French, English, or Russian. Among the papers selected originally, 16 were carried out to the final stage by their authors. They are presented here in their stratigraphical order. This selection does not pretend to cover the problem of Phanerozoic stromatolites in its entirety, but relates case histories. This should be the seed for further books analyzing and illus trating the paleoecology, the niche and the features of Phanerozoic stromatolites, namely throughout the Mesozoic and the Paleozoic, where the data are still scarce; this will lead to naturalistic views on the evolutionary features of Post Riphean stromes, and will sharpen tools to interpret their Precambrian ancestors. Let me introduce the papers. CLAUDE L. V. MONTY formalizes two basic types of crypt algal micro structures: the spongiostromate and the porostromate microstructures respectively; the rise of the latter around the Precambrian/Cambrian boundary represents a very significant step in the evolution of cyano bacterial microstructures and in their interaction with the environment. K. K. VERMA and G. BARMAN present a lower Phanerozoic stroma tolitic assemblage from Rajasthan associated with paralic alluvial fans fed by block faulting. Main stromatolite developments occurred during periods of low sedimentation and negligable tectonics, and formed in very shallow marine water. J.




Calcareous Algae and Stromatolites


Book Description

This volume provides a comprehensive overview of calcareous algae and stromatolites. It contains reviews by leading specialists of major groups, together with accounts of floras through time. It deals with marine and non-marine, benthic and planktic, and modern as well as ancient examples. As the first multi-authored review of the field ever published in English, it is an essential reference text for this complex field. It is designed for both postgraduate researchers and professional scientists who require up-to-date and authoritative information on these long-ranging organisms and fabrics which are of wide evolutionary, environmental and sedimentary significance.




Advances in Stromatolite Geobiology


Book Description

Stromatolites are the most intriguing geobiological structures of the entire earth history since the beginning of the fossil record in the Archaean. Stromatolites and microbialites are interpreted as biosedimentological remains of biofilms and microbial mats. These structures are important environmental and evolutionary archives which give us information about ancient habitats, biodiversity, and evolution of complex benthic ecosystems. However, many geobiological aspects of these structures are still unknown or only poorly understood. The present proceedings highlight the new ideas and information on the formation and environmental setting of stromatolites presented at the occasion of the Kalkowsky Symposium 2008, held in Göttingen, Germany.




Early Organic Evolution


Book Description

This volume is the final outcome of a conference designed to wrap up IOCP Project 157 (" Early Organic Evolution and Mineral and Energy Resources ") after a decade of prolific activity. The picturesque solitude of Maria Laach Abbey in the Eifel Mountains (FRO) provided the appropriate setting for a conclave of some 80 specialists from the various walks of the field who, during the week of Sept. 19 - 23, 1988, strived hard to define the state of the art in the principal segments of this Earth Science frontier. The following pages contain the essence of the conference transactions, giv ing a vivid cross-section of the activities pursued by IOCP Project 157 during its final years. The coverage of topics is not necessarily complete, but rather eclec tic in part. With regard to single papers dealing with modern analogues of ancient processes, the book title might even be considered a grave misnomer. Neverthe less, all contributions relate to the subject in the widest sense, and the reader should be reminded that much of the heterogeneity reflected by the volume de rives from the fact that it is primarily a research report from a highly inter disciplinary field rather than a textbook.




Encyclopedia of Modern Coral Reefs


Book Description

Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.




Microbial Sediments


Book Description

This volume provides a comprehensive overview of the rapidly developing field of microbial sediments, featuring excellent artwork. It contains authoritative and stimulating contributions by distinguished authors that cover the field and set the scene for future advances.




Sedimentology


Book Description

Sedimentology has seen many significant advances and changes over the past 40 years, ranging from facies modelling to sequence stratigraphy; chemostratigraphy to basin analysis; and the integration of studies of physical, chemical and, increasingly, biological processes in the interpretation and prediction of sedimentary environments and products. The subject is becoming ever more interdisciplinary and applied, and now has far more links to other physical sciences. Research and debate are continuing afresh as we move into this new interdisciplinary phase and promise many developments and increased uses of our subject. Now seemed a good time to publish a series of review papers concerning some key current areas of research. We hope that these papers will provide comprehensive starting points for those wishing to become acquainted with an area, act as stimuli for debate, and provide awareness and ideas for future research avenues. No issue of this sort can, of course, ever be truly comprehensive in its coverage: these reviews concern only selected snippets from the wide scope of sedimentology and each has, of necessity, been selective in its own area.




Palaeobiology II


Book Description

Palaeobiology: A Synthesis was widely acclaimed both for its content and production quality. Ten years on, Derek Briggs and Peter Crowther have once again brought together over 150 leading authorities from around the world to produce Palaeobiology II. Using the same successful formula, the content is arranged as a series of concise articles, taking a thematic approach to the subject, rather than treating the various fossil groups systematically. This entirely new book, with its diversity of new topics and over 100 new contributors, reflects the exciting developments in the field, including accounts of spectacular newly discovered fossils, and embraces data from other disciplines such as astrobiology, geochemistry and genetics. Palaeobiology II will be an invaluable resource, not only for palaeontologists, but also for students and researchers in other branches of the earth and life sciences. Written by an international team of recognised authorities in the field. Content is concise but informative. Demonstrates how palaeobiological studies are at the heart of a range of scientific themes.
