Book excerpt: The Swedish island of Gotland, in the Baltic, has attracted much attention of many geologists. Gotland is built up by a Middle Palaeozoic table-land, with an average height of 20-30 m, but with some higher hills in the inland and with steep cliffs along part of the coast. The Middle Palaeozoic strata consist primarily of limestones and marlstones. For a good understanding of the sedimentary succession of Gotland, it is important that the distribution of all the different kinds of sediments should be carefully mapped, and their faunal contents to be intensively studied. This book includes the survey and ideas gathered along with important data about the stratigraphy and reefs of Gotland. It presents description of the Baltic area, development of the stratigraphical subdivision of the Middle Palaeozoic of Gotland, and some tectonic and pseudo-tectonic phenomena. Stratified and unstratified sediments are presented along with a number of palaeoecological observations on Gotlandian fossils. Some comparisons of the reefs of Gotland with reefs in a few other areas are also examined.

Download or read book Palaeozoic Reefs and Bioaccumulations written by J. Javier Álvaro and published by Geological Society of London. This book was released on 2007 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological record contains a fascinating diversity of reefs and shell accumulations. As with many other biosedimentary structures, their facies characterization requires careful observation at outcrop and sample scale, and in thin-section to provide information about the global geometries, fabrics and textures respectively. This collection of papers encompasses the breadth of sedimentary geometries and facies displayed by Palaeozoic reefs, shell accumulations, and transitional composite deposits. The definition of reefs and shell concentrations has given rise to variations in nomenclature. The papers in this volume cover specific problems regarding the nomenclature and facies characterization of reefs, shell accumulations and transitional composite deposits. However, rather than attempt a complete revision of terms, the authors have touched on some of the important issues at this stage of development in the field: the main climatic, environmental and evolutionary factors that controlled the Palaeozoic development of shell accumulations and reefs.

Download or read book A New Silurian Llandovery Telychian Sponge Assemblage from Gotland Sweden written by Freek Rhebergen and published by John Wiley & Sons. This book was released on 2014-02-27 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: A newly discovered, diverse sponge fauna of early Silurian age, is described from Gotland, Sweden. This is the first Silurian sponge assemblage known from Baltica, and the only diverse Llandoverian assemblage known worldwide. The fauna includes 20 genera and 29 species, of which three genera and six species are new. Eighteen species are new to Baltica. The fauna shows strong similarities to later Silurian assemblages in Arctic Canada, but one endemic species comprises ca. 50% of the fauna. The fauna shows that lithistid sponges recovered well from the late Ordovician extinction in some areas, and became widely spread in the early Silurian. In contrast, non-lithistid sponges like, such as hexactinellids, appear to have evolved rapidly during the Late Ordovician – early Silurian interval, and some modern groups probably originated in inshore habitats.

Book excerpt: Excerpt from On the Silurian Gastropoda and Pteropoda of Gotland In spite of the certainty of many unavoidable failings and shortcomings, which as pointed out. Above, follow from the nature and conditions of the material, I ventu red to take up this study when it was found how unexpectedly rich and varied were the forms entombed in the Silurian strata of Got-land, and thanks to the munificence of the Royal Swedish Academy of Sciences it has now been brought to its conclusion. Though fragmentary in many respects this memoir may serve in some degree as a star ting point for future labours in the same field.
