Book Description
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.

Book Description
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.
