"This volume presents current understanding of the mechanisms and environments of the formation of calcretes and palustrine carbonates. Through a series of specific field examples, papers in this volume illustrate the wide variety of potential applications of these types of deposits. The papers presented here cover a wide array of ages and environmental settings of calcrete and palustrine deposition and include many interesting applications, such as the climatic and geomorphic controls on calcrete formation, possible modern analogues for palustrine carbonates, the interplay between palustrine, pedogenic, and diagenetic processes, the utility of radio-isotopic methods for dating pedogenic carbonates, applications to understanding landscape evolution, and reconstruction of diagenetic sequences. The result is a state-of-the-art book on these deposits so common in the geological record and in recent environments."--Publisher's website.
The 35th International Meeting of Sedimentology supported by the International Association of Sedimentologists is an annual conference with global impact among the community of sedimentary geologists. Original scheduled at June 2020, the 35 the IAS Meeting of Sedimentology was postponed to June 21-25, 2021, and will be held virtually. The main convenor, Ondřej Bábek, is an employee of Palacký University Olomouc.
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.
This book is devoted to the ichnology of insects, and associated trace fossils, in soils and paleosols. The traces described here, mostly nests and pupation chambers, include one of the most complex architectures produced by animals. Chapters explore the walls, shapes and fillings of trace fossils followed by their classifications and ichnotaxonomy. Detailed descriptions and interpretations for different groups of insects like bees, ants, termites, dung beetles and wasps are also provided. Chapters also highlight the the paleoenvironmental significance of insect trace fossils in paleosols for paleontological reconstructions, sedimentological interpretation, and ichnofabrics analysis. Readers will discover how insect trace fossils act as physical evidence for reconstructing the evolution of behavior, phylogenies, past geographical distributions, and to know how insects achieved some of the more complex architectures. The book will appeal to researchers and graduate students in ichnology, sedimentology, paleopedology, and entomology and readers interested in insect architecture.
