Quaternary Glaciations - Extent and Chronology

This book is the first of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial workers, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimate modelling. In order to provide the information for the widest-possible range of users in the most accessible form, a series of digital maps was prepared.The glacial limits were mapped in ArcView, the Geographical Information System (GIS) used by the work group. Digital maps, showing glacial limits, end moraines, ice-dammed lakes, glacier-induced drainage diversions and the locations of key sections through which the glacial limits are defined and dated are included. For major parts of Europe also the extent of the maximum Eemian transgression has been indicated. The digital maps in this volume cover all of Europe and parts of northwestern Siberia. Both overview maps and more detailed maps are provided.

The Application of Ichnology to Palaeoenvironmental and Stratigraphic Analysis

It has been increasingly realized by sedimentologist in the petroleum industry and academia that integration of ichonological information into sedimentological models, and vice versa, is one of the main means by which we can improve our understanding of ancient depositional environments. This volume aims to provide an analytical review of yhe ichnology of all major depositional environments and the use ichnology in biostratigraphic and sequence stratigraphic analysis, as well as highly refined palaeeoenvironmental studies. The remit of the book is achieved through a combination of review articles and novel research papers that outline methodologies and protocols for improving our understanding of ancient palaeoenvironments. Trace fossils from microscopic borings to dinosaur footprints are considered.
