Stratigraphy Quo Vadis?
The 1984 published results if an IUGS symposium, topics of the 12 chapters in this volume include: Marine stratigraphy from Continents and oceans; Problems in seismic stratigraphy; Paleobathymetry of Pelagic depositional enfironments; Pleistocene deep-sea sediment stratigraphy; Marine Cenozoic stratigraphy; Transgressonal warming and deglaciation; Messinian event; Events of the Mid-Cretaceous; Stratigraphic significance of storm beds; Ecostratigraphy; Numerical age of system, series, and stage boundaries of the Phanerozoic column, and Comments and recommendations.
It is well-known that stratigraphy tries to arrange all rocks in chronological order according to their inorganic and organic characteristics and it attempts to produce a time scale to date geological processes and events. Therefore, it is at the heart of geology as a historical science.
Absolute radiometric dating delivers the framework of earth history and is the base of investigating the gross speed of processes like tectonic movements or organic evolution. However, up to now, only about 300 figures are available for the last 600 million years. Therefore, much refinement is needed by classical or new biostratigraphic methods, and by statistical conclusions from sediment thickness and sedimentation rates down to annual layers, paleomagnetic and other investigations.
