Westerhoff (Utrecht) Under the auspices of: CAI – Club Alpino Italiano AIQUA Associazione Italiana per lo Studio del Quaternario Foreword The Alps are at the origin of the basic ideas on the Quaternary: climate variability and glaciations. Since more than one century climatic-environmental changes and Quaternary stratigraphy are strictly connected. Under the pressure of the growing environmental problems, the exponential increase of the Quaternary studies progressively brought forward a highly complex time-space pattern of climate changes, driven both by external and internal forcing. Although no more the global reference area for the Quaternary, the Alps, at the boundary between the polar and the tropical systems and between the Atlantic oceanic and the Eurasian continental regions, still are a key area to unravel the entangled matter of facts and causes in the puzzle of climate variability. The stratigraphic research has a basic role to this purpose, both to scan in detail the local sequence of geologic events and to establish reliable correlations, at a local, regional and global scale. The new numerical dating techniques and the improved correlation methods are essential to the progress in this field. A consolidated and time-constrained stratigraphic framework is essential to the geologic mapping, to paleoclimatic and paleoenvironmental reconstructions, to pre-historic archaeology and to the history of man-environment interactions. This conference organized by the INQUA Subcommission on European Quaternary Stratigraphy aims properly to update and to promote the knowledge of the Quaternary stratigraphy and evolution of the Alpine region in the European and global framework. The conference will focus on five themes. - The glacial history of the Alps. Here, where the glacial theory was born, still many points need to be clarified, from the extent reached by ice in the different time slices, to the different responses of the various part of the chain, to the glacioisostatic vs. tectonic effects on erosion/denudation and recent rising of the Alps. - The last glacial-interglacial transition and the Holocene. Again the Alps, one of the first reference areas for the Late Glacial, still deserve intensified studies on this crucial turnabout of the Earth environment, exploiting all the different environmental records available. - Continental vs. marine Quaternary events, registration and correlation. The limit between land and sea has been for long time the boundary between two different Quaternary stratigraphies. Acknowledging the specific peculiarities of each record, the need to reconcile the two stratigraphies is requested, not only for correlations but also to understand the roles of ocean and continents in the climate variability. - Climatic and biotic evolution of the Alpine region and surrounding areas: Pliocene and Quaternary. Paleobiology keeps a traditional role in stratigraphy. The wealth of the Plio- Quaternary continental biotic records adds value to the bio-stratigraphic tools, allowing the understanding of the dynamics of the ecosystems under the pressure of climate changes. - The contribution of geochronology to the Pleistocene stratigraphy. Precise dating, with high time resolution, is essential both to long-distance correlation and to detect the high- frequency climate changes, those that are of major concern for the immediate future. The use of new methods in areas or time intervals poor or devoid of the materials requested by traditional methods, may again bring the Alps to the advanced front of the Quaternary studies. Two field trips will follow the conference. The first is dedicated to the long lacustrine sequences of the Lombard Prealps: well known since the late XIX century, new studies put in evidence their importance for the Early Pleistocene stratigraphy and climate and vegetation history, also with annually-resolved time intervals. With the second field trip, two of the major south-alpine morainic amphitheatres will be visited, concluding with the visit to the archaeological site of Fumane, where a highly detailed Late Pleistocene sequence has been excavated. The Milano group of Quaternary scientists is particularly glad to welcome the colleagues from the European countries and to have the opportunity to discuss together the South-Alpine Quaternary stratigraphic records.
