Climate variability in the SE Alps of Italy over the past 17 000 years reconstructed from a stalagmite record SILVIA FRISIA, ANDREA BORSATO, CHRISTOPH SPÖ TL, IGOR M. VILLA AND FRANCO CUCCHI Frisia, S., Borsato, A., Spötl, C., Villa, I. M. & Cucchi, F. 2005 (November): Climate variability in the SE Alps of Italy over the past 17 000 years reconstructed from a stalagmite record. Boreas, Vol. 34, pp. 445-455. Oslo. ISSN 0300-9483.Stalagmite SV1 from Grotta Savi, located at the SE margin of the European Alps (Italy), is the first Alpine speleothem that continuously spans the past c. 17 kyr. Extension rate and d 18 O c record for the Lateglacial probably reflect a combination of temperature and rainfall, with rainfall exerting the dominant effect. Low speleothem calcite d 18 O c values were recorded from c. 14.5 and 12.35 kyr, during GI-1 (Bølling-Allerød) interstadial, which, in our interpretation, was warm and wet. The GS-1 (Younger Dryas) was characterized by a shift to heavier d 18 O c , coinciding with d 13 C c enrichment and extremely low extension rate (<8 mm/year). These characteristics indicate that GS-1 climate was cool and dry in the SE Alps. Calibration using historical data revealed that there is a positive d 18 O c /dT relationship. A 1 C rise in mean annual temperature should correspond to c. 2.85% increase of SV-1 d 18 O c . We reconstructed a slow and steady temperature rise of c. 0.5 C since 10 kyr BP, in broad agreement with reconstructions from pollen data for SE Europe. Stalagmite SV1 indicates that climate variability in the SE Alps has been influenced by the Mediterranean Sea for the past c. 17 kyr.

The paper aims to present the geology of the western part of the Classical Karst (NW Dinarides), located at the border between Slovenia and Italy. The work is based on archive, published and new data collected by Slovenian and Italian researchers within several scientific national and Cross Border Cooperation projects. The map, produced at a scale of 1:50,000, summarizes the lithological and structural setting and is supplemented by three geological cross-sections of the study area.ARTICLE HISTORY
