Ricostruzioni paleoclimatiche del peri-adriatico attra verso speleotemi: primi risultati.

Abstract : In the framework of a PhD thesis at the University of Bologna and the University of Savoie (France), and in collaboration with the University of Melbourne (Australia), an ambitious scientific project is being carried out with the aim of finding palaeoclimatic records in speleothems sampled in caves of Italy and the Dinaric Karst. In this first sampling phase, thanks to the collaboration with local cavers, already broken stalagmites and flowstones have been taken in caves of Apulia, Emilia-Romagna, Trieste, Slovenia, and Bosnia Erzegovina. The samples have been cut along their length and polished. The bottom and top of the most promising samples (with well visible growth layers, clean primary calcite, without evident signs of recrystallization) has been dated to get their age of growth. The following microdrill sampling has allowed to take powders to be analysed at Mass Spectrometer for the stable isotopes of oxygen and carbon. These studies will allow to reconstruct the climate of the past in the areas of these caves, delivering a valid contribution to the palaeoclimate studies in the Central Mediterranean.
