I am therefore infinitely grateful to the Australian Government for giving me the opportunity to do a PhD and spend 4 wonderful years in this beau- tiful country that I now call home. I also acknowledge the financial support, during the last two years of my PhD, through a Post- graduate Research Award from the Australian Institute of Nuclear Science and Engineering (AINSE). My deepest and sincere gratitude goes to Silvia Frisia and Andrea Borsato my principal super- visors at the University of Newcastle, because during these four years I received a great super- efficient supervision and help every time I needed it. I felt always supported, encouraged and motivated and I have been working in a positive environment, which helped me a lot to get through all the typical ups and downs of a PhD. Thanks for having trusted me for this postgraduate project. A personal thanks for Silvia that, apart of being very competent in her job as professor and students supervisor, for me has been a friend and a point of reference. I should probably say an downunder-mum. Thanks for all the happy moments, the dinners at your place, our conversa- tion about life and Italy (I will never, never forgot your sincere and wise advices) and all the lunch-boxes you prepared many times for me. Andrea, un grazie personale also for all the laughs and funny moments shared together and especially, for all the speleo-adventures! I had so much fun mamma mia! I am also very thankful to Russell Drysdale for all the (tons) of isotopes analyses I could do at his lab at the University of Melbourne, during these four years. Thanks Russ for being always so welcoming, friendly and helpful; I have always felt like one of your PhD student. Thanks also to John Hellstrom (my co-supervisor) and Petra Bajo from the University of Mel- bourne for their help during the U-Th dating and for running the age-models. I am also grateful for the support and supervision received at ANSTO from Floriana Salvemini, Jitendra Mata and Vladimir Luzin. Thanks to Hugh Dunstan (University of Newcastle) who facilitated access to the fluorescence microscope. Thanks also to Sandro Montanari from the Osservatorio Geologico di Coldigioco, Sandro Mar- iani, Nereo Preto for their support during the fieldtrips at Frasassi cave and for all the good moments spent together during the speleological campaigns. Thanks to the Direnzione Regionale, the Soprintendenza Archeologica della Puglia and the municipality of Altamura for giving access and allowing sampling at Lamalunga cave. Thanks to the guys of the Centro Altamurano Ricerche Speleologiche (CARS) for assisting during the field work. Especially thanks to Giovanni Ragone for being very nice and welcoming with us.
