Caratterizzazione geochimica ed isotopica del MIS 21 e al limite Brunhes-Matuyama (MIS 19) nella sezione di Valle di Manche (Calabria)

Aims of this Thesis are the stable oxygen and carbon isotope analysis of the foraminifer tests of the benthic species Uvigerina peregrina collected from the MIS 21 sediments of the Valle di Manche section (Calabria, Southern Italy), as well as addressing critical isssues concerning the positioning of the Matuyama-Brunhes (M-B) paleomagnetic reversal (MIS 19) based on XRD and 10Be analyses. Geochemical analyses were performed at a 10-cm resolution, which confirmed the trend shown by previous low-resolution investigations and improved the available dataset. X-ray diffraction analyses and the 10Be data suggest that the stratigraphic position of the M-B reversal revealed by conventional paleomagnetic studies (mid-MIS 19) should be confirmed.
