Plio-Pleistocene scanning x-ray fluorescence (XRF) data from ODP Site 967, Eastern Mediterranean


Mediterranean sediments record past changes in North African aridity/humidity changes (so-called 'Green Sahara periods') on orbital timescales. These changes are reflected in the alternating accumulation of organic carbon-rich and aeolian dust enriched sediments, and negative stable oxygen isotope excursions. Here we document these changes over the past 5 million years using scanning x-ray fluorescence (XRF) of ODP Site 967 sediments, measured with a 3rd generation Avaatech XRF core scanner. Element counts were converted into element concentrations for Al [ppm], Si [ppm], S [ppm], K [ppm], Ca [ppm], Ti [ppm], Fe [ppm], Sr [ppm], Zr [ppm] and Ba [ppm], based on a multivariate log-ratio calibration.

Caution values in sediment slump interval in Hole A sections 6H5-110 to 7H4-60 and in Hole B sections 7H4-114 to 7H5-63 (equivalent to 62.83 to 63.82 metres CCSF-offspl depth).
