Major and trace elemnte chemistry of ODP Hole 107-652A and 107-654A (Table 1)

Upper Miocene sediments from two holes located in the Sardinian continental margin were analyzed to provide compositional data suitable for depicting their depositional environment and for paleogeographic reconstructions.
Samples from Hole 652A are sterile, calcareous-sandy siltstones which are rather similar considering their compositional parameters. They are markedly different from the silty-sandstones of Hole 654A which also show a high variability between them, particularly in terms of fossil and glauconite content (Sample 107-654A-45R-06, 066-068 cm), or mineralogical and chemical composition (Sample 107-654A-47R-01, 076-078 cm).
