U- and Th-series disequilibria in coastal infill sediments from Praia da Rocha (Algarve Region, Portugal) : a contribution to the study of late Quaternary weathering and erosion

Authors(s) and Affiliation(s)



U- and Th-series disequilibria observed in a sequence of infill sediments from Praia da Rocha, southern Portugal, were used in combination with geochemical and particle size data to investigate sediment provenance with a view to resolving the late Quaternary weathering and erosion history of the Algarve region, and the stratigraphy of coastal karstic exposures of the Faro/Quarteira (FQ) formation. The red infill units can be distinguished from the brown and buff units on the basis of their lower residual U- and Th- concentrations, their differing post-depositional histories, and their greater degree of sediment processing.
