Abstract

²¹⁰Pb concentration in marine sediments of the Cariaco Trench (North-East of Venezuela) was measured through the analysis of ²¹⁰Po alpha emissions, which can be assumed to be in secular equilibrium with ²¹⁰Pb. The analysed sediment core has a length of 1.9 m. The results allowed to apply the CF:CS dating model (Constant Flux and Constant Supply). The sedimentation rate was estimated to be 0.25 cm/y. As far as we know this is the first α- dating carried out in the country, performed with an alpha spectrometer recently funded by the IAEA.
