dc.description.abstract | Experiments were designed to evaluate the behaviour of detritus during the leaching of impure carbonates by applying the U-Th
isochron technique. We used one natural detritus and a pure, well-dated CaCO3
, alone and in artificial mixtures. One set of
experiments was designed to study the effects of sample pre-treatment on the detritus and a second set to examine the effect of acid
attacks on both the carbonate and the detritus fractions in a mixture of constant proportions. For both sets of data, the extracted
fraction from the detritus was calculated for 238U, 234U, 230Th and 232Th and their constancy established. These conditions are
necessary to apply the L/L method [Schwarcz, H.P., Latham, A.G., 1989. Dirty calcites. 1.–Uranium-series dating of contaminated
calcite using leachates alone. Chemical Geology (Isotopes Geoscience Section) 80, 35–43] for U/Th dating. Finally, the L/L method
was applied to the artificial impure carbonate and the resulting age is found in agreement with the age of the pure carbonate sample.
We concluded that conditions of the L/L method to be applied for ageing impure carbonates hold. | es |
