Abstract:

U-series and ESR dating techniques were applied to calcretes sampled at locations with a chronostratigraphic framework in Spain. ESR dating considering the organic signal at g = 2.0045 leads to an age overestimation up to 200 ka. The percentage of error decreases, however, with increasing age, so that this method may be more suitable to the dating of early Pleistocene samples. Despite the unique limitations of the ESR method to the dating of calcretes, only a differentiation of early, middle, and late Pleistocene calcretes is reasonable.
