Abstract

In view of a decade of progress in ESR dating we have revised the ESR chronology of Border Cave. A detailed gamma ray survey in 1994 and newly calculated beta attenuation data led to total dose rate estimations that are between 0 and 30% smaller than previously estimated. Accordingly, the resultingESR age estimates are between 0 and 30% older. The ESR dates are now in good agreement with independent age estimates, particularly C-14 and amino acid racemization. New ESR dates for the lowermost dated sedimentary layer, 5WA (white ash), indicate that the sedimentation of the sequence started around 200 ka ago. (C) 2001 Academic Press.
