Border Cave revisited: a revised ESR chronology.
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 resulting ESR age estimates are between 0 and 30% older. The ESR dates are now in good agreement with indep...
متن کاملBorder Cave
1941-1942, many Middle Stone Age industries were revealed. In addition, an infant burial was found in the assemblage. This finding lead archeologists to think that there may have been earlier hominid habitation in the Border cave site. Geologist H. B. S. Cooke did geological studies of the Border Cave assemblages. In 1974, a hominid mandible was found during an excavation along with younger MSA...
متن کاملBorder Cave
Border Cave exhibits a detailed sequence of MSA strata, with probable Homo sapiens sapiens remains within these layers, arguing for an early appearance of modern humans in South Africa. Supporters of an early appearance place hominids BC1, 2, and 3 at ~115 kyr by correlation to C 14 dated soils (Butzer et al, 1978), while skeptics, using ERS methods, believe these individuals are younger than 9...
متن کاملDiagenesis of bone from Border Cave: implications for the age of the Border Cave hominids
Hominids from the site of Border Cave purportedly provide direct evidence for the early emergence of anatomically modern humans (AMH) in Southern Africa. ESR dating of Border Cave faunal enamel has confirmed the antiquity of the sediments, although questions persist regarding the provenience of the hominid specimens. Here we establish that, at Border Cave as elsewhere, bone mineral crystallinit...
متن کاملIntrapersonal subspace analysis with application to adaptive Bayesian face recognition
We propose a subspace distance measure to analyze the similarity between intrapersonal face subspaces, which characterize the variations between face images of the same individual. We call the conventional intrapersonal subspace average intrapersonal subspace (AIS) because the image differences often come from a large number of persons. We call an intrapersonal subspace specific intrapersonal s...
