摘要: Abstract Thermoluminescence (TL) and Infra-red Stimulated luminescence (IRSL) studies were carried out on 21 samples from loess profiles at Dolni Vestonice. The IRSL measurements gave systematically lower equivalent doses (EDs) than the TL measurements; this could be due to inadequate preheat being applied former. Dose rate intercomparisons confirm view that alpha counting should finely ground material. Comparison of ED determination by regeneration additive dose methods did not suggest sensitivity increases bleaching, but for older ages underestimated compared with expected based correlation palaeosol stratigraphy framework provided deep sea oxygen isotope record. Using hypothesis decay a lifetime 150 ka suggests previous assigned palaeosols may correct.
