我们提出了几种方法，直接日期的史前人类活动的点火在早期Gravettian婴儿埋葬地点的Krems-Wachtberg（奥地利）的热释光（TL）的方法。从多矿物细粒和橙红色热释光（R-TL）的细粒石英分离物，无论是从烘烤黄土直接下面的炉膛提取的蓝色热释光（B-TL）。B-TL测年遵循“经典”多等分-加性剂量（MAAD）方案。对于R-TL测年，测试了多等份再生（MAR）和缩短的单等份再生（SAR）方案。所有获得的热释光年龄在1-σ不确定度范围内一致，并将加权平均年龄33.9 ± 2.3 ka指定为最后使用壁炉，并推断婴儿埋葬。由于所有发光协议以及独立的测年方法的结果一致，因此排除了异常褪色。TL年龄与校准的放射性碳年龄的相关木炭，沉积物沉积的光释光测年和年龄估计获得的两个磁性测年方法是一致的。
We present several approaches to directly date the prehistoric human activity of lighting a fire at the Early Gravettian infant burial site of Krems-Wachtberg (Austria) by thermoluminescence (TL) methods. Blue thermoluminescence (B-TL) from polymineral fine grain and orange-red thermoluminescence (R-TL) from fine-grained quartz separates, both extracted from the baked loess immediately underlying the hearth were employed. The B-TL dating followed the “classic” multiple aliquot-additive dose (MAAD) protocol. For R-TL dating, the multiple aliquot-regenerative (MAR) and a shortened single-aliquot-regeneration (SAR) protocol were tested. All thermoluminescence ages obtained agree within 1-σ uncertainties and assign a weighted mean age of 33.9 ± 2.3 ka to the last use of the hearth and by inference to the infant burial. Anomalous fading is precluded due to the agreement of results from all luminescence protocols as well as with independent dating methods. The TL ages are consistent with calibrated radiocarbon ages on associated charcoal, OSL dating of the sediment deposition and with age estimates obtained by two magnetic dating approaches.
