Abstract Establishing a common standardised growth curve (SGC) can substantially reduce the instrumental time for equivalent-dose (De) measurements in optically stimulated luminescence (OSL) dating. Several studies have indicated that different samples have different dose–response curves (DRCs) and therefore that it is difficult to construct a common SGC, although an SGC has been proposed in some cases. In this study, our aims were to construct a regional SGC based on small aliquots of sedimentary quartz from more than 100 samples from different sedimentary environments in the Jilantai Basin in North China and to investigate the applicability of different methods of establishing an SGC for the area. The precision of the De values of aliquots which were obtained using the SGC was compared with those obtained using the single-aliquot regenerative (SAR) protocol. Our results indicate the following: (1) for establishing an SGC using the regenerative normalisation (Re-SGC) method, selecting a suitable re-normalisation dose that is close to double the characteristic saturation dose, 2D0, can reduce the inter-aliquot/inter-sample variation in the form of DRCs within a larger dose range. (2) A common regional SGC can be established for the Jilantai area using the Re-SGC and least-squares normalisation (LS-SGC) methods, which provides reliable dating results within the 200 Gy De range.

建立华北吉兰台地区沉积物石英单等分OSL定年的通用标准化生长曲线

摘要 建立通用的标准化生长曲线 (SGC) 可以显着减少光学受激发光 (OSL) 测年中等效剂量 (De) 测量的仪器时间。几项研究表明，不同的样品具有不同的剂量反应曲线 (DRC)，因此很难构建一个通用的 SGC，尽管在某些情况下已经提出了 SGC。在本研究中，我们的目的是基于来自华北吉兰台盆地不同沉积环境的 100 多个样品的沉积石英的小等分试样构建区域 SGC，并研究不同方法在该地区建立 SGC 的适用性。 . 将使用 SGC 获得的等分试样 De 值的精度与使用单等分再生 (SAR) 协议获得的精度进行比较。我们的结果表明：(1) 为了使用再生归一化 (Re-SGC) 方法建立 SGC，选择接近特征饱和剂量 2D0 两倍的合适的重新归一化剂量可以减少等分/在较大剂量范围内以 DRC 形式出现的样本间变异。(2) 使用Re-SGC和最小二乘归一化(LS-SGC)方法可以为吉兰台地区建立一个共同的区域SGC，提供200 Gy De范围内的可靠测年结果。选择接近特征饱和剂量 2D0 两倍的合适的重新归一化剂量可以在更大的剂量范围内减少 DRC 形式的等分试样间/样本间变异。(2) 使用Re-SGC和最小二乘归一化(LS-SGC)方法可以为吉兰台地区建立一个共同的区域SGC，提供200 Gy De范围内的可靠测年结果。选择接近特征饱和剂量 2D0 两倍的合适的重新归一化剂量可以在更大的剂量范围内减少 DRC 形式的等分试样间/样本间变异。(2) 使用Re-SGC和最小二乘归一化(LS-SGC)方法可以为吉兰台地区建立一个共同的区域SGC，提供200 Gy De范围内的可靠测年结果。
