Violet stimulation is a new development in optical dating which has been suggested to extend the upper age limit of optically simulated luminescence (OSL) dating of quartz. Despite the reported advantage, few validation tests and applications have been published so far. The present study investigated the violet stimulated luminescence (VSL) using a single aliquot regenerative dose (SAR) protocol and a multiple aliquot additive dose (MAAD) protocol. Sedimentary quartz samples from four archaeological sites in Europe with independent age controls spanning 40-900 ka were used, including Grotte Mandrin (France), Brooksby Quarry (UK), Cueva Negra del Estrecho del Rió Quípar (Spain) and Sima de las Palomas del Cabezo Gordo (Spain). The equivalent dose of a relatively young sample (~40 ka) was successfully determined. However, significant underestimations were observed for older samples with higher doses. These findings indicate the need for further development of the measurement protocol to date high-dose

评估紫光受激发光方案的测年潜力

© 2019 M. Sontag-González 等。由 sciendo 2019 出版。 紫光刺激是光学测年的一项新进展，有人建议延长石英光学模拟发光 (OSL) 测年的年龄上限。尽管有报告的优势，但迄今为止发布的验证测试和应用程序很少。本研究使用单等分再生剂量 (SAR) 协议和多等分附加剂量 (MAAD) 协议研究了紫光受激发光 (VSL)。使用了来自欧洲四个考古遗址的沉积石英样品，这些遗址的年龄控制范围为 40-900 ka，包括 Grotte Mandrin（法国）、Brooksby Quarry（英国）、Cueva Negra del Estrecho del Rió Quipar（西班牙）和 Sima de las Palomas del Cabezo Gordo（西班牙）。成功确定了相对年轻样品 (~40 ka) 的等效剂量。然而，对于具有较高剂量的较旧样品，观察到显着低估。这些发现表明需要进一步开发迄今为止的高剂量测量方案。
