OSL-Dating: Constraining the Pleistocene environmental history of the Atacama: Extending the age range of luminescence dating (D05)

该项目旨在将发光测年的年龄范围从~0.2-0.4 Ma扩展到1 Ma。阿塔卡马的景观以碎屑沉积为主，发光测年提供了一种广泛适用且通用的技术来限制环境变化的时间。扩大年龄范围将使来自其他子项目的地质年代学方法之间的时间差距得以跨越，例如，放射性碳测年的上限为~50 ka，宇宙成因埋藏测年的下限为~0.5 Ma。

This projects aims to extend the age range of luminescence dating from ~0.2-0.4 Ma towards 1 Ma. The landscape of the Atacama is dominated by clastic deposits, and luminescence dating offers a widely applicable and versatile technique for constraining the timing of environmental changes. Extending the age range will enable the temporal gap between geochronological methods from other sub-projects to be spanned, for example, whereas the upper limit of radiocarbon dating is ~50 ka, the lower limit of cosmogenic burial dating is ~0.5 Ma.
