年轻（<1000年）沉积物的光激发光（OSL）测年越来越多地用于各种晚全新世研究，作为确定当代沉积速率或沉积物沉积时间的手段。本文概述了光释光测年的基本原理，概述了年轻物质测年的具体问题，然后使用最近对年轻沉积物的应用来说明该方法在地貌学和现代沉积物地质学中的应用范围和潜力。这新一代的OSL年龄的整体可靠性进行检查，在可能的情况下，OSL年龄与独立的年龄控制。它的结论是，OSL年龄是准确的，因为没有证据系统的高估或低估。因此，光释光测年可以作为确定海岸带水系沉积物和海岸及内陆风成沉积物沉积时间的可靠年代学工具。我们的结论得到了越来越受欢迎的地貌学和地质学的光释光测年。
Optically stimulated luminescence (OSL) dating of young (<1000 years) sediments is used increasingly in a wide variety of late-Holocene studies as a mean of establishing contemporary sedimentation rates or the timing of sediment deposition. This paper provides a summary of the basic principles of OSL dating, outlines the problems specific to the dating of young material, and then uses recent applications to young sediments to illustrate the greatly increased scope and potential of the method in geomorphology and the geology of recent deposits. The overall reliability of this new generation of OSL ages is examined by comparing, where possible, OSL ages with independent age control. It is concluded that, the OSL ages are accurate, in that there is no evidence for systematic over- or under-estimation. It is our conclusion that OSL dating should be regarded as a reliable chronological tool for determining the time of deposition of water-lain sediments from the coastal zone, and aeolian deposits from both coastal and inland environments. Our conclusion is supported by the growing popularity of OSL dating in geomorphology and geology.
