Reliable ages are required in the Earth and archaeological sciences. Luminescence dating is a flexible geochronological technique for diverse deposits. It exploits the radiation-induced thermally (TL) and optically stimulated luminescence (OSL) emissions from minerals exposed to sunlight before burial. Recent technical developments have made feasible OSL dating of small samples (e.g., individual sand grains) and sediments deposited during the past 0.5-1 million years. We request funds for a Risø TL/OSL system with single-grain attachment to resolve the timing of sea-level, climate and landscape changes, and the chronology of human evolution and dispersal, in Australia and Southeast Asia.

地球科学和考古学需要可靠的年龄。发光测年是一种适用于不同矿床的灵活地质年代学技术。它利用了埋藏前暴露在阳光下的矿物的辐射诱导热（TL）和光致发光（OSL）发射。最近的技术发展使小样品的光释光测年变得可行（例如，在过去的50 - 100万年中沉积的单个沙粒）和沉积物。我们申请资金用于单颗粒附着的RisketTL/OSL系统，以解决澳大利亚和东南亚海平面，气候和景观变化的时间，以及人类进化和扩散的年表。
