光释光(OSL)测年法被广泛应用于我国北方的黄土古土壤序列及其记录的气候环境变化、古地震、古人类遗址和考古研究等方面的测年和年代学研究。对中子活化分析(NAA)用于光释光测年所涉及到的地质样品中的铀、钍、钾含量的测定方法进行了优化,建立了微型中子源反应堆(MNSR)中子活化分析准确测定黄土样品中的铀、钍、钾含量的流程,为光释光测年提供了可靠的基础数据。
Oscillation of light (OSL) dating method is widely used in dating and chronology of loess paleosol sequences and recorded climate and environmental changes, ancient earthquakes, ancient human sites and archaeological research in northern China. The determination of uranium, thorium and potassium content in geological samples involved in photoluminescence dating by NAA was optimized. The neutron activation analysis of micro neutron source reactor (MNSR) was established. The accurate determination of uranium, thorium and potassium content in loess samples provides reliable basic data for optical-luminescence dating.
