【摘要】 影响石英矿物释光灵敏度变化的因素很多,其中退火温度与辐照剂量是非常重要的两个因素.石英热释光灵敏度校正,往往依据沉积物中的石英颗粒来源的多样性而存在多种校正方法,也常常因地域和沉积物特征而异,校正方法并不统一.在释光测年中,灵敏度的校正是必须考虑和涉及的问题,需要全面认识石英的灵敏度变化的机制、特征、监测和校正等因素.本文利用天然石英岩脉进行石英热释光灵敏度检测,实验结果显示,温度低于400℃时,反复的热释光实验,不能引起石英灵敏度的变化,温度达到500℃时,反复测试后热释光灵敏度趋向于稳定.更多还原

【Abstract】 A lot of factors affect the thermoluminescence sensitivity of quartz. Among these factors, the annealing temperature and the irradiation dose are important. The various sources of quartz generate various methods of sensitivity correction. The sensitivity correction must be considered during the thermoluminescence dating. Then the changing mechanism and characteristics of the sensitivity need to be fully understood. This paper conducts sensitivity measurements of quartz from quartz vein. The experimental results show that there is no sensitivity change when the repeated thermoluminescence experiments below 400 ℃,while the thermoluminescence intensity tends to be saturated as the repeated thermoluminescence measurements of 500 ℃.更多还原
