摘要
用ＥＳＲ技术测试了１３个辽河盆地下第三系砂岩层样品中石英的氧空位浓度，发现它们和所接受的总剂量（可换算成沉积年龄）密切相关。在此实验基础上提出了辽河含油气盆地第四纪前沉积物的ＥＳＲ测年模式。沉积物中石英的氧空位浓度是一种新的Ｍａ时间尺度的地质计时计。
The concentrations of oxygen vacancies in 13 quartz samples from the Lower Tertiary sandstone in Liaohe Basin were measured by ESR technique.It is found that the concentration of oxygen vacancies in quartz is strongly correlated with total absorbed dose of quartz.Based on the experiments,the model on ESR dating of the pre Quaternary sediment is suggested.The concentration of oxygen vacancies in quartz of sediment would be a new geochronometer on Ma time scale and become an effective tool of stratigraphic division.
