摘要
用ESR方法测定了系统采自山东荣成成山头“柳夼红层”11个样品的沉积年龄,表明它们是晚更新世以来沉积的受东北季风控制的海岸风成砂。此外,对沉积物中石英ESR测年的基本原理,石英Ge心信号测年的可行性,采集样品时应注意的问题等也进行了较深入的讨论。
Ages of 11 samples from 'Liukuang red beds 'of Chengshantou,Rongcheng County, Shandong Province were systematically determined by ESR method. It indicates that these samples are coastal aeolian sands deposited and controlled by northeast monsoon since Pleistocene. In addition,the basic principle of ESR dating for quartz in sediments, the feasibility of ESR dating by using Ge center of quartz in sediments and some attentive problems during collection of samples are also discussed.
