摘要
本文研究了人工合成方解石和天然石笋样品的ESR谱及在α、β、γ射线辐照下的效应。由实验测出的TD和D值,计算出周口店第四地点石笋平均年龄为(6.0±0.8)×10~4年,此值与轴系法测得的平均年龄(6.5±0.4)×10~4年一致。
The ESR spectra of sythetic calcite and natural stalagmite and the ef-fect irradiated by α, β, γ rays have been studied in this paper.The average ESR age of the stalagmite at the Fouth Place, Choukoutiencave, is (6.0±0.8)×10~4a, calculated by means of the parameters of TD andD. This result is concordant with the averae age of (6.5±0 .4)×10~4a by U-series method.
