摘要
第６届国际裂变径迹测定地质年代学术讨论会上推荐标准化刻度裂变径迹定年法，并推荐了几种定年标样。本文通过标准铀玻璃刻度系数定出值，利用外探测器法测定了国际标样中的３种桔石和两种磷灰石的年龄（ＦＣＴ２７．７±０．８Ｍａ，ＢＭ１６．１±０．５Ｍａ，ＴＲ６０．０±３．ＯＭａ，Ｄｕｒａｎｇｏ３０．８±１．９Ｍａ），在误差范围内与参考年龄一致。
The system calibration of fission track dating and some age standards were recommended at the 6th International Fission Track Dating Workshop. In this paper three zircon andtwo apatite standard samples are determined by using a dosimeter glass NBS-SRM612 and itscalibration constant b (b=ρd/σ·φ).The results obtained(27.7±0.8Ma for FCT,16.1±0.5Ma for MB,60.0±3. 0Ma for TR,30.8±1. 9Ma for Durango)are consistent with referenceage of the recommendation within the range of the error.
