| 摘 要： | 利用多接收器等离子体质谱仪(MC-ICPMS)和193nm准分子激光器联用技术,对GJ-1、Temora、91500和Mud Tank四个标准锆石的Hf同位素组成进行测试,并通过指数方法进行同质异位素干扰校正,测得它们的176Hf/177Hf比值分别为0.282006±24(n=159, 2SD)、0.282684±46(n=20, 2SD)、0.282305±32(n=20, 2SD)和0.282509±25(n=48, 2SD)。测定结果与文献报道的值在误差范围内一致。

| Abstract: | Hf isotopic compositions of four standard zircons, i.e., GJ-1, Temora, 91500 and Mud Tank, were analyzed using MC-ICPMS(Neptune) coupled with excimer laser ablation system (New Wave 193nm FX). The 176Hf/177Hf ratios obtained are 0.282006±24(n=159, 2SD) for GJ-1, 0.282684±46(n=20, 2SD) for Temora, 0.282305±32(n= 20, 2SD) for 91500, and 282509±25(n=48, 2SD) for Mud Tank respectively. The results are in excellent agreement with the previously reported data. |
