碳酸盐岩锶同位素比值测定中的残渣分析

The Residue Analysis in Determination of Sr Isotopes Ratio of Carbonate

摘要: 通过对经HAc溶解后的碳酸盐样品的残渣进行分析，验证了碳酸盐岩中所合非碳酸盐组分的^87Sr／^86Sr同位素比值较高的事实，同时也论证了HCl溶解碳酸盐岩样品的不足，即造成非碳酸盐的溶解，从而导致^87Sr／^86Sr同位素比值质谱测定结果偏高。

Abstract: Through analysis of residue from carbonate samples dissolved by HAc,it has been proved that 87 Sr/ 86 Sr isotope ratio in non carbonate components from carbonate rocks is higher than that in carbonate itself. This fact shows the shortage of
