Abstract

RATIONALE

Measurements of the oxygen isotopic composition of materials are widely used in many fields. These oxygen isotopic compositions are expressed using different scales. These scales are only linked indirectly, because water and calcium carbonate reference materials, used to establish these oxygen isotope delta scales, have to be converted to CO first, and the isotopic fractionation of these conversions has only been measured a few times in the past. The anchoring of the two oxygen isotope delta scales is therefore currently suboptimal.

METHODS

Primary reference materials, both waters and calcium carbonates, were pyrolyzed within a single measurement sequence in a high-temperature elemental analyzer-pyrolysis system connected to an isotope ratio mass spectrometer in continuous-flow mode. As calcium carbonate is difficult to pyrolyze completely, additives were added to reach a 100% yield. The δO of the calcium carbonates were normalized on the VSMOW-SLAP scale using VSMOW2 and in-house water references.

RESULTS

The average results of 6 international calcites references measured in five independent sequences of pyrolysis measurements showed a difference of 0.07 to 0.09‰ with the presently described relationship in literature between the δO VPDB and δO VSMOW-SLAP scale.

CONCLUSIONS

The outcome of the study made the direct comparison of the two different O scales possible. Our results demonstrate a small discrepancy in the presently recommended relation between the two oxygen isotope delta scales.

摘要

原理

材料氧同位素组成的测量在许多领域中广泛应用。这些氧同位素组成用不同的标度表示。这些标度只是间接关联，因为用于建立这些氧同位素δ标度的水和碳酸钙参考物质必须先转化为CO，而这些转化过程中的同位素分馏在过去仅被测量过几次。因此，目前两种氧同位素δ标度的锚定并不理想。

方法

水和碳酸钙这两种主要参考物质在与连续流模式的同位素比率质谱仪相连的高温元素分析仪 - 热解系统中，于单个测量序列内进行热解。由于碳酸钙难以完全热解，添加了添加剂以达到100%的产率。碳酸钙的δO使用VSMOW2和内部水参考物质在VSMOW - SLAP标度上进行归一化。

结果

在五个独立的热解测量序列中对6种国际方解石参考物质进行测量的平均结果显示，与目前文献中描述的δO VPDB和δO VSMOW - SLAP标度之间的关系存在0.07至0.09‰的差异。

结论

该研究结果使得直接比较两种不同的氧标度成为可能。我们的结果表明，目前推荐的两种氧同位素δ标度之间的关系存在微小差异。
