激光剥蚀电感耦合等离子质谱仪(Laser Ablation-Inductively Coupled Plasma-Mass Spectrometer, LA-ICP-MS)为更详细地探索微量元素在有孔虫方解石壳体中的分布提供了可能,也为有孔虫壳体Mg/Ca值测试提供了一种新的方法。利用LA-ICP-MS技术对擭取自印尼海区的11个钻孔顶部沉积样品中的多枚Globigerinoides ruber壳体进行了共173点位的激光剥蚀Mg/Ca值原位微区和深度分析,发现不同壳体、同一壳体不同房室以及同一房室不同部位之间,从壳壁外部到内部Mg/Ca值的变化是不同的。随后,将利用LA-ICP-MS获得的Mg/Ca值与利用常规测试手段获得的Mg/Ca值进行对比,结果表明利用LA-ICP-MS测试浮游有孔虫壳体Mg/Ca值,不但可以避免常规测试复杂的前处理过程,减少化学药品对实验人员健康的危害,也具有较好的准确度和可靠性。

关键词: Mg/Ca比值, 原位微区深度分析, LA-ICP-MS, Globigerinoides ruber壳体, 印尼海区

Laser Ablation-Inductively Coupled Plasma-Mass Spectrometer (LA-ICP-MS) provides an opportunity for us to perform in-situ microanalysis for depth profiling of elements and trace elements/Calcium ratios in calcite foraminiferal shells. In this study, Globigerinoides ruber shells were investigated with a total of 173 ablating positions from a total of 11 core top sediment samples that retrieved from the Indonesian Seas. The results showed changing compositions of Magnesium and Calcium from the inside to the outside surface for both of intra-test and inter-test. Subsequently, Mg/Ca ratios from the LA-ICP-MS microanalysis were compared with Mg/Ca ratios based on regular analyses, suggesting that LA-ICP-MS microanalysis may provide a comparatively safe and convenient way for investigating Mg/Ca ratio of planktonic foraminiferal shells with considerable reliability and accuracy.

Key words: Mg/Ca ratio, In-situ micro- and depth profiling- analysis, LA-ICP-MS, Globigerinoides ruber shells, Indonesian Seas.
