岩Sr同位素研究,可以揭示样品自身存在的不均一性,更好地反映样品经历的地质过程,已被广泛应用于各种地质研究领域,如研究壳幔相互作用,岩浆起源和演化,岩浆体系开放性研究,沉积盆地物源示踪及气候环境研究.准确测定Rb-Sr同位素比值是应用该同位素体系的前提.微钻取样-热电离质谱/多接收电感耦合等离子体质谱(TIMS/MC-...
微钻取样-TIMS/MC-ICPMS的最大优势是可获得高精度的Sr同位素数据(外精度优于100×10-6,2SD);但由于需要进行化学处理,流程繁琐耗时(约10天),实验周期较长,同时需要严格控制化学流程空白,且取样直径(200～2000μm)和取样深度(100～2000μm)较大,空间分辨率较低,但是该方法可以对高Rb样品(如钾长石)进行有效...
Two detailed and widely used analysis methods for micro-sample Sr isotope measurement are microdrilling-TIMS /MC-ICPMS and LA-MC-ICPMS. These two methods have different advantages and disadvantages in sample preparation,interference correction and measurement in mass spectrometry. The greatest advantage...
