近年来，随着检测灵敏度和分辨率的提高，该技术在放射性核素含量和同位素比值测定中的应用日益突出。
In recent years, with the improvement of sensitivity and resolution, its application was increasing to determine radionuclides content and isotope ratios.
不过，变质岩中微量碳酸盐的碳含量和碳同位素比值分析能够对原岩类型提供有效的判别。
Nevertheless, the combined carbon content and isotope analyses of micro-carbonate in metamorphic rocks can be used to make a distinction in origin between sedimentary and igneous protoliths.
