NanoSIMS analysis of organic matter and minerals in clay-sized fraction of fluvial sediments

We analysied the compostional features of organic matter and mineral particles in the clay-sized fraction of fluvial sediments in Luzon and Taiwan Islands, using NanoSIMS analysis. We find the compositional features are significantly coupled with their spatial distribution localisation within the clay-sized fraction.

本研究采用纳米二次离子质谱（NanoSIMS）分析技术，对吕宋岛与台湾群岛河流沉积物黏粒级组分中的有机质及矿物颗粒的组成特征展开分析。研究发现，有机质与矿物颗粒的组成特征与其在该黏粒级组分内部的空间分布定位存在显著的耦合关系。
