Major and trace element analyses of eleven grain-size fractions of river sediments from northern Chilean Patagonia

Abstract: Major elements and zirconium concentrations of eleven grain-size fractions of sediments from six rivers in Chilean Patagonia. All subsamples were measured by ICP-AES after fusion technique. Data was used for investigating the relations between grain size and sediment geochemistry, further developing a method to predict sediment grain size from geochemistry. This work was funded by the National Geographic Society Committee for Research and Exploration (8379-07), FWO research credit (1.5.104.11.N), and UGent BOF HYDROPROX project (01N02216).摘要：智利巴塔哥尼亚地区六条河流沉积物的11个粒度分级样品的常量元素与锆元素浓度数据。所有子样品均经熔融制样技术处理后，通过电感耦合等离子体原子发射光谱法（ICP-AES）完成测定。本研究依托该数据集，探究了沉积物粒度与沉积地球化学特征之间的关联，并进一步构建了一种基于地球化学数据预测沉积物粒度的方法。本研究受到美国国家地理学会研究与探索委员会（编号8379-07）、佛兰芒科学研究基金会（FWO）研究资助（编号1.5.104.11.N）以及根特大学（UGent）专项科研基金（BOF）HYDROPROX项目（编号01N02216）的资助。
