The sources and transport dynamics of eolian sediments in the NE Tibetan Plateau since 6.7 Ma

Our supporting Information includes 18 silicate Sr-Nd isotopes and 2070 grain-size data of red clay and loess samples from 3 core drills on the northeastern Tibetan Plateau.The silicate Sr-Nd isotopes were measured in Nanjing Focu MS Technology Co in 2019. The grain size data were measured in 2015.End-member analysis was performed using AnalySize (Paterson & Heslop, 2015).In addition,Sr-Nd isotopes of red clay and loess sediment on the Chinese loess plateau and εNd(0) of potential source regions were collected from published papers.

本辅助数据集涵盖青藏高原东北部3个钻孔采集的红黏土与黄土样品的18组硅酸盐锶-钕（Sr-Nd）同位素数据，以及2070组粒度测试数据。其中，硅酸盐锶-钕同位素测试工作于2019年由南京富科质谱科技有限公司（Nanjing Focu MS Technology Co）完成；粒度数据的测试则于2015年开展。本研究采用AnalySize软件（Paterson & Heslop, 2015）完成端元分析。此外，本研究还从已发表文献中搜集了中国黄土高原红黏土与黄土沉积物的锶-钕同位素数据，以及潜在物源区的εNd(0)数据。
