Research Data - Aeolian dust provenance across the Eurasian Asian steppe from grain-size dependent quartz δ¹⁸O in surface soils

This data includes orginal basic geographical information for 24 locations in the steppe regions of Central Asia and East Asia, in Ukraine, Kazakhstan, Mongolia, Inner Mongolia of China, and Xinjiang of China. It also includes the particle size distribution (<2 μm, 2—10 μm, 10—20 μm, 20—50 μm), the quartz content and quartz δ¹⁸O data for each particle size range. The reference quartz content and quartz δ¹⁸O data for the surface soil of Japan are from Yan et al. (2014), Huo et al. (2018), and for the surface soil of Japan are from Mizota (1982), Mizota and Matsuhisa (1985), Naruse et al. (1986), Mizota et al. (1990), Mizota et al. (1991), Mizota et al. (1992), Inoue et al. (1993), Eguchi et al. (2012), and Nakao et al. (2015).

本数据集收录了中亚与东亚草原区域24处采样点位的基础地理原始信息，覆盖乌克兰、哈萨克斯坦、蒙古国、中国内蒙古自治区及中国新疆维吾尔自治区。此外还包含各粒径区间（<2 μm、2—10 μm、10—20 μm、20—50 μm）的粒度分布（particle size distribution）数据，以及各粒径区间的石英（quartz）含量与石英氧同位素δ¹⁸O（quartz δ¹⁸O）数据。日本表层土壤的参考石英含量与石英氧同位素δ¹⁸O数据引自Yan等（2014）、Huo等（2018）以及Mizota（1982）、Mizota与Matsuhisa（1985）、Naruse等（1986）、Mizota等（1990）、Mizota等（1991）、Mizota等（1992）、Inoue等（1993）、Eguchi等（2012）与Nakao等（2015）。
