Research Data -Aeolian Dust Provenance Across the Asian Steppe Revealed by the Oxygen Isotope Composition of Quartz Grains in Topsoil.xlsx

This data includes basic geographical information for 23 locations in the steppe regions of Central Asia and East Asia, namely 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 quartz content and quartz δ¹⁸O data for the surface soil of Japan are from Mizota (1982); Mizota & Matsuhisa (1985); Mizota et al. (1990); Inoue et al. (1993); Eguchi et al. (2012) ; and Nakao et al. (2015).
