Abstract

The REE composition of samples from sand–dust deposit events in Harbin was compared with that of 3 different grain size fractions of sandy soil samples from Horqin Sandy Land and Songnen Sandy Land. The results indicate that the REE distributions of all of the Harbin sand–dust samples are remarkably similar to each other, with distinct negative Eu anomalies and slightly negative Ce anomalies, indicating a stable provenance. Grain size exerts a significant influence on REE compositions, with a negative Eu-anomaly tending to develop with decreasing grain size. However, Ce is less influenced by grain size. The results suggest that the Harbin sand–dust deposits are derived from Horqin Sandy Land and not from Songnen Sandy Land. The importance of the Horqin Sandy Land as a major source of Harbin sand–dust weather is supported by meteorological records and meteorological data
